We look at the division of 621965 by 72 
Let's see how many times 72 fits into 621965.

Advancing to step 1:
The number 72 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 72

Advancing to step 2:
72 can be fit into 62 0 times, resulting in a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 62 and we're left with 62.
Append the next digit (1) from the dividend to 62 and continue with: 621 / 72

Going ahead to step 3:
72 can be fit into 621 8 times, resulting in a remainder of 45.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 576 from 621 and we're left with 45.
Append the next digit (9) from the dividend to 45 and continue with: 459 / 72

Moving on to step 4:
When dividing 459 by 72, we get 6 with a remainder of 27.
Write down 6 as next digit of the result. 
Result so far: 86.0
Deduct 432 from 459 and we're left with 27.
Bring next digit (6) of the dividend behind the 27 and repeat the process: 276 / 72

Let's proceed to step 5:
If we divide 276 by 72, we get 3 and a remainder of 60.
Use 3 as the next digit of our solution. 
Result so far: 863.0
If we take 216 away from 276, we end up with 60.
Include the next digit (5) from the dividend after 60, then repeat: 605 / 72

Going ahead to step 6:
If we divide 605 by 72, we get 8 and a remainder of 29.
The number 8 becomes the next digit in our result. 
Result so far: 8638.0
The remainder is 29 after subtracting 576 from 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 7:
The number 72 fits into 290 4 times, leaving a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 8638.4
Subtract 288 from 290 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
The number 72 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 8638.4
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
When dividing 200 by 72, we get 2 with a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 8638.402
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.

On to step 10:
When dividing 560 by 72, we get 7 with a remainder of 56.
Put 7 as the next digit of the answer. 
Result so far: 8638.4027
If we take 504 away from 560, we end up 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.

Advancing to step 11:
When dividing 560 by 72, we get 7 with a remainder of 56.
The number 7 becomes the next digit in our result. 
Result so far: 8638.40277
If we subtract 504 from 560, we 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 final result is 8638.40277 with a remainder of 5.6e-05.
