85665 divided by 81 
Our goal is to divide 85665 by 81.

Let's proceed to step 1:
81 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 81

Going ahead to step 2:
85 divided by 81 is 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 81 from 85 and we're left with 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 81

Step 3:
When dividing 46 by 81, we get 0 with a remainder of 46.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 46 after subtracting 0 from 46.
Grab the next digit (6) from the dividend, add it to 46, then carry on: 466 / 81

Step 4:
The number 81 fits into 466 5 times, leaving a remainder of 61.
Write down 5 as next digit of the result. 
Result so far: 105.0
If we subtract 405 from 466, we get 61.
Include the next digit (5) from the dividend after 61, then repeat: 615 / 81

Let's proceed to step 5:
The number 81 fits into 615 7 times, leaving a remainder of 48.
Use 7 as the next digit of our solution. 
Result so far: 1057.0
The remainder is 48 after subtracting 567 from 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 6:
When dividing 480 by 81, we get 5 with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 1057.5
Subtract 405 from 480 to 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.

Step 7:
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: 1057.59
The remainder is 21 after subtracting 729 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 8:
81 goes into 210 2 times with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 1057.592
Subtracting 162 from 210 leaves us 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.

Moving on to step 9:
81 goes into 480 5 times with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 1057.5925
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.

Going ahead to step 10:
When dividing 750 by 81, we get 9 with a remainder of 21.
The next digit of our result is 9. 
Result so far: 1057.59259
Subtracting 729 from 750 leaves us 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.

Advancing to step 11:
If we divide 210 by 81, we get 2 and a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 1057.592592
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:
The number 81 fits into 480 5 times, leaving a remainder of 75.
The next digit of our result is 5. 
Result so far: 1057.5925925
If we take 405 away from 480, we end up 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 13:
750 divided by 81 is 9 with a remainder of 21.
The next digit of our result is 9. 
Result so far: 1057.59259259
If we take 729 away from 750, we end up 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.

The quotient of the division is 1057.59259259, and the remainder is 2.1e-08.
