91083717 ÷ 121 
We're looking to find how many times 121 goes into 91083717.

Advancing to step 1:
121 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 121

Going ahead to step 2:
If we divide 91 by 121, we get 0 and a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Grab the next digit (0) from the dividend, add it to 91, then carry on: 910 / 121

Moving on to step 3:
When dividing 910 by 121, we get 7 with a remainder of 63.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 63 after subtracting 847 from 910.
Include the next digit (8) from the dividend after 63, then repeat: 638 / 121

Advancing to step 4:
When dividing 638 by 121, we get 5 with a remainder of 33.
Use 5 as the next digit of our solution. 
Result so far: 75.0
Subtracting 605 from 638 leaves us with 33.
Take the next digit (3) from the dividend and append it to 33, then repeat: 333 / 121

Step 5:
The number 121 fits into 333 2 times, leaving a remainder of 91.
The number 2 becomes the next digit in our result. 
Result so far: 752.0
The remainder is 91 after subtracting 242 from 333.
Grab the next digit (7) from the dividend, add it to 91, then carry on: 917 / 121

Step 6:
When dividing 917 by 121, we get 7 with a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 7527.0
If we subtract 847 from 917, we get 70.
Bring next digit (1) of the dividend behind the 70 and repeat the process: 701 / 121

Step 7:
701 divided by 121 is 5 with a remainder of 96.
Write down 5 as next digit of the result. 
Result so far: 75275.0
If we take 605 away from 701, we end up with 96.
Fetch the next digit (7) from the dividend, attach it to 96 and continue: 967 / 121

Advancing to step 8:
121 goes into 967 7 times with a remainder of 120.
Write down 7 as next digit of the result. 
Result so far: 752757.0
Subtracting 847 from 967 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 9:
121 can be fit into 1200 9 times, resulting in a remainder of 111.
Write down 9 as next digit of the result. 
Result so far: 752757.9
Subtracting 1089 from 1200 leaves us with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

On to step 10:
The number 121 fits into 1110 9 times, leaving a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 752757.99
If we subtract 1089 from 1110, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

In conclusion, the division gives 752757.99 with a balance of 0.021.
