We look at the division of 810204 by 10 
Let's see how many times 10 fits into 810204.

On to step 1:
10 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 10

Moving on to step 2:
When dividing 81 by 10, we get 8 with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 80 away from 81, we end up with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 10

Let's proceed to step 3:
The number 10 fits into 10 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 81.0
The remainder is 0 after subtracting 10 from 10.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 10

On to step 4:
10 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 810.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 10

Advancing to step 5:
10 goes into 20 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 8102.0
Subtracting 20 from 20 leaves us with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 10

On to step 6:
When dividing 4 by 10, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 81020.0
Deduct 0 from 4 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.

Going ahead to step 7:
When dividing 40 by 10, we get 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 81020.4
The remainder is 0 after subtracting 40 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
10 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 81020.4
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
10 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 81020.4
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 81020.4 with a balance of 0.0.
