The answer for X divided by Y if X=72 and Y=4 is 18. We can Step 1:
Start by setting it up with the divisor 4 on the left side and the dividend 72 on the right side like this:
4 ⟌ 7 2
Step 2:
The divisor (4) goes into the first digit of the dividend (7), 1 time(s). Therefore, put 1 on top:
1
4 ⟌ 7 2
Step 3:
Multiply the divisor by the result in the previous step (4 x 1 = 4) and write that answer below the dividend.
1
4 ⟌ 7 2
4
Step 4:
Subtract the result in the previous step from the first digit of the dividend (7 - 4 = 3) and write the answer below.
1
4 ⟌ 7 2
- 4
3
Step 5:
Move down the 2nd digit of the dividend (2) like this:
1
4 ⟌ 7 2
- 4
3 2
Step 6:
The divisor (4) goes into the bottom number (32), 8 time(s). Therefore, put 8 on top:
1 8
4 ⟌ 7 2
- 4
3 2
Step 7:
Multiply the divisor by the result in the previous step (4 x 8 = 32) and write that answer at the bottom:
1 8
4 ⟌72
- 4
3 2
3 2
Step 8:
Subtract the result in the previous step from the number written above it. (32 - 32 = 0) and write the answer at the bottom.
1 8
4 ⟌ 7 2
-4
3 2
- 3 2
