We're dividing 391568 by 82 
We want to figure out the number of times 391568 can be divided by 82.

Going ahead to step 1:
The number 82 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 82

Let's proceed to step 2:
82 can be fit into 39 0 times, resulting in a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Grab the next digit (1) from the dividend, add it to 39, then carry on: 391 / 82

Advancing to step 3:
The number 82 fits into 391 4 times, leaving a remainder of 63.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 328 from 391, we get 63.
Fetch the next digit (5) from the dividend, attach it to 63 and continue: 635 / 82

Advancing to step 4:
The number 82 fits into 635 7 times, leaving a remainder of 61.
The next digit of our result is 7. 
Result so far: 47.0
If we subtract 574 from 635, we get 61.
Append the next digit (6) from the dividend to 61 and continue with: 616 / 82

Let's proceed to step 5:
The number 82 fits into 616 7 times, leaving a remainder of 42.
The number 7 becomes the next digit in our result. 
Result so far: 477.0
Deduct 574 from 616 and we're left with 42.
Append the next digit (8) from the dividend to 42 and continue with: 428 / 82

Step 6:
When dividing 428 by 82, we get 5 with a remainder of 18.
Put 5 as the next digit of the answer. 
Result so far: 4775.0
The remainder is 18 after subtracting 410 from 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
When dividing 180 by 82, we get 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 4775.2
Deduct 164 from 180 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
The number 82 fits into 160 1 times, leaving a remainder of 78.
Write down 1 as next digit of the result. 
Result so far: 4775.21
Deduct 82 from 160 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.

Moving on to step 9:
82 can be fit into 780 9 times, resulting in a remainder of 42.
Write down 9 as next digit of the result. 
Result so far: 4775.219
Subtracting 738 from 780 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 10:
82 goes into 420 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 4775.2195
If we subtract 410 from 420, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
If we divide 100 by 82, we get 1 and a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 4775.21951
The remainder is 18 after subtracting 82 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 12:
180 divided by 82 is 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 4775.219512
If we subtract 164 from 180, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
82 can be fit into 160 1 times, resulting in a remainder of 78.
Record the quotient 1 as the next digit in the result. 
Result so far: 4775.2195121
If we subtract 82 from 160, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 14:
780 divided by 82 is 9 with a remainder of 42.
Use 9 as the next digit of our solution. 
Result so far: 4775.21951219
If we subtract 738 from 780, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 4775.21951219, with a leftover of 4.2e-08.
