865107 divided by 81 
We want to divide 865107 by 81.

Moving on to step 1:
The number 81 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 81

Step 2:
81 goes into 86 1 times with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 81 from 86 and we're left with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 81

On to step 3:
81 goes into 55 0 times with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 55 leaves us with 55.
Grab the next digit (1) from the dividend, add it to 55, then carry on: 551 / 81

Moving on to step 4:
The number 81 fits into 551 6 times, leaving a remainder of 65.
Write down 6 as next digit of the result. 
Result so far: 106.0
The remainder is 65 after subtracting 486 from 551.
Take the next digit (0) from the dividend and append it to 65, then repeat: 650 / 81

Moving on to step 5:
When dividing 650 by 81, we get 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 1068.0
The remainder is 2 after subtracting 648 from 650.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 81

On to step 6:
The number 81 fits into 27 0 times, leaving a remainder of 27.
The next digit of our result is 0. 
Result so far: 10680.0
If we subtract 0 from 27, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 7:
270 divided by 81 is 3 with a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 10680.3
If we subtract 243 from 270, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 8:
81 can be fit into 270 3 times, resulting in a remainder of 27.
The next digit of our result is 3. 
Result so far: 10680.33
Deduct 243 from 270 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

After the division, we end up with 10680.33 and a remainder of 0.027.
