Let's divide 813930 by 91
We want to figure out the number of times 813930 can be divided by 91.

On to step 1:
When dividing 8 by 91, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 91

Moving on to step 2:
The number 91 fits into 81 0 times, leaving a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Fetch the next digit (3) from the dividend, attach it to 81 and continue: 813 / 91

On to step 3:
91 can be fit into 813 8 times, resulting in a remainder of 85.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 728 from 813 leaves us with 85.
Bring next digit (9) of the dividend behind the 85 and repeat the process: 859 / 91

On to step 4:
91 goes into 859 9 times with a remainder of 40.
The next digit of our result is 9. 
Result so far: 89.0
Subtract 819 from 859 to get 40.
Bring next digit (3) of the dividend behind the 40 and repeat the process: 403 / 91

Advancing to step 5:
91 can be fit into 403 4 times, resulting in a remainder of 39.
Write down 4 as next digit of the result. 
Result so far: 894.0
Subtracting 364 from 403 leaves us with 39.
Include the next digit (0) from the dividend after 39, then repeat: 390 / 91

Advancing to step 6:
91 can be fit into 390 4 times, resulting in a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 8944.0
Subtract 364 from 390 to get 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 7:
When dividing 260 by 91, we get 2 with a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 8944.2
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 8:
780 divided by 91 is 8 with a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 8944.28
Subtract 728 from 780 to 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.

Let's proceed to step 9:
520 divided by 91 is 5 with a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 8944.285
Subtract 455 from 520 to 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 10:
91 goes into 650 7 times with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 8944.2857
Deduct 637 from 650 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 11:
The number 91 fits into 130 1 times, leaving a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 8944.28571
Deduct 91 from 130 and we're left 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.

Moving on to step 12:
The number 91 fits into 390 4 times, leaving a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 8944.285714
If we take 364 away from 390, we end up 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.

Let's proceed to step 13:
If we divide 260 by 91, we get 2 and a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 8944.2857142
Deduct 182 from 260 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 14:
91 can be fit into 780 8 times, resulting in a remainder of 52.
The next digit of our result is 8. 
Result so far: 8944.28571428
Deduct 728 from 780 and we're left 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.

The final result is 8944.28571428 with a remainder of 5.2e-08.
