We look at the division of 799781 by 81 
We want to figure out the number of times 799781 can be divided by 81.

On to step 1:
When dividing 7 by 81, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 81

On to step 2:
If we divide 79 by 81, we get 0 and a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Fetch the next digit (9) from the dividend, attach it to 79 and continue: 799 / 81

Moving on to step 3:
If we divide 799 by 81, we get 9 and a remainder of 70.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 729 away from 799, we end up with 70.
Bring next digit (7) of the dividend behind the 70 and repeat the process: 707 / 81

Going ahead to step 4:
81 can be fit into 707 8 times, resulting in a remainder of 59.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
If we subtract 648 from 707, we get 59.
Append the next digit (8) from the dividend to 59 and continue with: 598 / 81

Step 5:
When dividing 598 by 81, we get 7 with a remainder of 31.
The next digit of our result is 7. 
Result so far: 987.0
Deduct 567 from 598 and we're left with 31.
Fetch the next digit (1) from the dividend, attach it to 31 and continue: 311 / 81

Step 6:
81 goes into 311 3 times with a remainder of 68.
The number 3 becomes the next digit in our result. 
Result so far: 9873.0
Deduct 243 from 311 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 7:
When dividing 680 by 81, we get 8 with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 9873.8
If we subtract 648 from 680, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 8:
81 can be fit into 320 3 times, resulting in a remainder of 77.
Record the quotient 3 as the next digit in the result. 
Result so far: 9873.83
The remainder is 77 after subtracting 243 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 9:
If we divide 770 by 81, we get 9 and a remainder of 41.
The next digit of our result is 9. 
Result so far: 9873.839
If we subtract 729 from 770, we 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.

Moving on to step 10:
81 can be fit into 410 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 9873.8395
Subtract 405 from 410 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.

Moving on to step 11:
If we divide 50 by 81, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 9873.8395
Subtracting 0 from 50 leaves us 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 12:
81 can be fit into 500 6 times, resulting in a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 9873.839506
Deduct 486 from 500 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 13:
When dividing 140 by 81, we get 1 with a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 9873.8395061
Deduct 81 from 140 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 14:
590 divided by 81 is 7 with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 9873.83950617
Subtracting 567 from 590 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The quotient of the division is 9873.83950617, and the remainder is 2.3e-08.
