We're dividing 621164 by 72 
Let's see how many times 72 fits into 621164.

On to step 1:
If we divide 6 by 72, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 72

Moving on to step 2:
72 goes into 62 0 times with a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 62 to get 62.
Append the next digit (1) from the dividend to 62 and continue with: 621 / 72

Moving on to step 3:
72 can be fit into 621 8 times, resulting in a remainder of 45.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 576 from 621, we get 45.
Bring next digit (1) of the dividend behind the 45 and repeat the process: 451 / 72

Let's proceed to step 4:
When dividing 451 by 72, we get 6 with a remainder of 19.
Put 6 as the next digit of the answer. 
Result so far: 86.0
The remainder is 19 after subtracting 432 from 451.
Append the next digit (6) from the dividend to 19 and continue with: 196 / 72

On to step 5:
When dividing 196 by 72, we get 2 with a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 862.0
Subtracting 144 from 196 leaves us with 52.
Append the next digit (4) from the dividend to 52 and continue with: 524 / 72

Moving on to step 6:
The number 72 fits into 524 7 times, leaving a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 8627.0
If we take 504 away from 524, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 7:
72 goes into 200 2 times with a remainder of 56.
The next digit of our result is 2. 
Result so far: 8627.2
Deduct 144 from 200 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.

Going ahead to step 8:
560 divided by 72 is 7 with a remainder of 56.
Write down 7 as next digit of the result. 
Result so far: 8627.27
Subtract 504 from 560 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 9:
560 divided by 72 is 7 with a remainder of 56.
Record the quotient 7 as the next digit in the result. 
Result so far: 8627.277
Subtract 504 from 560 to get 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 quotient of the division is 8627.277, and the remainder is 0.0056.
