Let's divide 793891 by 91
We want to figure out the number of times 793891 can be divided by 91.

On to step 1:
If we divide 7 by 91, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 91

Going ahead to step 2:
When dividing 79 by 91, we get 0 with a remainder of 79.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Append the next digit (3) from the dividend to 79 and continue with: 793 / 91

Going ahead to step 3:
793 divided by 91 is 8 with a remainder of 65.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 728 away from 793, we end up with 65.
Bring next digit (8) of the dividend behind the 65 and repeat the process: 658 / 91

On to step 4:
If we divide 658 by 91, we get 7 and a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
If we take 637 away from 658, we end up with 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 91

Let's proceed to step 5:
When dividing 219 by 91, we get 2 with a remainder of 37.
Put 2 as the next digit of the answer. 
Result so far: 872.0
Subtract 182 from 219 to get 37.
Take the next digit (1) from the dividend and append it to 37, then repeat: 371 / 91

Going ahead to step 6:
If we divide 371 by 91, we get 4 and a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 8724.0
Subtracting 364 from 371 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
70 divided by 91 is 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 8724.0
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 8:
700 divided by 91 is 7 with a remainder of 63.
Record the quotient 7 as the next digit in the result. 
Result so far: 8724.07
The remainder is 63 after subtracting 637 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 9:
91 goes into 630 6 times with a remainder of 84.
The next digit of our result is 6. 
Result so far: 8724.076
The remainder is 84 after subtracting 546 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 10:
When dividing 840 by 91, we get 9 with a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 8724.0769
The remainder is 21 after subtracting 819 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 11:
91 can be fit into 210 2 times, resulting in a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 8724.07692
Deduct 182 from 210 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 12:
If we divide 280 by 91, we get 3 and a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 8724.076923
If we take 273 away from 280, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 13:
91 can be fit into 70 0 times, resulting in a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 8724.076923
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 14:
When dividing 700 by 91, we get 7 with a remainder of 63.
The number 7 becomes the next digit in our result. 
Result so far: 8724.07692307
If we subtract 637 from 700, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

The final result is 8724.07692307 with a remainder of 6.3e-08.
