We look at the division of 72570552 by 638 
Let's see how many times 638 fits into 72570552.

Step 1:
If we divide 7 by 638, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 638

Advancing to step 2:
72 divided by 638 is 0 with a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Include the next digit (5) from the dividend after 72, then repeat: 725 / 638

Step 3:
If we divide 725 by 638, we get 1 and a remainder of 87.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 638 from 725, we get 87.
Bring next digit (7) of the dividend behind the 87 and repeat the process: 877 / 638

Moving on to step 4:
638 goes into 877 1 times with a remainder of 239.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 638 away from 877, we end up with 239.
Append the next digit (0) from the dividend to 239 and continue with: 2390 / 638

Let's proceed to step 5:
The number 638 fits into 2390 3 times, leaving a remainder of 476.
Put 3 as the next digit of the answer. 
Result so far: 113.0
If we take 1914 away from 2390, we end up with 476.
Take the next digit (5) from the dividend and append it to 476, then repeat: 4765 / 638

Going ahead to step 6:
The number 638 fits into 4765 7 times, leaving a remainder of 299.
The number 7 becomes the next digit in our result. 
Result so far: 1137.0
If we take 4466 away from 4765, we end up with 299.
Grab the next digit (5) from the dividend, add it to 299, then carry on: 2995 / 638

On to step 7:
When dividing 2995 by 638, we get 4 with a remainder of 443.
Use 4 as the next digit of our solution. 
Result so far: 11374.0
If we take 2552 away from 2995, we end up with 443.
Bring next digit (2) of the dividend behind the 443 and repeat the process: 4432 / 638

Advancing to step 8:
When dividing 4432 by 638, we get 6 with a remainder of 604.
The number 6 becomes the next digit in our result. 
Result so far: 113746.0
Deduct 3828 from 4432 and we're left with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Let's proceed to step 9:
If we divide 6040 by 638, we get 9 and a remainder of 298.
Use 9 as the next digit of our solution. 
Result so far: 113746.9
If we take 5742 away from 6040, we end up with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Step 10:
The number 638 fits into 2980 4 times, leaving a remainder of 428.
Put 4 as the next digit of the answer. 
Result so far: 113746.94
Subtracting 2552 from 2980 leaves us with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Let's proceed to step 11:
If we divide 4280 by 638, we get 6 and a remainder of 452.
Write down 6 as next digit of the result. 
Result so far: 113746.946
If we take 3828 away from 4280, we end up with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Advancing to step 12:
If we divide 4520 by 638, we get 7 and a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 113746.9467
Subtract 4466 from 4520 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 13:
The number 638 fits into 540 0 times, leaving a remainder of 540.
Record the quotient 0 as the next digit in the result. 
Result so far: 113746.9467
If we take 0 away from 540, we end up with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

On to step 14:
If we divide 5400 by 638, we get 8 and a remainder of 296.
Put 8 as the next digit of the answer. 
Result so far: 113746.946708
Deduct 5104 from 5400 and we're left with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 15:
2960 divided by 638 is 4 with a remainder of 408.
Write down 4 as next digit of the result. 
Result so far: 113746.9467084
Deduct 2552 from 2960 and we're left with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

On to step 16:
If we divide 4080 by 638, we get 6 and a remainder of 252.
The number 6 becomes the next digit in our result. 
Result so far: 113746.94670846
The remainder is 252 after subtracting 3828 from 4080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

After the division, we end up with 113746.94670846 and a remainder of 2.52e-07.
