We look at the division of 665196 by 81 
We want to figure out the number of times 665196 can be divided by 81.

Advancing to step 1:
81 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 81

Advancing to step 2:
81 goes into 66 0 times with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Take the next digit (5) from the dividend and append it to 66, then repeat: 665 / 81

Going ahead to step 3:
81 goes into 665 8 times with a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 648 away from 665, we end up with 17.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 81

Advancing to step 4:
171 divided by 81 is 2 with a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 82.0
If we subtract 162 from 171, we get 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 81

Moving on to step 5:
If we divide 99 by 81, we get 1 and a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 821.0
Deduct 81 from 99 and we're left with 18.
Append the next digit (6) from the dividend to 18 and continue with: 186 / 81

Moving on to step 6:
The number 81 fits into 186 2 times, leaving a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 8212.0
The remainder is 24 after subtracting 162 from 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 7:
When dividing 240 by 81, we get 2 with a remainder of 78.
The number 2 becomes the next digit in our result. 
Result so far: 8212.2
The remainder is 78 after subtracting 162 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 8:
81 goes into 780 9 times with a remainder of 51.
The next digit of our result is 9. 
Result so far: 8212.29
Subtract 729 from 780 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 9:
The number 81 fits into 510 6 times, leaving a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 8212.296
Deduct 486 from 510 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
240 divided by 81 is 2 with a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 8212.2962
The remainder is 78 after subtracting 162 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 11:
81 can be fit into 780 9 times, resulting in a remainder of 51.
Write down 9 as next digit of the result. 
Result so far: 8212.29629
The remainder is 51 after subtracting 729 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 12:
When dividing 510 by 81, we get 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 8212.296296
The remainder is 24 after subtracting 486 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 13:
81 goes into 240 2 times with a remainder of 78.
The next digit of our result is 2. 
Result so far: 8212.2962962
Deduct 162 from 240 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 14:
When dividing 780 by 81, we get 9 with a remainder of 51.
Write down 9 as next digit of the result. 
Result so far: 8212.29629629
Subtracting 729 from 780 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Our division results in 8212.29629629 with a remaining 5.1e-08.
