We're dividing 815208 by 18 
We're looking to find how many times 18 goes into 815208.

Going ahead to step 1:
When dividing 8 by 18, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 18

Advancing to step 2:
When dividing 81 by 18, we get 4 with a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 72 from 81 to get 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 18

Let's proceed to step 3:
The number 18 fits into 95 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 45.0
The remainder is 5 after subtracting 90 from 95.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 18

Step 4:
When dividing 52 by 18, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 452.0
If we take 36 away from 52, we end up with 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 18

Moving on to step 5:
18 goes into 160 8 times with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 4528.0
Deduct 144 from 160 and we're left with 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 18

Step 6:
168 divided by 18 is 9 with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 45289.0
The remainder is 6 after subtracting 162 from 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
The number 18 fits into 60 3 times, leaving a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 45289.3
Deduct 54 from 60 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
If we divide 60 by 18, we get 3 and a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 45289.33
Deduct 54 from 60 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The quotient of the division is 45289.33, and the remainder is 0.006.
