We look at the division of 13549512 by 637 
We want to figure out the number of times 13549512 can be divided by 637.

On to step 1:
1 divided by 637 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 637

Moving on to step 2:
If we divide 13 by 637, we get 0 and a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 637

Let's proceed to step 3:
When dividing 135 by 637, we get 0 with a remainder of 135.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 135, we get 135.
Append the next digit (4) from the dividend to 135 and continue with: 1354 / 637

Moving on to step 4:
If we divide 1354 by 637, we get 2 and a remainder of 80.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 1274 from 1354 and we're left with 80.
Include the next digit (9) from the dividend after 80, then repeat: 809 / 637

Advancing to step 5:
809 divided by 637 is 1 with a remainder of 172.
Write down 1 as next digit of the result. 
Result so far: 21.0
The remainder is 172 after subtracting 637 from 809.
Grab the next digit (5) from the dividend, add it to 172, then carry on: 1725 / 637

Moving on to step 6:
The number 637 fits into 1725 2 times, leaving a remainder of 451.
Record the quotient 2 as the next digit in the result. 
Result so far: 212.0
If we subtract 1274 from 1725, we get 451.
Include the next digit (1) from the dividend after 451, then repeat: 4511 / 637

On to step 7:
4511 divided by 637 is 7 with a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 2127.0
Deduct 4459 from 4511 and we're left with 52.
Fetch the next digit (2) from the dividend, attach it to 52 and continue: 522 / 637

Let's proceed to step 8:
The number 637 fits into 522 0 times, leaving a remainder of 522.
The number 0 becomes the next digit in our result. 
Result so far: 21270.0
Subtracting 0 from 522 leaves us with 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Going ahead to step 9:
637 goes into 5220 8 times with a remainder of 124.
The next digit of our result is 8. 
Result so far: 21270.8
Subtract 5096 from 5220 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 10:
637 goes into 1240 1 times with a remainder of 603.
The number 1 becomes the next digit in our result. 
Result so far: 21270.81
If we take 637 away from 1240, we end up with 603.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6030, and continue the process.

Advancing to step 11:
If we divide 6030 by 637, we get 9 and a remainder of 297.
The next digit of our result is 9. 
Result so far: 21270.819
The remainder is 297 after subtracting 5733 from 6030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Moving on to step 12:
637 goes into 2970 4 times with a remainder of 422.
Record the quotient 4 as the next digit in the result. 
Result so far: 21270.8194
Deduct 2548 from 2970 and we're left with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Going ahead to step 13:
4220 divided by 637 is 6 with a remainder of 398.
The number 6 becomes the next digit in our result. 
Result so far: 21270.81946
Deduct 3822 from 4220 and we're left with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

On to step 14:
When dividing 3980 by 637, we get 6 with a remainder of 158.
Record the quotient 6 as the next digit in the result. 
Result so far: 21270.819466
The remainder is 158 after subtracting 3822 from 3980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

The final outcome is 21270.819466, with a leftover of 1.58e-05.
