We look at the division of 13787275 by 638 
We want to figure out the number of times 13787275 can be divided by 638.

On to step 1:
When dividing 1 by 638, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 638

Let's proceed to step 2:
The number 638 fits into 13 0 times, leaving a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 638

Let's proceed to step 3:
The number 638 fits into 137 0 times, leaving a remainder of 137.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 137 after subtracting 0 from 137.
Append the next digit (8) from the dividend to 137 and continue with: 1378 / 638

Let's proceed to step 4:
If we divide 1378 by 638, we get 2 and a remainder of 102.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 1276 away from 1378, we end up with 102.
Grab the next digit (7) from the dividend, add it to 102, then carry on: 1027 / 638

Going ahead to step 5:
When dividing 1027 by 638, we get 1 with a remainder of 389.
Write down 1 as next digit of the result. 
Result so far: 21.0
The remainder is 389 after subtracting 638 from 1027.
Grab the next digit (2) from the dividend, add it to 389, then carry on: 3892 / 638

Going ahead to step 6:
The number 638 fits into 3892 6 times, leaving a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 216.0
The remainder is 64 after subtracting 3828 from 3892.
Include the next digit (7) from the dividend after 64, then repeat: 647 / 638

Advancing to step 7:
The number 638 fits into 647 1 times, leaving a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 2161.0
Subtracting 638 from 647 leaves us with 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 638

Step 8:
638 goes into 95 0 times with a remainder of 95.
The next digit of our result is 0. 
Result so far: 21610.0
If we subtract 0 from 95, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Let's proceed to step 9:
When dividing 950 by 638, we get 1 with a remainder of 312.
Put 1 as the next digit of the answer. 
Result so far: 21610.1
Subtracting 638 from 950 leaves us with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Moving on to step 10:
The number 638 fits into 3120 4 times, leaving a remainder of 568.
Write down 4 as next digit of the result. 
Result so far: 21610.14
Subtracting 2552 from 3120 leaves us with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Step 11:
638 can be fit into 5680 8 times, resulting in a remainder of 576.
Put 8 as the next digit of the answer. 
Result so far: 21610.148
Subtracting 5104 from 5680 leaves us with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

On to step 12:
When dividing 5760 by 638, we get 9 with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 21610.1489
Subtracting 5742 from 5760 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 13:
638 goes into 180 0 times with a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 21610.1489
Subtracting 0 from 180 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 14:
1800 divided by 638 is 2 with a remainder of 524.
Write down 2 as next digit of the result. 
Result so far: 21610.148902
Subtract 1276 from 1800 to get 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Advancing to step 15:
The number 638 fits into 5240 8 times, leaving a remainder of 136.
The next digit of our result is 8. 
Result so far: 21610.1489028
If we take 5104 away from 5240, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Moving on to step 16:
638 goes into 1360 2 times with a remainder of 84.
The number 2 becomes the next digit in our result. 
Result so far: 21610.14890282
Deduct 1276 from 1360 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

In conclusion, the division gives 21610.14890282 with a balance of 8.4e-08.
