We look at the division of 90513747 by 231 
Our goal is to divide 90513747 by 231.

Going ahead to step 1:
If we divide 9 by 231, 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.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 231

Going ahead to step 2:
231 goes into 90 0 times with a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Include the next digit (5) from the dividend after 90, then repeat: 905 / 231

Advancing to step 3:
231 can be fit into 905 3 times, resulting in a remainder of 212.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 693 from 905 and we're left with 212.
Take the next digit (1) from the dividend and append it to 212, then repeat: 2121 / 231

Step 4:
231 can be fit into 2121 9 times, resulting in a remainder of 42.
Use 9 as the next digit of our solution. 
Result so far: 39.0
If we take 2079 away from 2121, we end up with 42.
Include the next digit (3) from the dividend after 42, then repeat: 423 / 231

Advancing to step 5:
The number 231 fits into 423 1 times, leaving a remainder of 192.
The next digit of our result is 1. 
Result so far: 391.0
The remainder is 192 after subtracting 231 from 423.
Include the next digit (7) from the dividend after 192, then repeat: 1927 / 231

Advancing to step 6:
231 goes into 1927 8 times with a remainder of 79.
The next digit of our result is 8. 
Result so far: 3918.0
Deduct 1848 from 1927 and we're left with 79.
Take the next digit (4) from the dividend and append it to 79, then repeat: 794 / 231

Going ahead to step 7:
231 goes into 794 3 times with a remainder of 101.
Record the quotient 3 as the next digit in the result. 
Result so far: 39183.0
If we take 693 away from 794, we end up with 101.
Fetch the next digit (7) from the dividend, attach it to 101 and continue: 1017 / 231

Step 8:
The number 231 fits into 1017 4 times, leaving a remainder of 93.
The number 4 becomes the next digit in our result. 
Result so far: 391834.0
Deduct 924 from 1017 and we're left with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Advancing to step 9:
231 can be fit into 930 4 times, resulting in a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 391834.4
If we subtract 924 from 930, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 10:
The number 231 fits into 60 0 times, leaving a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 391834.4
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
231 goes into 600 2 times with a remainder of 138.
The number 2 becomes the next digit in our result. 
Result so far: 391834.402
The remainder is 138 after subtracting 462 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Advancing to step 12:
If we divide 1380 by 231, we get 5 and a remainder of 225.
Write down 5 as next digit of the result. 
Result so far: 391834.4025
The remainder is 225 after subtracting 1155 from 1380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Going ahead to step 13:
231 goes into 2250 9 times with a remainder of 171.
Put 9 as the next digit of the answer. 
Result so far: 391834.40259
If we subtract 2079 from 2250, we get 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Step 14:
When dividing 1710 by 231, we get 7 with a remainder of 93.
Use 7 as the next digit of our solution. 
Result so far: 391834.402597
Subtract 1617 from 1710 to get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

On to step 15:
When dividing 930 by 231, we get 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 391834.4025974
Subtract 924 from 930 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 16:
If we divide 60 by 231, we get 0 and a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 391834.4025974
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 391834.4025974, with a leftover of 6e-08.
