If we subtract 0 from 8, we get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 82

Let's proceed to step 2:
The number 82 fits into 81 0 times, leaving a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Include the next digit (7) from the dividend after 81, then repeat: 817 / 82

On to step 3:
If we divide 817 by 82, we get 9 and a remainder of 79.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 738 from 817 and we're left with 79.
Grab the next digit (7) from the dividend, add it to 79, then carry on: 797 / 82

Moving on to step 4:
When dividing 797 by 82, we get 9 with a remainder of 59.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
Deduct 738 from 797 and we're left with 59.
Take the next digit (5) from the dividend and append it to 59, then repeat: 595 / 82

Going ahead to step 5:
If we divide 595 by 82, we get 7 and a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 997.0
If we subtract 574 from 595, we get 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 82

Advancing to step 6:
The number 82 fits into 215 2 times, leaving a remainder of 51.
Record the quotient 2 as the next digit in the result. 
Result so far: 9972.0
Subtract 164 from 215 to get 51.
Bring next digit (6) of the dividend behind the 51 and repeat the process: 516 / 82

Advancing to step 7:
The number 82 fits into 516 6 times, leaving a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 99726.0
Deduct 492 from 516 and we're left with 24.
Grab the next digit (1) from the dividend, add it to 24, then carry on: 241 / 82

Advancing to step 8:
The number 82 fits into 241 2 times, leaving a remainder of 77.
Use 2 as the next digit of our solution. 
Result so far: 997262.0
Deduct 164 from 241 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 9:
770 divided by 82 is 9 with a remainder of 32.
Write down 9 as next digit of the result. 
Result so far: 997262.9
Subtract 738 from 770 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
82 goes into 320 3 times with a remainder of 74.
Put 3 as the next digit of the answer. 
Result so far: 997262.93
Subtract 246 from 320 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 11:
When dividing 740 by 82, we get 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 997262.939
Subtract 738 from 740 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 12:
20 divided by 82 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 997262.939
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
82 can be fit into 200 2 times, resulting in a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 997262.93902
The remainder is 36 after subtracting 164 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 14:
82 can be fit into 360 4 times, resulting in a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 997262.939024
Subtracting 328 from 360 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 15:
When dividing 320 by 82, we get 3 with a remainder of 74.
Put 3 as the next digit of the answer. 
Result so far: 997262.9390243
The remainder is 74 after subtracting 246 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 16:
If we divide 740 by 82, we get 9 and a remainder of 2.
The next digit of our result is 9. 
Result so far: 997262.93902439
Deduct 738 from 740 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 997262.93902439 with a balance of 2e-09.
