We look at the division of 915513 by 72 
Let's see how many times 72 fits into 915513.

Going ahead to step 1:
72 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 72

On to step 2:
When dividing 91 by 72, we get 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 72 from 91, we get 19.
Fetch the next digit (5) from the dividend, attach it to 19 and continue: 195 / 72

Step 3:
195 divided by 72 is 2 with a remainder of 51.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 51 after subtracting 144 from 195.
Append the next digit (5) from the dividend to 51 and continue with: 515 / 72

Step 4:
When dividing 515 by 72, we get 7 with a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 127.0
If we take 504 away from 515, we end up with 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 72

Let's proceed to step 5:
72 can be fit into 111 1 times, resulting in a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 1271.0
The remainder is 39 after subtracting 72 from 111.
Append the next digit (3) from the dividend to 39 and continue with: 393 / 72

On to step 6:
The number 72 fits into 393 5 times, leaving a remainder of 33.
Put 5 as the next digit of the answer. 
Result so far: 12715.0
If we subtract 360 from 393, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 7:
If we divide 330 by 72, we get 4 and a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 12715.4
If we subtract 288 from 330, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 8:
420 divided by 72 is 5 with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 12715.45
If we take 360 away from 420, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
If we divide 600 by 72, we get 8 and a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 12715.458
If we take 576 away from 600, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
72 goes into 240 3 times with a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 12715.4583
If we subtract 216 from 240, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
240 divided by 72 is 3 with a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 12715.45833
If we take 216 away from 240, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 12715.45833 with a remainder of 2.4e-05.
