We look at the division of 389866 by 82 
Let's see how many times 82 fits into 389866.

Step 1:
When dividing 3 by 82, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 82

Step 2:
If we divide 38 by 82, we get 0 and a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Grab the next digit (9) from the dividend, add it to 38, then carry on: 389 / 82

Step 3:
82 goes into 389 4 times with a remainder of 61.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 328 away from 389, we end up with 61.
Bring next digit (8) of the dividend behind the 61 and repeat the process: 618 / 82

Advancing to step 4:
82 can be fit into 618 7 times, resulting in a remainder of 44.
Put 7 as the next digit of the answer. 
Result so far: 47.0
Subtract 574 from 618 to get 44.
Bring next digit (6) of the dividend behind the 44 and repeat the process: 446 / 82

Going ahead to step 5:
446 divided by 82 is 5 with a remainder of 36.
Write down 5 as next digit of the result. 
Result so far: 475.0
Subtract 410 from 446 to get 36.
Include the next digit (6) from the dividend after 36, then repeat: 366 / 82

Going ahead to step 6:
The number 82 fits into 366 4 times, leaving a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 4754.0
Deduct 328 from 366 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 7:
If we divide 380 by 82, we get 4 and a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 4754.4
Subtracting 328 from 380 leaves us 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.

Let's proceed to step 8:
The number 82 fits into 520 6 times, leaving a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 4754.46
If we subtract 492 from 520, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
280 divided by 82 is 3 with a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 4754.463
Subtract 246 from 280 to 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.

Moving 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: 4754.4634
If we take 328 away from 340, we end up 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.

Advancing to step 11:
82 can be fit into 120 1 times, resulting in a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 4754.46341
If we subtract 82 from 120, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 12:
If we divide 380 by 82, we get 4 and a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 4754.463414
The remainder is 52 after subtracting 328 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On 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: 4754.4634146
Deduct 492 from 520 and we're left 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:
If we divide 280 by 82, we get 3 and a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 4754.46341463
If we take 246 away from 280, we end up 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.

The final outcome is 4754.46341463, with a leftover of 3.4e-08.
