Let's divide 8412391 by 91
We're looking to find how many times 91 goes into 8412391.

Let's proceed to step 1:
91 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 91

Moving on to step 2:
When dividing 84 by 91, we get 0 with a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 84, we get 84.
Grab the next digit (1) from the dividend, add it to 84, then carry on: 841 / 91

Let's proceed to step 3:
If we divide 841 by 91, we get 9 and a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 819 from 841 and we're left with 22.
Append the next digit (2) from the dividend to 22 and continue with: 222 / 91

Step 4:
91 can be fit into 222 2 times, resulting in a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 92.0
If we take 182 away from 222, we end up with 40.
Include the next digit (3) from the dividend after 40, then repeat: 403 / 91

On to step 5:
If we divide 403 by 91, we get 4 and a remainder of 39.
The number 4 becomes the next digit in our result. 
Result so far: 924.0
If we subtract 364 from 403, we get 39.
Fetch the next digit (9) from the dividend, attach it to 39 and continue: 399 / 91

Going ahead to step 6:
When dividing 399 by 91, we get 4 with a remainder of 35.
Use 4 as the next digit of our solution. 
Result so far: 9244.0
Subtract 364 from 399 to get 35.
Grab the next digit (1) from the dividend, add it to 35, then carry on: 351 / 91

On to step 7:
The number 91 fits into 351 3 times, leaving a remainder of 78.
Put 3 as the next digit of the answer. 
Result so far: 92443.0
Subtract 273 from 351 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 8:
780 divided by 91 is 8 with a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 92443.8
If we take 728 away from 780, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 9:
When dividing 520 by 91, we get 5 with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 92443.85
If we subtract 455 from 520, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 10:
If we divide 650 by 91, we get 7 and a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 92443.857
The remainder is 13 after subtracting 637 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 11:
91 goes into 130 1 times with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 92443.8571
The remainder is 39 after subtracting 91 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 12:
If we divide 390 by 91, we get 4 and a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 92443.85714
The remainder is 26 after subtracting 364 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 13:
260 divided by 91 is 2 with a remainder of 78.
The number 2 becomes the next digit in our result. 
Result so far: 92443.857142
The remainder is 78 after subtracting 182 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 14:
The number 91 fits into 780 8 times, leaving a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 92443.8571428
The remainder is 52 after subtracting 728 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 15:
91 goes into 520 5 times with a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 92443.85714285
If we subtract 455 from 520, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Our division results in 92443.85714285 with a remaining 6.5e-08.
