Long Division — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. 432 ÷ 6 = 72
6 × 72 = 432. Divide 43÷6=7 R1; bring down 2 → 12÷6=2. Quotient = 72.
2. To estimate 318 ÷ 4, use the compatible number 320 ÷ 4 = 80
320 is a compatible number close to 318. 320 ÷ 4 = 80, giving an estimate of about 80.
3. 1,245 ÷ 5 = 249
5 × 249 = 1,245. Divide step by step: 12÷5=2 R2; 24÷5=4 R4; 45÷5=9. Quotient = 249.
4. In 476 ÷ 7, the first step is to divide 47 tens by 7, which gives 6 tens.
47 ÷ 7 = 6 R5. The first digit of the quotient is 6 (in the tens place).
5. 2,016 ÷ 8 = 252
8 × 252 = 2,016. Divide: 20÷8=2 R4; 41÷8=5 R1; 16÷8=2. Quotient = 252.
6. To estimate 563 ÷ 9, use 540 ÷ 9 = 60
540 is a compatible number (divisible by 9). 540 ÷ 9 = 60.
7. 738 ÷ 3 = 246
3 × 246 = 738. Divide: 7÷3=2 R1; 13÷3=4 R1; 18÷3=6. Quotient = 246.
8. 1,904 ÷ 4 = 476
4 × 476 = 1,904. Divide: 19÷4=4 R3; 30÷4=7 R2; 24÷4=6. Quotient = 476.
9. When dividing 625 ÷ 5, the quotient is 125
5 × 125 = 625. Divide: 6÷5=1 R1; 12÷5=2 R2; 25÷5=5. Quotient = 125.
Part B: Matching
