We're dividing 901432 by 72 
We want to divide 901432 by 72.

Advancing to step 1:
The number 72 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 72

On to step 2:
If we divide 90 by 72, we get 1 and a remainder of 18.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 72 from 90 and we're left with 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 72

Moving on to step 3:
72 can be fit into 181 2 times, resulting in a remainder of 37.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 144 from 181 to get 37.
Grab the next digit (4) from the dividend, add it to 37, then carry on: 374 / 72

Going ahead to step 4:
The number 72 fits into 374 5 times, leaving a remainder of 14.
Record the quotient 5 as the next digit in the result. 
Result so far: 125.0
Subtracting 360 from 374 leaves us with 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 72

Step 5:
143 divided by 72 is 1 with a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 1251.0
Subtracting 72 from 143 leaves us with 71.
Bring next digit (2) of the dividend behind the 71 and repeat the process: 712 / 72

Let's proceed to step 6:
72 can be fit into 712 9 times, resulting in a remainder of 64.
Record the quotient 9 as the next digit in the result. 
Result so far: 12519.0
The remainder is 64 after subtracting 648 from 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 7:
72 goes into 640 8 times with a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 12519.8
Subtract 576 from 640 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 8:
The number 72 fits into 640 8 times, leaving a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 12519.88
If we subtract 576 from 640, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 12519.88 with a remainder of 0.064.
