In or around the 4th grade most American students begin learning about the intricacies of dividing numbers. This study is usually combined with lessons regarding fractions and their usefulness in life. However, division is often a difficult concept for students to grasp. It's the opposite of multiplication and can be hard for people to visualize. The other thing that makes division difficult is that fact that many of these types of math problems result in remainders. The idea that one number cannot be evenly, or exactly, divided into another can sometimes leave a youngster's brain crying out "this division does not compute!"
Interpreting remainders requires a higher level of thinking and is much more than just doing the math and calculating the remaining value. The student must figure out what the question is exacting and decide what the remainder means in terms of that question. In fact, when it comes to division problems, there are 4 possible ways to interpret the remainder depending on the specific situation where the division operation is being used:
- Leaving the Remainder - This is the most basic form of interpreting the remainder. In this case, the remainder "remains behind" because it is not needed. For example, how many times can 6 go completely into 13? Typically you would write 2 R1 as the answer but in this case, the solution would be 2. This represents the number of times the whole number, in this case, 6, can go into the number 13 completely. The remainder is discarded because it's not needed and the solution is only the quotient.
- Finding only the Remainder - In this situation, only the remainder is important to the problem. For example, 13/6 would equal 2 R1 but in certain situations only the value of the remainder, in this case, 1, is important. Therefore, the solution to these kinds of problems is the remainder itself.
- Sharing the Remainder - In this situation, the remainder is further split into pieces by making it a fraction instead of just leaving the remainder behind. For example, 13/6 would equal 2 R1 but in some cases, the correct answer would be 2 1/6. This version of interpreting the remainder may not appear in some classrooms until future grades or until the students have mastered the basic division.
- Adjusting the Quotient - In this situation, the resulting whole number answer must be adjusted to account for the fact that the remainder cannot simply be discarded for the answer to make sense. For example, 13/6 would equal 2 R1 but in some cases, the correct answer would be "rounded upward" to 3. In other words, the quotient is increased by 1.
These variations are what makes interpreting remainders so difficult for many students to grasp.
Nonetheless, understanding division, and therefore remainders, is an important concept to fully grasp. When the division of numbers is fully understood, it makes learning higher mathematics concepts much easier. Furthermore, utilizing fractions will become easier and well as sharing multiples of things with other people.

As a father of two children I realized the need for them to get additional practice with division; especially, in the area of interpreting remainders. I decided to write up several practice sheets for them and then share these example problems online so that others can benefit from my work. With that said, here are 40 examples of problems where the student needs to interpreting the remainder to find the correct answer to the question. If you would like to use them for your student or child, copy and paste them into a word document and print them out.

Ten Example Problems for Sharing the Remainder
- Josh, James, Jordan, and Johnny worked hard cleaning up Mr. McGregor's back yard. If Mr. McGregor gave the children a total of $50 for their hard work, how much money would each child get? Answer: 50/4 = 12 R2 which means that each child would get $12 and then there would be $2 left over. However, the remainder can be further split by simply writing a fraction since surely no one would leave the remaining $2 behind: $12 and $2/4 becomes $12.50 each.
- Mom baked a batch of 12 cookies. The dog ate 2 leaving 10 on the tray. If four kids were to split the remaining cookies equally (leaving the tray clean), how many cookies would each child get? Answer: 10/4 = 2 R2 the remainder can be further divided by converting it to a fraction, 2/4. This reduces to 1/2. Therefore, each child would get 2 ½ cookies.

If the prize is split equally amongst the 45 scientists, how much money do they each get? Answer: 1,125,009/45 = 25,000 R9 which converts to $25,000 and $9/45 = $25,000 and $1/5 each which is $25,000.20.
- Six children were making slime. They had a 64oz bottle of glue and poured it equally into six bowls. How much glue did each child get? Answer: 64/6 = 10 R4. The remaining 4oz can be divided into 6 equal parts by using a fraction which results in 4/6oz. This reduces to 2/3oz. Therefore, each child received 10 and 2/3 ounces of glue to make slime with.
- In the nursery were 9 hungry babies. A tired mom warmed up 75 ounces of formula for them to drink. If each baby received the same amount of formula (and none was wasted) how much formula did each baby get to drink? Answer: 75/9 = 8 R3. The remaining 3oz can be divided into 9 equal parts by using a fraction which results in 3/9. This reduces to 1/3. Therefore, each baby received 8 and 1/3 ounces of formula to drink.
- My three brothers and I sold our Nintendo 64 as well as all the games and accessories to a dealer for $425. If the money was split equally amongst the four of us, how much money did we each get?

- A fuel shortage hit southern Tucson and the gas station only had 500gallons of gas left. There were 60 customers waiting for gas. If the gas station owner rationed the fuel and split it equally amongst the 60 customers, how many gallons of gas would each customer get? Answer: 500/60 = 8 R20. The remaining 20 gallons can be divided into 60 equal parts by using a fraction which results in 20/60. This reduces to 1/3. Therefore, each customer received 8 and 1/3 gallons of gas.
- Charles was preparing to take 19 people on a three-day camping adventure. He packed 95 gallons of water for the trip. If each camper (including Charles) gets an equal amount of water for their needs, how much water does everyone get? Answer: 95/20 = 4 R15. The remaining 15 gallons can be divided into 20 equal parts by using a fraction which results in 15/20. This reduces to 3/4. Therefore, each camper will get 4 and 3/4 gallons of water to use.
Ten Example Problems for Adjusting the Quotient
- Charles has 38 books that he wants to put on shelves. Each shelf in is bookcase can hold 8 books. How many shelves does Charles need to hold his books? Answer: 38/8 = 4 R6 which means that 5 shelves would be needed to hold all of the books.
- 28 students are planning to go on the class field trip to the zoo. If the school has to rent vans that hold 8 students each to transport them to the zoo, how many vans must they rent? Answer: 28/8 = 3 R4 which means that 4 vans will be needed to make sure that each student has a ride to the zoo.
