Let's divide 393902 by 82
Let's see how many times 82 fits into 393902.

Advancing to step 1:
82 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 82

On to step 2:
82 can be fit into 39 0 times, resulting in a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Bring next digit (3) of the dividend behind the 39 and repeat the process: 393 / 82

Step 3:
393 divided by 82 is 4 with a remainder of 65.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 328 from 393 to get 65.
Bring next digit (9) of the dividend behind the 65 and repeat the process: 659 / 82

Advancing to step 4:
If we divide 659 by 82, we get 8 and a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
Deduct 656 from 659 and we're left with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 82

Going ahead to step 5:
82 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 480.0
Subtract 0 from 30 to get 30.
Include the next digit (2) from the dividend after 30, then repeat: 302 / 82

On to step 6:
If we divide 302 by 82, we get 3 and a remainder of 56.
Write down 3 as next digit of the result. 
Result so far: 4803.0
Deduct 246 from 302 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 7:
82 goes into 560 6 times with a remainder of 68.
Use 6 as the next digit of our solution. 
Result so far: 4803.6
If we take 492 away from 560, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 8:
When dividing 680 by 82, we get 8 with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 4803.68
Deduct 656 from 680 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.

Let's proceed to step 9:
82 goes into 240 2 times with a remainder of 76.
The number 2 becomes the next digit in our result. 
Result so far: 4803.682
Subtract 164 from 240 to get 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 10:
If we divide 760 by 82, we get 9 and a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 4803.6829
If we subtract 738 from 760, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 11:
220 divided by 82 is 2 with a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 4803.68292
Deduct 164 from 220 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 12:
82 can be fit into 560 6 times, resulting in a remainder of 68.
Put 6 as the next digit of the answer. 
Result so far: 4803.682926
Deduct 492 from 560 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 13:
If we divide 680 by 82, we get 8 and a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 4803.6829268
Subtract 656 from 680 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 14:
If we divide 240 by 82, we get 2 and a remainder of 76.
Put 2 as the next digit of the answer. 
Result so far: 4803.68292682
Deduct 164 from 240 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.

The final outcome is 4803.68292682, with a leftover of 7.6e-08.
