108921 divided by 91 
We're looking to find how many times 91 goes into 108921.

On to step 1:
1 divided by 91 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 91

On to step 2:
91 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 91

Advancing to step 3:
91 can be fit into 108 1 times, resulting in a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 17 after subtracting 91 from 108.
Bring next digit (9) of the dividend behind the 17 and repeat the process: 179 / 91

On to step 4:
If we divide 179 by 91, we get 1 and a remainder of 88.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 91 from 179 leaves us with 88.
Fetch the next digit (2) from the dividend, attach it to 88 and continue: 882 / 91

Step 5:
91 goes into 882 9 times with a remainder of 63.
The next digit of our result is 9. 
Result so far: 119.0
Subtracting 819 from 882 leaves us with 63.
Bring next digit (1) of the dividend behind the 63 and repeat the process: 631 / 91

On to step 6:
If we divide 631 by 91, we get 6 and a remainder of 85.
The number 6 becomes the next digit in our result. 
Result so far: 1196.0
The remainder is 85 after subtracting 546 from 631.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 7:
91 goes into 850 9 times with a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 1196.9
Deduct 819 from 850 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 8:
310 divided by 91 is 3 with a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 1196.93
Deduct 273 from 310 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 9:
91 can be fit into 370 4 times, resulting in a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 1196.934
Deduct 364 from 370 and we're left with 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 10:
60 divided by 91 is 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 1196.934
If we subtract 0 from 60, we 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.

Advancing to step 11:
The number 91 fits into 600 6 times, leaving a remainder of 54.
Write down 6 as next digit of the result. 
Result so far: 1196.93406
If we take 546 away from 600, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 12:
The number 91 fits into 540 5 times, leaving a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 1196.934065
If we subtract 455 from 540, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 13:
The number 91 fits into 850 9 times, leaving a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 1196.9340659
Subtracting 819 from 850 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 14:
91 goes into 310 3 times with a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 1196.93406593
Deduct 273 from 310 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

After the division, we end up with 1196.93406593 and a remainder of 3.7e-08.
