We look at the division of 231918 by 91 
We want to divide 231918 by 91.

Going ahead to step 1:
The number 91 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 91

Going ahead to step 2:
The number 91 fits into 23 0 times, leaving a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 23 and we're left with 23.
Append the next digit (1) from the dividend to 23 and continue with: 231 / 91

Advancing to step 3:
The number 91 fits into 231 2 times, leaving a remainder of 49.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 182 from 231 and we're left with 49.
Grab the next digit (9) from the dividend, add it to 49, then carry on: 499 / 91

Advancing to step 4:
91 can be fit into 499 5 times, resulting in a remainder of 44.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
The remainder is 44 after subtracting 455 from 499.
Include the next digit (1) from the dividend after 44, then repeat: 441 / 91

Advancing to step 5:
The number 91 fits into 441 4 times, leaving a remainder of 77.
Use 4 as the next digit of our solution. 
Result so far: 254.0
Subtract 364 from 441 to get 77.
Bring next digit (8) of the dividend behind the 77 and repeat the process: 778 / 91

Going ahead to step 6:
778 divided by 91 is 8 with a remainder of 50.
The next digit of our result is 8. 
Result so far: 2548.0
If we take 728 away from 778, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 7:
91 goes into 500 5 times with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 2548.5
If we take 455 away from 500, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 8:
91 can be fit into 450 4 times, resulting in a remainder of 86.
The next digit of our result is 4. 
Result so far: 2548.54
Subtract 364 from 450 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 9:
860 divided by 91 is 9 with a remainder of 41.
The next digit of our result is 9. 
Result so far: 2548.549
If we subtract 819 from 860, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 10:
The number 91 fits into 410 4 times, leaving a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 2548.5494
If we take 364 away from 410, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 11:
91 can be fit into 460 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 2548.54945
If we take 455 away from 460, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 12:
The number 91 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 2548.54945
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 13:
The number 91 fits into 500 5 times, leaving a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 2548.5494505
The remainder is 45 after subtracting 455 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 14:
The number 91 fits into 450 4 times, leaving a remainder of 86.
Put 4 as the next digit of the answer. 
Result so far: 2548.54945054
Subtract 364 from 450 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

In conclusion, the division gives 2548.54945054 with a balance of 8.6e-08.
