55710501 divided by 638 
We want to figure out the number of times 55710501 can be divided by 638.

Advancing to step 1:
The number 638 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 638

On to step 2:
If we divide 55 by 638, we get 0 and a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Include the next digit (7) from the dividend after 55, then repeat: 557 / 638

Advancing to step 3:
The number 638 fits into 557 0 times, leaving a remainder of 557.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 557 after subtracting 0 from 557.
Fetch the next digit (1) from the dividend, attach it to 557 and continue: 5571 / 638

Going ahead to step 4:
If we divide 5571 by 638, we get 8 and a remainder of 467.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 5104 from 5571, we get 467.
Take the next digit (0) from the dividend and append it to 467, then repeat: 4670 / 638

On to step 5:
4670 divided by 638 is 7 with a remainder of 204.
Write down 7 as next digit of the result. 
Result so far: 87.0
The remainder is 204 after subtracting 4466 from 4670.
Fetch the next digit (5) from the dividend, attach it to 204 and continue: 2045 / 638

Moving on to step 6:
The number 638 fits into 2045 3 times, leaving a remainder of 131.
The number 3 becomes the next digit in our result. 
Result so far: 873.0
If we subtract 1914 from 2045, we get 131.
Grab the next digit (0) from the dividend, add it to 131, then carry on: 1310 / 638

Moving on to step 7:
The number 638 fits into 1310 2 times, leaving a remainder of 34.
The next digit of our result is 2. 
Result so far: 8732.0
Subtract 1276 from 1310 to get 34.
Take the next digit (1) from the dividend and append it to 34, then repeat: 341 / 638

On to step 8:
638 goes into 341 0 times with a remainder of 341.
Use 0 as the next digit of our solution. 
Result so far: 87320.0
If we subtract 0 from 341, we get 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Going ahead to step 9:
If we divide 3410 by 638, we get 5 and a remainder of 220.
Put 5 as the next digit of the answer. 
Result so far: 87320.5
Deduct 3190 from 3410 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.

Step 10:
If we divide 2200 by 638, we get 3 and a remainder of 286.
Put 3 as the next digit of the answer. 
Result so far: 87320.53
Subtract 1914 from 2200 to get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Moving on to step 11:
The number 638 fits into 2860 4 times, leaving a remainder of 308.
The number 4 becomes the next digit in our result. 
Result so far: 87320.534
Subtracting 2552 from 2860 leaves us 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.

Let's proceed to step 12:
If we divide 3080 by 638, we get 4 and a remainder of 528.
Record the quotient 4 as the next digit in the result. 
Result so far: 87320.5344
Subtracting 2552 from 3080 leaves us with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Our division results in 87320.5344 with a remaining 0.00528.
