We look at the division of 791151 by 81 
We want to figure out the number of times 791151 can be divided by 81.

Going ahead to step 1:
When dividing 7 by 81, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 81

Going ahead to step 2:
When dividing 79 by 81, we get 0 with a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Bring next digit (1) of the dividend behind the 79 and repeat the process: 791 / 81

Step 3:
If we divide 791 by 81, we get 9 and a remainder of 62.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 729 from 791 and we're left with 62.
Take the next digit (1) from the dividend and append it to 62, then repeat: 621 / 81

Step 4:
81 can be fit into 621 7 times, resulting in a remainder of 54.
The next digit of our result is 7. 
Result so far: 97.0
The remainder is 54 after subtracting 567 from 621.
Include the next digit (5) from the dividend after 54, then repeat: 545 / 81

Advancing to step 5:
81 goes into 545 6 times with a remainder of 59.
Record the quotient 6 as the next digit in the result. 
Result so far: 976.0
The remainder is 59 after subtracting 486 from 545.
Take the next digit (1) from the dividend and append it to 59, then repeat: 591 / 81

On to step 6:
When dividing 591 by 81, we get 7 with a remainder of 24.
The number 7 becomes the next digit in our result. 
Result so far: 9767.0
Deduct 567 from 591 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 7:
240 divided by 81 is 2 with a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 9767.2
If we take 162 away from 240, we end up 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 8:
When dividing 780 by 81, we get 9 with a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 9767.29
Deduct 729 from 780 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 9:
81 can be fit into 510 6 times, resulting in a remainder of 24.
The next digit of our result is 6. 
Result so far: 9767.296
Deduct 486 from 510 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
The number 81 fits into 240 2 times, leaving a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 9767.2962
If we subtract 162 from 240, we get 78.
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 11:
The number 81 fits into 780 9 times, leaving a remainder of 51.
The next digit of our result is 9. 
Result so far: 9767.29629
Subtract 729 from 780 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 12:
81 can be fit into 510 6 times, resulting in a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 9767.296296
If we subtract 486 from 510, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 13:
81 can be fit into 240 2 times, resulting in a remainder of 78.
The next digit of our result is 2. 
Result so far: 9767.2962962
If we subtract 162 from 240, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 14:
81 goes into 780 9 times with a remainder of 51.
The number 9 becomes the next digit in our result. 
Result so far: 9767.29629629
Subtract 729 from 780 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final outcome is 9767.29629629, with a leftover of 5.1e-08.
