We're dividing 81756877 by 817 
Let's see how many times 817 fits into 81756877.

Going ahead to step 1:
817 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 817

Let's proceed to step 2:
81 divided by 817 is 0 with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Take the next digit (7) from the dividend and append it to 81, then repeat: 817 / 817

Advancing to step 3:
If we divide 817 by 817, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 817 from 817 leaves us with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 817

Advancing to step 4:
817 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 817

On to step 5:
56 divided by 817 is 0 with a remainder of 56.
Write down 0 as next digit of the result. 
Result so far: 100.0
Subtract 0 from 56 to get 56.
Grab the next digit (8) from the dividend, add it to 56, then carry on: 568 / 817

Going ahead to step 6:
817 goes into 568 0 times with a remainder of 568.
Use 0 as the next digit of our solution. 
Result so far: 1000.0
The remainder is 568 after subtracting 0 from 568.
Take the next digit (7) from the dividend and append it to 568, then repeat: 5687 / 817

Moving on to step 7:
817 goes into 5687 6 times with a remainder of 785.
Write down 6 as next digit of the result. 
Result so far: 10006.0
If we take 4902 away from 5687, we end up with 785.
Fetch the next digit (7) from the dividend, attach it to 785 and continue: 7857 / 817

Moving on to step 8:
817 goes into 7857 9 times with a remainder of 504.
The next digit of our result is 9. 
Result so far: 100069.0
Subtract 7353 from 7857 to get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Step 9:
5040 divided by 817 is 6 with a remainder of 138.
Record the quotient 6 as the next digit in the result. 
Result so far: 100069.6
If we take 4902 away from 5040, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Advancing to step 10:
1380 divided by 817 is 1 with a remainder of 563.
The next digit of our result is 1. 
Result so far: 100069.61
Subtract 817 from 1380 to get 563.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5630, and continue the process.

On to step 11:
5630 divided by 817 is 6 with a remainder of 728.
The number 6 becomes the next digit in our result. 
Result so far: 100069.616
Deduct 4902 from 5630 and we're left with 728.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

Going ahead to step 12:
817 goes into 7280 8 times with a remainder of 744.
The next digit of our result is 8. 
Result so far: 100069.6168
If we subtract 6536 from 7280, we get 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

Moving on to step 13:
7440 divided by 817 is 9 with a remainder of 87.
The number 9 becomes the next digit in our result. 
Result so far: 100069.61689
If we subtract 7353 from 7440, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Step 14:
If we divide 870 by 817, we get 1 and a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 100069.616891
Deduct 817 from 870 and we're left 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.

Let's proceed to step 15:
When dividing 530 by 817, we get 0 with a remainder of 530.
The number 0 becomes the next digit in our result. 
Result so far: 100069.616891
If we subtract 0 from 530, we get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Going ahead to step 16:
If we divide 5300 by 817, we get 6 and a remainder of 398.
The next digit of our result is 6. 
Result so far: 100069.61689106
Deduct 4902 from 5300 and we're left with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

The final outcome is 100069.61689106, with a leftover of 3.98e-07.
