We're dividing 90355726 by 638 
We want to divide 90355726 by 638.

Let's proceed to step 1:
If we divide 9 by 638, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 638

On to step 2:
When dividing 90 by 638, we get 0 with a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Include the next digit (3) from the dividend after 90, then repeat: 903 / 638

On to step 3:
If we divide 903 by 638, we get 1 and a remainder of 265.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 638 from 903 and we're left with 265.
Bring next digit (5) of the dividend behind the 265 and repeat the process: 2655 / 638

Let's proceed to step 4:
If we divide 2655 by 638, we get 4 and a remainder of 103.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtracting 2552 from 2655 leaves us with 103.
Take the next digit (5) from the dividend and append it to 103, then repeat: 1035 / 638

Going ahead to step 5:
638 goes into 1035 1 times with a remainder of 397.
Put 1 as the next digit of the answer. 
Result so far: 141.0
If we subtract 638 from 1035, we get 397.
Fetch the next digit (7) from the dividend, attach it to 397 and continue: 3977 / 638

Moving on to step 6:
3977 divided by 638 is 6 with a remainder of 149.
The number 6 becomes the next digit in our result. 
Result so far: 1416.0
If we subtract 3828 from 3977, we get 149.
Fetch the next digit (2) from the dividend, attach it to 149 and continue: 1492 / 638

Going ahead to step 7:
When dividing 1492 by 638, we get 2 with a remainder of 216.
Record the quotient 2 as the next digit in the result. 
Result so far: 14162.0
If we subtract 1276 from 1492, we get 216.
Take the next digit (6) from the dividend and append it to 216, then repeat: 2166 / 638

On to step 8:
638 goes into 2166 3 times with a remainder of 252.
Use 3 as the next digit of our solution. 
Result so far: 141623.0
Subtract 1914 from 2166 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Advancing to step 9:
2520 divided by 638 is 3 with a remainder of 606.
Put 3 as the next digit of the answer. 
Result so far: 141623.3
If we subtract 1914 from 2520, we get 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

Step 10:
The number 638 fits into 6060 9 times, leaving a remainder of 318.
The number 9 becomes the next digit in our result. 
Result so far: 141623.39
If we take 5742 away from 6060, we end up with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Advancing to step 11:
638 can be fit into 3180 4 times, resulting in a remainder of 628.
Write down 4 as next digit of the result. 
Result so far: 141623.394
Subtract 2552 from 3180 to get 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Let's proceed to step 12:
638 can be fit into 6280 9 times, resulting in a remainder of 538.
Use 9 as the next digit of our solution. 
Result so far: 141623.3949
Deduct 5742 from 6280 and we're left with 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Step 13:
638 can be fit into 5380 8 times, resulting in a remainder of 276.
The next digit of our result is 8. 
Result so far: 141623.39498
If we take 5104 away from 5380, we end up with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Step 14:
638 goes into 2760 4 times with a remainder of 208.
Write down 4 as next digit of the result. 
Result so far: 141623.394984
Subtract 2552 from 2760 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Going ahead to step 15:
If we divide 2080 by 638, we get 3 and a remainder of 166.
Use 3 as the next digit of our solution. 
Result so far: 141623.3949843
The remainder is 166 after subtracting 1914 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Advancing to step 16:
When dividing 1660 by 638, we get 2 with a remainder of 384.
Use 2 as the next digit of our solution. 
Result so far: 141623.39498432
Subtracting 1276 from 1660 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

The final outcome is 141623.39498432, with a leftover of 3.84e-07.
