817225 ÷ 18 
Our goal is to divide 817225 by 18.

Advancing to step 1:
When dividing 8 by 18, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 18

Let's proceed to step 2:
When dividing 81 by 18, we get 4 with a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 9 after subtracting 72 from 81.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 18

Going ahead 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.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 18

On to step 4:
18 goes into 72 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 454.0
Subtract 72 from 72 to get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 18

Going ahead to step 5:
The number 18 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 4540.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 18

Going ahead to step 6:
If we divide 25 by 18, we get 1 and a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 45401.0
The remainder is 7 after subtracting 18 from 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
If we divide 70 by 18, we get 3 and a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 45401.3
Subtracting 54 from 70 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
18 goes into 160 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 45401.38
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
160 divided by 18 is 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 45401.388
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 45401.388 with a remaining 0.0016.
