We divide 121644 by 91
We want to figure out the number of times 121644 can be divided by 91.

Step 1:
1 divided by 91 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 91

Step 2:
When dividing 12 by 91, we get 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 91

Step 3:
If we divide 121 by 91, we get 1 and a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 91 from 121, we get 30.
Fetch the next digit (6) from the dividend, attach it to 30 and continue: 306 / 91

Let's proceed to step 4:
91 goes into 306 3 times with a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 33 after subtracting 273 from 306.
Grab the next digit (4) from the dividend, add it to 33, then carry on: 334 / 91

Moving on to step 5:
334 divided by 91 is 3 with a remainder of 61.
The number 3 becomes the next digit in our result. 
Result so far: 133.0
If we subtract 273 from 334, we get 61.
Append the next digit (4) from the dividend to 61 and continue with: 614 / 91

Advancing to step 6:
The number 91 fits into 614 6 times, leaving a remainder of 68.
Use 6 as the next digit of our solution. 
Result so far: 1336.0
Subtract 546 from 614 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 7:
680 divided by 91 is 7 with a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 1336.7
The remainder is 43 after subtracting 637 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 8:
91 can be fit into 430 4 times, resulting in a remainder of 66.
Write down 4 as next digit of the result. 
Result so far: 1336.74
If we subtract 364 from 430, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 9:
The number 91 fits into 660 7 times, leaving a remainder of 23.
The next digit of our result is 7. 
Result so far: 1336.747
If we subtract 637 from 660, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 10:
91 can be fit into 230 2 times, resulting in a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 1336.7472
If we subtract 182 from 230, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 11:
91 can be fit into 480 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 1336.74725
The remainder is 25 after subtracting 455 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 12:
91 goes into 250 2 times with a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 1336.747252
Deduct 182 from 250 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 13:
91 can be fit into 680 7 times, resulting in a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 1336.7472527
The remainder is 43 after subtracting 637 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 14:
The number 91 fits into 430 4 times, leaving a remainder of 66.
The next digit of our result is 4. 
Result so far: 1336.74725274
Subtract 364 from 430 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

In conclusion, the division gives 1336.74725274 with a balance of 6.6e-08.
