We look at the division of 561512 by 72 
Our goal is to divide 561512 by 72.

Moving on to step 1:
If we divide 5 by 72, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 72

On to step 2:
If we divide 56 by 72, we get 0 and a remainder of 56.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 56, we end up with 56.
Bring next digit (1) of the dividend behind the 56 and repeat the process: 561 / 72

Advancing to step 3:
If we divide 561 by 72, we get 7 and a remainder of 57.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 504 from 561 to get 57.
Bring next digit (5) of the dividend behind the 57 and repeat the process: 575 / 72

Let's proceed to step 4:
72 can be fit into 575 7 times, resulting in a remainder of 71.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
Subtract 504 from 575 to get 71.
Include the next digit (1) from the dividend after 71, then repeat: 711 / 72

On to step 5:
711 divided by 72 is 9 with a remainder of 63.
The next digit of our result is 9. 
Result so far: 779.0
If we subtract 648 from 711, we get 63.
Grab the next digit (2) from the dividend, add it to 63, then carry on: 632 / 72

Let's proceed to step 6:
When dividing 632 by 72, we get 8 with a remainder of 56.
The next digit of our result is 8. 
Result so far: 7798.0
The remainder is 56 after subtracting 576 from 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 7:
72 goes into 560 7 times with a remainder of 56.
Record the quotient 7 as the next digit in the result. 
Result so far: 7798.7
Deduct 504 from 560 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 8:
72 can be fit into 560 7 times, resulting in a remainder of 56.
Record the quotient 7 as the next digit in the result. 
Result so far: 7798.77
Deduct 504 from 560 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final result is 7798.77 with a remainder of 0.056.
