We're dividing 665337 by 81 
We're looking to find how many times 81 goes into 665337.

Let's proceed to step 1:
When dividing 6 by 81, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 81

Moving on to step 2:
When dividing 66 by 81, we get 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Include the next digit (5) from the dividend after 66, then repeat: 665 / 81

Step 3:
When dividing 665 by 81, we get 8 with a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 648 from 665 leaves us with 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 81

Step 4:
When dividing 173 by 81, we get 2 with a remainder of 11.
The next digit of our result is 2. 
Result so far: 82.0
Deduct 162 from 173 and we're left with 11.
Bring next digit (3) of the dividend behind the 11 and repeat the process: 113 / 81

On to step 5:
If we divide 113 by 81, we get 1 and a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 821.0
Deduct 81 from 113 and we're left with 32.
Append the next digit (7) from the dividend to 32 and continue with: 327 / 81

Moving on to step 6:
The number 81 fits into 327 4 times, leaving a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 8214.0
Subtracting 324 from 327 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
The number 81 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 8214.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
If we divide 300 by 81, we get 3 and a remainder of 57.
Write down 3 as next digit of the result. 
Result so far: 8214.03
If we take 243 away from 300, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 9:
When dividing 570 by 81, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 8214.037
The remainder is 3 after subtracting 567 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 10:
If we divide 30 by 81, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 8214.037
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
If we divide 300 by 81, we get 3 and a remainder of 57.
Write down 3 as next digit of the result. 
Result so far: 8214.03703
The remainder is 57 after subtracting 243 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 12:
570 divided by 81 is 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 8214.037037
If we take 567 away from 570, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 13:
81 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 8214.037037
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 14:
81 can be fit into 300 3 times, resulting in a remainder of 57.
Write down 3 as next digit of the result. 
Result so far: 8214.03703703
The remainder is 57 after subtracting 243 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

The final result is 8214.03703703 with a remainder of 5.7e-08.
