We look at the division of 815702 by 72 
Our goal is to divide 815702 by 72.

Let's proceed to step 1:
72 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 72

Moving on to step 2:
81 divided by 72 is 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 72 from 81 leaves us with 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 72

Going ahead to step 3:
The number 72 fits into 95 1 times, leaving a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 72 from 95, we get 23.
Bring next digit (7) of the dividend behind the 23 and repeat the process: 237 / 72

On to step 4:
When dividing 237 by 72, we get 3 with a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 113.0
Subtract 216 from 237 to get 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 72

Advancing to step 5:
The number 72 fits into 210 2 times, leaving a remainder of 66.
Put 2 as the next digit of the answer. 
Result so far: 1132.0
Subtracting 144 from 210 leaves us with 66.
Bring next digit (2) of the dividend behind the 66 and repeat the process: 662 / 72

Advancing to step 6:
662 divided by 72 is 9 with a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 11329.0
Deduct 648 from 662 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
When dividing 140 by 72, we get 1 with a remainder of 68.
Write down 1 as next digit of the result. 
Result so far: 11329.1
If we subtract 72 from 140, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 8:
When dividing 680 by 72, we get 9 with a remainder of 32.
Put 9 as the next digit of the answer. 
Result so far: 11329.19
Deduct 648 from 680 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
When dividing 320 by 72, we get 4 with a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 11329.194
If we take 288 away from 320, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
72 can be fit into 320 4 times, resulting in a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 11329.1944
Subtracting 288 from 320 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 11329.1944, with a leftover of 0.00032.
