20935552 divided by 638 
We want to figure out the number of times 20935552 can be divided by 638.

Moving on to step 1:
2 divided by 638 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 638

On to step 2:
When dividing 20 by 638, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 638

Advancing to step 3:
When dividing 209 by 638, we get 0 with a remainder of 209.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 209 and we're left with 209.
Fetch the next digit (3) from the dividend, attach it to 209 and continue: 2093 / 638

Step 4:
When dividing 2093 by 638, we get 3 with a remainder of 179.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 1914 from 2093, we get 179.
Take the next digit (5) from the dividend and append it to 179, then repeat: 1795 / 638

On to step 5:
The number 638 fits into 1795 2 times, leaving a remainder of 519.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
Subtract 1276 from 1795 to get 519.
Bring next digit (5) of the dividend behind the 519 and repeat the process: 5195 / 638

Going ahead to step 6:
When dividing 5195 by 638, we get 8 with a remainder of 91.
The number 8 becomes the next digit in our result. 
Result so far: 328.0
The remainder is 91 after subtracting 5104 from 5195.
Fetch the next digit (5) from the dividend, attach it to 91 and continue: 915 / 638

On to step 7:
When dividing 915 by 638, we get 1 with a remainder of 277.
Use 1 as the next digit of our solution. 
Result so far: 3281.0
Subtract 638 from 915 to get 277.
Include the next digit (2) from the dividend after 277, then repeat: 2772 / 638

Moving on to step 8:
638 goes into 2772 4 times with a remainder of 220.
Put 4 as the next digit of the answer. 
Result so far: 32814.0
Deduct 2552 from 2772 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 9:
The number 638 fits into 2200 3 times, leaving a remainder of 286.
Use 3 as the next digit of our solution. 
Result so far: 32814.3
If we take 1914 away from 2200, we end up with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Let's proceed to step 10:
2860 divided by 638 is 4 with a remainder of 308.
Record the quotient 4 as the next digit in the result. 
Result so far: 32814.34
If we take 2552 away from 2860, we end up with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Moving on to step 11:
If we divide 3080 by 638, we get 4 and a remainder of 528.
Put 4 as the next digit of the answer. 
Result so far: 32814.344
The remainder is 528 after subtracting 2552 from 3080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

The quotient of the division is 32814.344, and the remainder is 0.0528.
