Let's divide 865965 by 81
We want to figure out the number of times 865965 can be divided by 81.

Moving on to step 1:
8 divided by 81 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 81

Moving on to step 2:
81 goes into 86 1 times with a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 81 from 86 and we're left with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 81

On to step 3:
55 divided by 81 is 0 with a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 55 and we're left with 55.
Include the next digit (9) from the dividend after 55, then repeat: 559 / 81

Step 4:
559 divided by 81 is 6 with a remainder of 73.
The next digit of our result is 6. 
Result so far: 106.0
If we take 486 away from 559, we end up with 73.
Append the next digit (6) from the dividend to 73 and continue with: 736 / 81

Let's proceed to step 5:
When dividing 736 by 81, we get 9 with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 1069.0
Subtracting 729 from 736 leaves us with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 81

On to step 6:
If we divide 75 by 81, we get 0 and a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 10690.0
Deduct 0 from 75 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 7:
81 can be fit into 750 9 times, resulting in a remainder of 21.
The next digit of our result is 9. 
Result so far: 10690.9
If we subtract 729 from 750, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 8:
81 can be fit into 210 2 times, resulting in a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 10690.92
If we take 162 away from 210, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 9:
81 can be fit into 480 5 times, resulting in a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 10690.925
The remainder is 75 after subtracting 405 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 10:
81 can be fit into 750 9 times, resulting in a remainder of 21.
The next digit of our result is 9. 
Result so far: 10690.9259
Deduct 729 from 750 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 11:
When dividing 210 by 81, we get 2 with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 10690.92592
If we subtract 162 from 210, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 12:
81 goes into 480 5 times with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 10690.925925
If we subtract 405 from 480, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 13:
If we divide 750 by 81, we get 9 and a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 10690.9259259
Subtract 729 from 750 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 14:
81 goes into 210 2 times with a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 10690.92592592
If we take 162 away from 210, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final result is 10690.92592592 with a remainder of 4.8e-08.
