We look at the division of 90115613 by 638 
Let's see how many times 638 fits into 90115613.

Going ahead to step 1:
If we divide 9 by 638, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 638

Step 2:
The number 638 fits into 90 0 times, leaving a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Fetch the next digit (1) from the dividend, attach it to 90 and continue: 901 / 638

Moving on to step 3:
If we divide 901 by 638, we get 1 and a remainder of 263.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 638 from 901 leaves us with 263.
Include the next digit (1) from the dividend after 263, then repeat: 2631 / 638

Let's proceed to step 4:
2631 divided by 638 is 4 with a remainder of 79.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtracting 2552 from 2631 leaves us with 79.
Take the next digit (5) from the dividend and append it to 79, then repeat: 795 / 638

Moving on to step 5:
638 can be fit into 795 1 times, resulting in a remainder of 157.
Use 1 as the next digit of our solution. 
Result so far: 141.0
If we subtract 638 from 795, we get 157.
Grab the next digit (6) from the dividend, add it to 157, then carry on: 1576 / 638

Advancing to step 6:
638 goes into 1576 2 times with a remainder of 300.
The next digit of our result is 2. 
Result so far: 1412.0
The remainder is 300 after subtracting 1276 from 1576.
Take the next digit (1) from the dividend and append it to 300, then repeat: 3001 / 638

On to step 7:
638 goes into 3001 4 times with a remainder of 449.
Use 4 as the next digit of our solution. 
Result so far: 14124.0
Subtract 2552 from 3001 to get 449.
Include the next digit (3) from the dividend after 449, then repeat: 4493 / 638

Let's proceed to step 8:
When dividing 4493 by 638, we get 7 with a remainder of 27.
The next digit of our result is 7. 
Result so far: 141247.0
Deduct 4466 from 4493 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 9:
638 goes into 270 0 times with a remainder of 270.
The next digit of our result is 0. 
Result so far: 141247.0
If we subtract 0 from 270, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 10:
When dividing 2700 by 638, we get 4 with a remainder of 148.
Use 4 as the next digit of our solution. 
Result so far: 141247.04
Subtracting 2552 from 2700 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Let's proceed to step 11:
If we divide 1480 by 638, we get 2 and a remainder of 204.
The number 2 becomes the next digit in our result. 
Result so far: 141247.042
The remainder is 204 after subtracting 1276 from 1480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 12:
638 can be fit into 2040 3 times, resulting in a remainder of 126.
Put 3 as the next digit of the answer. 
Result so far: 141247.0423
The remainder is 126 after subtracting 1914 from 2040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Moving on to step 13:
When dividing 1260 by 638, we get 1 with a remainder of 622.
The next digit of our result is 1. 
Result so far: 141247.04231
Subtracting 638 from 1260 leaves us with 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Moving on to step 14:
6220 divided by 638 is 9 with a remainder of 478.
The next digit of our result is 9. 
Result so far: 141247.042319
If we subtract 5742 from 6220, we get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Going ahead to step 15:
If we divide 4780 by 638, we get 7 and a remainder of 314.
Record the quotient 7 as the next digit in the result. 
Result so far: 141247.0423197
If we subtract 4466 from 4780, we get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Moving on to step 16:
638 can be fit into 3140 4 times, resulting in a remainder of 588.
The number 4 becomes the next digit in our result. 
Result so far: 141247.04231974
If we subtract 2552 from 3140, we get 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Our division results in 141247.04231974 with a remaining 5.88e-07.
