We look at the division of 406389 by 82 
We're looking to find how many times 82 goes into 406389.

Let's proceed to step 1:
The number 82 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 82

Moving on to step 2:
82 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Take the next digit (6) from the dividend and append it to 40, then repeat: 406 / 82

Going ahead to step 3:
The number 82 fits into 406 4 times, leaving a remainder of 78.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 328 from 406, we get 78.
Bring next digit (3) of the dividend behind the 78 and repeat the process: 783 / 82

Going ahead to step 4:
783 divided by 82 is 9 with a remainder of 45.
The next digit of our result is 9. 
Result so far: 49.0
Subtract 738 from 783 to get 45.
Append the next digit (8) from the dividend to 45 and continue with: 458 / 82

Moving on to step 5:
458 divided by 82 is 5 with a remainder of 48.
Record the quotient 5 as the next digit in the result. 
Result so far: 495.0
Deduct 410 from 458 and we're left with 48.
Bring next digit (9) of the dividend behind the 48 and repeat the process: 489 / 82

On to step 6:
The number 82 fits into 489 5 times, leaving a remainder of 79.
The next digit of our result is 5. 
Result so far: 4955.0
If we subtract 410 from 489, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 7:
82 goes into 790 9 times with a remainder of 52.
The number 9 becomes the next digit in our result. 
Result so far: 4955.9
If we take 738 away from 790, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 8:
82 goes into 520 6 times with a remainder of 28.
The next digit of our result is 6. 
Result so far: 4955.96
The remainder is 28 after subtracting 492 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 9:
If we divide 280 by 82, we get 3 and a remainder of 34.
The next digit of our result is 3. 
Result so far: 4955.963
If we subtract 246 from 280, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 10:
When dividing 340 by 82, we get 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 4955.9634
Subtracting 328 from 340 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
82 goes into 120 1 times with a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 4955.96341
Deduct 82 from 120 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 12:
82 goes into 380 4 times with a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 4955.963414
If we subtract 328 from 380, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 13:
If we divide 520 by 82, we get 6 and a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 4955.9634146
Subtracting 492 from 520 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 14:
82 goes into 280 3 times with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 4955.96341463
Deduct 246 from 280 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

After the division, we end up with 4955.96341463 and a remainder of 3.4e-08.
