817420 divided by 18 
We want to divide 817420 by 18.

Moving on to step 1:
The number 18 fits into 8 0 times, leaving 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.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 18

Step 2:
The number 18 fits into 81 4 times, leaving a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 72 from 81 to get 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 18

Moving on to step 3:
If we divide 97 by 18, we get 5 and a remainder of 7.
The next digit of our result is 5. 
Result so far: 45.0
If we take 90 away from 97, we end up with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 18

Moving on to step 4:
When dividing 74 by 18, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 454.0
The remainder is 2 after subtracting 72 from 74.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 18

Step 5:
The number 18 fits into 22 1 times, leaving a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 4541.0
Subtracting 18 from 22 leaves us with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 18

Let's proceed to step 6:
When dividing 40 by 18, we get 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 45412.0
Subtract 36 from 40 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 7:
18 can be fit into 40 2 times, resulting in a remainder of 4.
The next digit of our result is 2. 
Result so far: 45412.2
Subtracting 36 from 40 leaves us 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.

Step 8:
When dividing 40 by 18, we get 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 45412.22
Subtract 36 from 40 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.

In conclusion, the division gives 45412.22 with a balance of 0.004.
