Partial –Quotients Division Algorithm To find the number of 8s in 453, first find all the partial quotients. Record them in a column to the right of the problem. Then add the partial quotients to find the final quotient or answer. EXAMPLE (dividend) (divisor) 456 ÷ 8 Ask: How many 8s are in 456 (at least 50). The first partial quotient is 50. 50 X 8 = 400 Subtract 400 from 456. 8 456 400 50 56 56 7 0 57 Ask: How many 8s are in 56? (7) The second partial quotient is 7. 7 X 8 = 56 Subtract 56 from 56. The difference is 0. So there is no remainder. Add the partial quotients. The answer is 57. 456 ÷ 8 = 57 Long Division (Standard) with Models Use base-10 blocks to model the dividend. Then make trades until you have the correct number of equal groups. (dividend) 3 hundreds cannot be divided into 6 equal groups. So rename 3 hundreds as 30 tens. 377 ÷ 6 6 6 377 36 1 Divide 37 tens into 6 equal groups. Each group has 6 tens and 1 ten remains. 1 ten cannot be divided into 6 equal groups. So rename 1 ten as 10 ones. There are now 17 ones. Divide 17 ones into 6 equal groups. 5 ones remain. Divide 17 ones into 377 ÷ 6 (divisor) 62 R5 6 6 377 36 17 62 6 377 36 17 12 5
