We look at the division of 517769 by 81 
We want to figure out the number of times 517769 can be divided by 81.

Let's proceed to step 1:
5 divided by 81 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 81

Advancing to step 2:
81 can be fit into 51 0 times, resulting in a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Fetch the next digit (7) from the dividend, attach it to 51 and continue: 517 / 81

Moving on to step 3:
517 divided by 81 is 6 with a remainder of 31.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 486 from 517 and we're left with 31.
Bring next digit (7) of the dividend behind the 31 and repeat the process: 317 / 81

Let's proceed to step 4:
81 can be fit into 317 3 times, resulting in a remainder of 74.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
If we subtract 243 from 317, we get 74.
Append the next digit (6) from the dividend to 74 and continue with: 746 / 81

Going ahead to step 5:
81 can be fit into 746 9 times, resulting in a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 639.0
Deduct 729 from 746 and we're left with 17.
Fetch the next digit (9) from the dividend, attach it to 17 and continue: 179 / 81

Step 6:
81 can be fit into 179 2 times, resulting in a remainder of 17.
The next digit of our result is 2. 
Result so far: 6392.0
Subtract 162 from 179 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
The number 81 fits into 170 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 6392.2
Subtracting 162 from 170 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
If we divide 80 by 81, we get 0 and a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 6392.2
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 9:
800 divided by 81 is 9 with a remainder of 71.
The next digit of our result is 9. 
Result so far: 6392.209
If we subtract 729 from 800, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 10:
81 can be fit into 710 8 times, resulting in a remainder of 62.
The number 8 becomes the next digit in our result. 
Result so far: 6392.2098
The remainder is 62 after subtracting 648 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 11:
When dividing 620 by 81, we get 7 with a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 6392.20987
If we take 567 away from 620, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 12:
If we divide 530 by 81, we get 6 and a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 6392.209876
If we subtract 486 from 530, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 13:
81 can be fit into 440 5 times, resulting in a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 6392.2098765
Subtracting 405 from 440 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 14:
When dividing 350 by 81, we get 4 with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 6392.20987654
If we subtract 324 from 350, we 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.

The final outcome is 6392.20987654, with a leftover of 2.6e-08.
