We look at the division of 645056 by 72 
We want to divide 645056 by 72.

Moving on to step 1:
The number 72 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 72

Going ahead to step 2:
64 divided by 72 is 0 with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Include the next digit (5) from the dividend after 64, then repeat: 645 / 72

Moving on to step 3:
The number 72 fits into 645 8 times, leaving a remainder of 69.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 576 from 645 and we're left with 69.
Fetch the next digit (0) from the dividend, attach it to 69 and continue: 690 / 72

Going ahead to step 4:
The number 72 fits into 690 9 times, leaving a remainder of 42.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
The remainder is 42 after subtracting 648 from 690.
Include the next digit (5) from the dividend after 42, then repeat: 425 / 72

Advancing to step 5:
72 can be fit into 425 5 times, resulting in a remainder of 65.
The next digit of our result is 5. 
Result so far: 895.0
The remainder is 65 after subtracting 360 from 425.
Bring next digit (6) of the dividend behind the 65 and repeat the process: 656 / 72

On to step 6:
72 can be fit into 656 9 times, resulting in a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 8959.0
Deduct 648 from 656 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
When dividing 80 by 72, we get 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 8959.1
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
The number 72 fits into 80 1 times, leaving a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 8959.11
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 8959.11, and the remainder is 0.008.
