We look at the division of 648382 by 81 
We want to figure out the number of times 648382 can be divided by 81.

On to step 1:
81 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 81

Let's proceed to step 2:
The number 81 fits into 64 0 times, leaving a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Take the next digit (8) from the dividend and append it to 64, then repeat: 648 / 81

Step 3:
If we divide 648 by 81, we get 8 and a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 648 from 648, we get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 81

Let's proceed to step 4:
3 divided by 81 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 80.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 81

Step 5:
81 can be fit into 38 0 times, resulting in a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 800.0
The remainder is 38 after subtracting 0 from 38.
Include the next digit (2) from the dividend after 38, then repeat: 382 / 81

On to step 6:
382 divided by 81 is 4 with a remainder of 58.
Use 4 as the next digit of our solution. 
Result so far: 8004.0
If we subtract 324 from 382, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 7:
81 can be fit into 580 7 times, resulting in a remainder of 13.
The next digit of our result is 7. 
Result so far: 8004.7
If we take 567 away from 580, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 8:
81 goes into 130 1 times with a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 8004.71
The remainder is 49 after subtracting 81 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 9:
The number 81 fits into 490 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 8004.716
The remainder is 4 after subtracting 486 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
81 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 8004.716
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
If we divide 400 by 81, we get 4 and a remainder of 76.
The next digit of our result is 4. 
Result so far: 8004.71604
Deduct 324 from 400 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 12:
The number 81 fits into 760 9 times, leaving a remainder of 31.
The next digit of our result is 9. 
Result so far: 8004.716049
If we take 729 away from 760, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 13:
If we divide 310 by 81, we get 3 and a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 8004.7160493
Subtracting 243 from 310 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 14:
When dividing 670 by 81, we get 8 with a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 8004.71604938
Subtracting 648 from 670 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 8004.71604938 with a remainder of 2.2e-08.
