999791 divided by 91 
We want to figure out the number of times 999791 can be divided by 91.

Advancing to step 1:
9 divided by 91 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 91

Step 2:
If we divide 99 by 91, we get 1 and a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 91 from 99 and we're left with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 91

Let's proceed to step 3:
When dividing 89 by 91, we get 0 with a remainder of 89.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 89 after subtracting 0 from 89.
Grab the next digit (7) from the dividend, add it to 89, then carry on: 897 / 91

Advancing to step 4:
91 goes into 897 9 times with a remainder of 78.
Use 9 as the next digit of our solution. 
Result so far: 109.0
The remainder is 78 after subtracting 819 from 897.
Take the next digit (9) from the dividend and append it to 78, then repeat: 789 / 91

Step 5:
The number 91 fits into 789 8 times, leaving a remainder of 61.
Put 8 as the next digit of the answer. 
Result so far: 1098.0
Subtracting 728 from 789 leaves us with 61.
Bring next digit (1) of the dividend behind the 61 and repeat the process: 611 / 91

Advancing to step 6:
91 can be fit into 611 6 times, resulting in a remainder of 65.
Put 6 as the next digit of the answer. 
Result so far: 10986.0
If we subtract 546 from 611, 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.

On to step 7:
When dividing 650 by 91, we get 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 10986.7
If we subtract 637 from 650, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 8:
If we divide 130 by 91, we get 1 and a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 10986.71
Subtracting 91 from 130 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 9:
91 goes into 390 4 times with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 10986.714
Subtracting 364 from 390 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 10:
91 can be fit into 260 2 times, resulting in a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 10986.7142
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.

Advancing to step 11:
780 divided by 91 is 8 with a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 10986.71428
If we subtract 728 from 780, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 12:
The number 91 fits into 520 5 times, leaving a remainder of 65.
The next digit of our result is 5. 
Result so far: 10986.714285
If we take 455 away from 520, we end up with 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 13:
If we divide 650 by 91, we get 7 and a remainder of 13.
The next digit of our result is 7. 
Result so far: 10986.7142857
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.

Advancing to step 14:
The number 91 fits into 130 1 times, leaving a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 10986.71428571
If we take 91 away from 130, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

After the division, we end up with 10986.71428571 and a remainder of 3.9e-08.
