We're dividing 807759 by 91 
We're looking to find how many times 91 goes into 807759.

Step 1:
8 divided by 91 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 91

Step 2:
91 goes into 80 0 times with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Grab the next digit (7) from the dividend, add it to 80, then carry on: 807 / 91

Moving on to step 3:
807 divided by 91 is 8 with a remainder of 79.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 728 from 807 and we're left with 79.
Append the next digit (7) from the dividend to 79 and continue with: 797 / 91

On to step 4:
The number 91 fits into 797 8 times, leaving a remainder of 69.
Put 8 as the next digit of the answer. 
Result so far: 88.0
Subtracting 728 from 797 leaves us with 69.
Grab the next digit (5) from the dividend, add it to 69, then carry on: 695 / 91

On to step 5:
The number 91 fits into 695 7 times, leaving a remainder of 58.
Put 7 as the next digit of the answer. 
Result so far: 887.0
Subtract 637 from 695 to get 58.
Grab the next digit (9) from the dividend, add it to 58, then carry on: 589 / 91

Moving on to step 6:
91 can be fit into 589 6 times, resulting in a remainder of 43.
The next digit of our result is 6. 
Result so far: 8876.0
If we take 546 away from 589, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 7:
430 divided by 91 is 4 with a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 8876.4
Deduct 364 from 430 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 8:
The number 91 fits into 660 7 times, leaving a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 8876.47
Deduct 637 from 660 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 9:
The number 91 fits into 230 2 times, leaving a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 8876.472
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.

Going ahead to step 10:
91 goes into 480 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 8876.4725
Subtracting 455 from 480 leaves us with 25.
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 11:
If we divide 250 by 91, we get 2 and a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 8876.47252
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.

Step 12:
If we divide 680 by 91, we get 7 and a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 8876.472527
If we subtract 637 from 680, we get 43.
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 13:
If we divide 430 by 91, we get 4 and a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 8876.4725274
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.

On to step 14:
660 divided by 91 is 7 with a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 8876.47252747
Subtract 637 from 660 to 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.

The final result is 8876.47252747 with a remainder of 2.3e-08.
