How it works
These dividing by multiples of 10 worksheets open on one-digit answers, such as 240 ÷ 30 = 8. Other sheets reach two-digit answers, divisors of 200 to 900, remainders and missing numbers. None is a long division sheet.

Take a zero off both numbers
240 ÷ 30 has the same answer as 24 ÷ 3, because both numbers are ten times as large. 4,800 ÷ 600 loses two zeros and becomes 48 ÷ 6. Answers that are tens: 2,400 ÷ 60 = 40 is the trap: one zero of the dividend is left for the answer.
Where it sits in 5th grade
Common Core 5.NBT.6 asks for quotients with up to four-digit dividends and two-digit divisors, using place value. Division with multiples of 10 is the plainest two-digit divisor there is. The sheets with divisors in the hundreds or five-digit dividends go past that standard.
- On the remainders sheet, stripping the zeros gives 6 R 1 for 250 ÷ 40. The remainder is 10.
- Find the dividend is checked by multiplying: 7 × 40 = 280.
Questions and answers
How do you divide by a multiple of 10?
Take one zero off the divisor and one off the dividend, then divide: 1,560 ÷ 30 becomes 156 ÷ 3 = 52. If the dividend has no zero to give, as in 182 ÷ 20, there is a remainder: 9 R 2.
Is dividing by multiples of 10 a 5th grade skill?
Yes under the Common Core, where two-digit divisors arrive in grade 5. Grade 4 divides by one digit, the size of the warm-up of tens and hundreds by one digit.
Why is 2,000 ÷ 50 equal to 40 and not 4?
A zero comes off both numbers, which leaves 200 ÷ 5, and 200 ÷ 5 = 40. The 50 uses up only one zero of the 2,000.
Do the worksheets come with an answer key?
Yes. The key prints on its own page after the sheet, and Make a new sheet deals new numbers with a new key. Uncheck Answer key before printing to leave it off.
