We look at the division of 405103 by 82 
We're looking to find how many times 82 goes into 405103.

Step 1:
The number 82 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 82

Let's proceed to step 2:
82 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Take the next digit (5) from the dividend and append it to 40, then repeat: 405 / 82

Let's proceed to step 3:
82 can be fit into 405 4 times, resulting in a remainder of 77.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 77 after subtracting 328 from 405.
Grab the next digit (1) from the dividend, add it to 77, then carry on: 771 / 82

Let's proceed to step 4:
771 divided by 82 is 9 with a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 49.0
Subtracting 738 from 771 leaves us with 33.
Append the next digit (0) from the dividend to 33 and continue with: 330 / 82

Going ahead to step 5:
The number 82 fits into 330 4 times, leaving a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 494.0
Deduct 328 from 330 and we're left with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 82

Let's proceed to step 6:
When dividing 23 by 82, we get 0 with a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 4940.0
Subtract 0 from 23 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
If we divide 230 by 82, we get 2 and a remainder of 66.
The number 2 becomes the next digit in our result. 
Result so far: 4940.2
Subtracting 164 from 230 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 8:
660 divided by 82 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 4940.28
If we take 656 away from 660, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
If we divide 40 by 82, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 4940.28
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
If we divide 400 by 82, we get 4 and a remainder of 72.
Put 4 as the next digit of the answer. 
Result so far: 4940.2804
If we take 328 away from 400, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 11:
82 goes into 720 8 times with a remainder of 64.
The next digit of our result is 8. 
Result so far: 4940.28048
If we subtract 656 from 720, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 12:
If we divide 640 by 82, we get 7 and a remainder of 66.
The next digit of our result is 7. 
Result so far: 4940.280487
Subtract 574 from 640 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 13:
The number 82 fits into 660 8 times, leaving a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 4940.2804878
Subtract 656 from 660 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
If we divide 40 by 82, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 4940.2804878
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 4940.2804878, with a leftover of 4e-08.
