Teaching tips and what to try next

A good fit for fifth graders who handle one-digit divisors and know their multiplication facts well. Rounding the divisor to the nearest ten, for example 34 to 30, gives a sensible first guess for each digit. Writing a short list of multiples of the divisor beside the problem cuts down on erasing, and Long Division With Two-Digit Divisors offers the next step with four-digit dividends.

10 versions, each with its own answer key

Same skill and layout, a fresh set of problems in every version, so children can keep practicing without repeating a page. Problems are not repeated between versions unless a skill has only a small number of possible problems (for example, the addition facts within 10).

About this worksheet

Dividing by a two-digit number is a big step in fifth grade, and the hardest part is often the first guess. Before a child can divide 317 by 42, they need to estimate how many 42s fit in 317. Starting with three-digit dividends keeps the work short, so children can focus on estimating and checking. This fifth-grade worksheet gives nine of these problems.

Every dividend is a three-digit number from 100 to 999, and every divisor is a two-digit number from 12 to 99 that is not a multiple of 10. Six problems have a one-digit quotient, where the whole answer comes from a single good estimate. The other three have a two-digit quotient and take two steps. Many problems have a remainder, written with an R, such as 7 R23. Each of the ten versions has new problems and its own answer key.

How to use it: show your child how to round the divisor to the nearest ten to make a guess. For 317 divided by 42, think 320 divided by 40, which is 8. Then multiply 8 by 42 to test it. If the product is too big, try one less. If the remainder is bigger than the divisor, try one more. Keep a list of the first few multiples of the divisor in the margin to make each guess faster.

The answer key gives every quotient and remainder. For larger dividends, try our Long Division With Two-Digit Divisors worksheet. For division in stories, try our Long Division Word Problems worksheet.
