63144 ÷ 72 
We want to figure out the number of times 63144 can be divided by 72.

Advancing to step 1:
72 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 72

On to step 2:
If we divide 63 by 72, we get 0 and a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Grab the next digit (1) from the dividend, add it to 63, then carry on: 631 / 72

Advancing to step 3:
If we divide 631 by 72, we get 8 and a remainder of 55.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 576 from 631, we get 55.
Grab the next digit (4) from the dividend, add it to 55, then carry on: 554 / 72

Let's proceed to step 4:
If we divide 554 by 72, we get 7 and a remainder of 50.
Write down 7 as next digit of the result. 
Result so far: 87.0
Subtracting 504 from 554 leaves us with 50.
Grab the next digit (4) from the dividend, add it to 50, then carry on: 504 / 72

Let's proceed to step 5:
When dividing 504 by 72, we get 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 877.0
The remainder is 0 after subtracting 504 from 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 6:
If we divide 0 by 72, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 877.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
0 divided by 72 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 877.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 877.0 with a remaining 0.0.
