Let's divide 879783 by 91
We're looking to find how many times 91 goes into 879783.

Step 1:
91 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 91

Going ahead to step 2:
If we divide 87 by 91, we get 0 and a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Fetch the next digit (9) from the dividend, attach it to 87 and continue: 879 / 91

On to step 3:
If we divide 879 by 91, we get 9 and a remainder of 60.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 819 from 879 to get 60.
Bring next digit (7) of the dividend behind the 60 and repeat the process: 607 / 91

Let's proceed to step 4:
If we divide 607 by 91, we get 6 and a remainder of 61.
Put 6 as the next digit of the answer. 
Result so far: 96.0
Subtracting 546 from 607 leaves us with 61.
Fetch the next digit (8) from the dividend, attach it to 61 and continue: 618 / 91

On to step 5:
91 can be fit into 618 6 times, resulting in a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 966.0
If we subtract 546 from 618, we get 72.
Take the next digit (3) from the dividend and append it to 72, then repeat: 723 / 91

Advancing to step 6:
If we divide 723 by 91, we get 7 and a remainder of 86.
Put 7 as the next digit of the answer. 
Result so far: 9667.0
Deduct 637 from 723 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 7:
860 divided by 91 is 9 with a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 9667.9
The remainder is 41 after subtracting 819 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 8:
91 can be fit into 410 4 times, resulting in a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 9667.94
Subtracting 364 from 410 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 9:
If we divide 460 by 91, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 9667.945
Subtract 455 from 460 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 10:
The number 91 fits into 50 0 times, leaving a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 9667.945
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
If we divide 500 by 91, we get 5 and a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 9667.94505
If we subtract 455 from 500, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 12:
91 goes into 450 4 times with a remainder of 86.
Put 4 as the next digit of the answer. 
Result so far: 9667.945054
Subtracting 364 from 450 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 13:
If we divide 860 by 91, we get 9 and a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 9667.9450549
Subtract 819 from 860 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 14:
When dividing 410 by 91, we get 4 with a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 9667.94505494
Deduct 364 from 410 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The quotient of the division is 9667.94505494, and the remainder is 4.6e-08.
