We look at the division of 72621139 by 63 
Our goal is to divide 72621139 by 63.

Advancing to step 1:
The number 63 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 63

Going ahead to step 2:
63 goes into 72 1 times with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 63 from 72 and we're left with 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 63

On to step 3:
If we divide 96 by 63, we get 1 and a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 63 away from 96, we end up with 33.
Bring next digit (2) of the dividend behind the 33 and repeat the process: 332 / 63

Advancing to step 4:
332 divided by 63 is 5 with a remainder of 17.
The next digit of our result is 5. 
Result so far: 115.0
The remainder is 17 after subtracting 315 from 332.
Fetch the next digit (1) from the dividend, attach it to 17 and continue: 171 / 63

Let's proceed to step 5:
63 goes into 171 2 times with a remainder of 45.
The number 2 becomes the next digit in our result. 
Result so far: 1152.0
The remainder is 45 after subtracting 126 from 171.
Bring next digit (1) of the dividend behind the 45 and repeat the process: 451 / 63

Let's proceed to step 6:
When dividing 451 by 63, we get 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 11527.0
If we subtract 441 from 451, we get 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 63

On to step 7:
103 divided by 63 is 1 with a remainder of 40.
Write down 1 as next digit of the result. 
Result so far: 115271.0
Subtracting 63 from 103 leaves us with 40.
Grab the next digit (9) from the dividend, add it to 40, then carry on: 409 / 63

Moving on to step 8:
409 divided by 63 is 6 with a remainder of 31.
The next digit of our result is 6. 
Result so far: 1152716.0
Subtract 378 from 409 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 9:
310 divided by 63 is 4 with a remainder of 58.
Put 4 as the next digit of the answer. 
Result so far: 1152716.4
Deduct 252 from 310 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 10:
580 divided by 63 is 9 with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 1152716.49
Subtract 567 from 580 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 11:
63 goes into 130 2 times with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 1152716.492
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
63 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 1152716.492
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 13:
If we divide 400 by 63, we get 6 and a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 1152716.49206
The remainder is 22 after subtracting 378 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 14:
The number 63 fits into 220 3 times, leaving a remainder of 31.
Record the quotient 3 as the next digit in the result. 
Result so far: 1152716.492063
If we subtract 189 from 220, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 15:
When dividing 310 by 63, we get 4 with a remainder of 58.
Write down 4 as next digit of the result. 
Result so far: 1152716.4920634
The remainder is 58 after subtracting 252 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 16:
580 divided by 63 is 9 with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 1152716.49206349
Subtract 567 from 580 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 1152716.49206349 and a remainder of 1.3e-08.
