420008 ÷ 82 
Our goal is to divide 420008 by 82.

Moving on to step 1:
4 divided by 82 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 82

Going ahead to step 2:
The number 82 fits into 42 0 times, leaving a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Bring next digit (0) of the dividend behind the 42 and repeat the process: 420 / 82

On to step 3:
82 goes into 420 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 410 from 420, we get 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 82

Let's proceed to step 4:
100 divided by 82 is 1 with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
Subtracting 82 from 100 leaves us with 18.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 82

Advancing to step 5:
82 goes into 180 2 times with a remainder of 16.
The next digit of our result is 2. 
Result so far: 512.0
Subtracting 164 from 180 leaves us with 16.
Include the next digit (8) from the dividend after 16, then repeat: 168 / 82

Advancing to step 6:
If we divide 168 by 82, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 5122.0
The remainder is 4 after subtracting 164 from 168.
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 7:
82 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 5122.0
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.

Going ahead to step 8:
If we divide 400 by 82, we get 4 and a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 5122.04
Subtracting 328 from 400 leaves us 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 9:
When dividing 720 by 82, we get 8 with a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 5122.048
If we take 656 away from 720, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 10:
The number 82 fits into 640 7 times, leaving a remainder of 66.
Use 7 as the next digit of our solution. 
Result so far: 5122.0487
If we subtract 574 from 640, we 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.

Moving on to step 11:
82 can be fit into 660 8 times, resulting in a remainder of 4.
The next digit of our result is 8. 
Result so far: 5122.04878
Deduct 656 from 660 and we're left 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 12:
The number 82 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 5122.04878
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
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: 5122.0487804
If we subtract 328 from 400, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 14:
82 goes into 720 8 times with a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 5122.04878048
Deduct 656 from 720 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 5122.04878048, with a leftover of 6.4e-08.
