233971 divided by 91 
We're looking to find how many times 91 goes into 233971.

Advancing to step 1:
91 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 91

Let's proceed to step 2:
91 can be fit into 23 0 times, resulting in a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 23 and we're left with 23.
Bring next digit (3) of the dividend behind the 23 and repeat the process: 233 / 91

Going ahead to step 3:
233 divided by 91 is 2 with a remainder of 51.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 182 from 233 and we're left with 51.
Grab the next digit (9) from the dividend, add it to 51, then carry on: 519 / 91

Let's proceed to step 4:
91 can be fit into 519 5 times, resulting in a remainder of 64.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Deduct 455 from 519 and we're left with 64.
Include the next digit (7) from the dividend after 64, then repeat: 647 / 91

On to step 5:
If we divide 647 by 91, we get 7 and a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 257.0
Subtract 637 from 647 to get 10.
Fetch the next digit (1) from the dividend, attach it to 10 and continue: 101 / 91

Let's proceed to step 6:
If we divide 101 by 91, we get 1 and a remainder of 10.
The next digit of our result is 1. 
Result so far: 2571.0
The remainder is 10 after subtracting 91 from 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
If we divide 100 by 91, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 2571.1
Subtracting 91 from 100 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 8:
When dividing 90 by 91, we get 0 with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 2571.1
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 9:
The number 91 fits into 900 9 times, leaving a remainder of 81.
The number 9 becomes the next digit in our result. 
Result so far: 2571.109
The remainder is 81 after subtracting 819 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 10:
91 goes into 810 8 times with a remainder of 82.
Record the quotient 8 as the next digit in the result. 
Result so far: 2571.1098
Subtracting 728 from 810 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 11:
91 can be fit into 820 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 2571.10989
If we subtract 819 from 820, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 12:
91 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 2571.10989
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 13:
100 divided by 91 is 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 2571.1098901
Deduct 91 from 100 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 14:
When dividing 90 by 91, we get 0 with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 2571.1098901
The remainder is 90 after subtracting 0 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

The final outcome is 2571.1098901, with a leftover of 9e-08.
