Let's divide 870683 by 81
Our goal is to divide 870683 by 81.

On to step 1:
If we divide 8 by 81, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 81

On to step 2:
If we divide 87 by 81, we get 1 and a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 81 from 87 and we're left with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 81

Moving on to step 3:
81 can be fit into 60 0 times, resulting in a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 60, we end up with 60.
Include the next digit (6) from the dividend after 60, then repeat: 606 / 81

Going ahead to step 4:
81 can be fit into 606 7 times, resulting in a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 107.0
If we subtract 567 from 606, we get 39.
Bring next digit (8) of the dividend behind the 39 and repeat the process: 398 / 81

Advancing to step 5:
If we divide 398 by 81, we get 4 and a remainder of 74.
The next digit of our result is 4. 
Result so far: 1074.0
Deduct 324 from 398 and we're left with 74.
Grab the next digit (3) from the dividend, add it to 74, then carry on: 743 / 81

Moving on to step 6:
81 goes into 743 9 times with a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 10749.0
If we take 729 away from 743, we end up 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.

Going ahead to step 7:
If we divide 140 by 81, we get 1 and a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 10749.1
If we subtract 81 from 140, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 8:
81 goes into 590 7 times with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 10749.17
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.

Moving on to step 9:
81 goes into 230 2 times with a remainder of 68.
Write down 2 as next digit of the result. 
Result so far: 10749.172
The remainder is 68 after subtracting 162 from 230.
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 10:
The number 81 fits into 680 8 times, leaving a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 10749.1728
Subtract 648 from 680 to 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.

Going ahead to step 11:
The number 81 fits into 320 3 times, leaving a remainder of 77.
Use 3 as the next digit of our solution. 
Result so far: 10749.17283
Subtract 243 from 320 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 12:
770 divided by 81 is 9 with a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 10749.172839
Subtracting 729 from 770 leaves us 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 13:
410 divided by 81 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 10749.1728395
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.

On to step 14:
When dividing 50 by 81, we get 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 10749.1728395
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 10749.1728395 with a remainder of 5e-08.
