# Divide using partial quotients

Divide using partial quotients is closely related to divide using repeated subtraction

In the lesson about divide using repeated subtraction, we divided 28 by 5 and we came up with the following.

____
5   ) 28
-5                  1
________
23
-5                  1
_________
18
-5                  1
__________
13
-5                  1
__________
8
-5                  1
__________
3

Notice that 5 is subtracted five times. Subtracting 5 fives times is the same as subtracting 25. Therefore, instead of subtracting 5 five times, you can just subtract 25 once.

When you do that, you are just subtracting greater multiples of the divisor.

____
5   ) 28                                             Partial quotients
-25                  5 × 5                              5
_________
3

Since 3 is less than 5, 3 is the remainder. Thus the answer is 5 r3

Example #2.

Use partial quotients to divide 496 by 4

Step 1

Subtract greater multiples of the divisor. Notice that if we were using repeated subtraction, we would have to subtract 4 one hundred times! Now you see why it is good to divide using partial quotients.

Step 2

Subtract lesser multiples of the divisor.

Step 3

All the steps are shown below.

_______
4   ) 496                                                 Partial quotients
-400                  100 × 4                             100
________
96
-80                    20 × 4                                20

________
16
-16                     4 × 4                                  4

________
0

After adding the partial quotients, the answer is 100 + 20 + 4 = 124

496 ÷ 4 = 124
