Division Strategy: Multiplying Up
Example: 362 ÷ 15 15x10=150
15x10=150
15x 2=30
15x 2=30
15 x 24 = 360
+2 362
362 ÷ 15 = 24 R2
or
362 ÷ 15
15 x 20 = 300
15x 4=60
15x24=360
+2= 362
362 ÷ 15 = 24 R2
Division Strategy: Partition the Dividend
Solve each problem by partitioning the dividend into multiples of the divisor. Solve the easier problems and then add the two quotients together to get a final answer.
Example:
72÷5
72 = 50+22
50÷5 = 10
22÷5 = 4r2
72÷5 =14 r2
Division Strategy: Partial Quotients
Step 1: Write a list of easy facts for the divisor. Step 2: Subtract from the dividend an easy multiple of the divisor (e.g. 10x,
100x, 200x etc). Record the partial quotient in a column to the
right of the problem. Step 3: Repeat until the dividend has been reduced to zero or the remainder is
less than the divisor. Step 4: Add up the partial quotients to find the answer.
Example: 3683 ÷ 16 =
230 r3
16 ÷ 3683
-3200 200x16
483
-320 20x16
163
-160 10x16
3 230
3683 ÷ 16 = 230 r3
Example: 362 ÷ 15 15x10=150

15 x 24 = 360
+2 362
