We look at the division of 813391 by 97 
We want to figure out the number of times 813391 can be divided by 97.

Advancing to step 1:
If we divide 8 by 97, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 97

Moving on to step 2:
The number 97 fits into 81 0 times, leaving a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Bring next digit (3) of the dividend behind the 81 and repeat the process: 813 / 97

Moving on to step 3:
When dividing 813 by 97, we get 8 with a remainder of 37.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 776 from 813 leaves us with 37.
Include the next digit (3) from the dividend after 37, then repeat: 373 / 97

Moving on to step 4:
97 goes into 373 3 times with a remainder of 82.
Put 3 as the next digit of the answer. 
Result so far: 83.0
Deduct 291 from 373 and we're left with 82.
Fetch the next digit (9) from the dividend, attach it to 82 and continue: 829 / 97

Let's proceed to step 5:
If we divide 829 by 97, we get 8 and a remainder of 53.
Record the quotient 8 as the next digit in the result. 
Result so far: 838.0
Deduct 776 from 829 and we're left with 53.
Bring next digit (1) of the dividend behind the 53 and repeat the process: 531 / 97

Going ahead to step 6:
531 divided by 97 is 5 with a remainder of 46.
The number 5 becomes the next digit in our result. 
Result so far: 8385.0
If we take 485 away from 531, we end up 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.

Step 7:
97 goes into 460 4 times with a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 8385.4
If we subtract 388 from 460, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 8:
If we divide 720 by 97, we get 7 and a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 8385.47
If we take 679 away from 720, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 9:
If we divide 410 by 97, we get 4 and a remainder of 22.
The next digit of our result is 4. 
Result so far: 8385.474
If we take 388 away from 410, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
220 divided by 97 is 2 with a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 8385.4742
Subtracting 194 from 220 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.

On to step 11:
When dividing 260 by 97, we get 2 with a remainder of 66.
Record the quotient 2 as the next digit in the result. 
Result so far: 8385.47422
Subtracting 194 from 260 leaves us 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.

After the division, we end up with 8385.47422 and a remainder of 6.6e-05.
