817375 ÷ 18 
Our goal is to divide 817375 by 18.

Step 1:
The number 18 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
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 / 18

Let's proceed to step 2:
81 divided by 18 is 4 with a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 72 from 81, we get 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 18

On to step 3:
18 goes into 97 5 times with a remainder of 7.
The next digit of our result is 5. 
Result so far: 45.0
Subtract 90 from 97 to get 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 18

Advancing to step 4:
73 divided by 18 is 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 454.0
If we take 72 away from 73, we end up with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 18

On to step 5:
If we divide 17 by 18, we get 0 and a remainder of 17.
The next digit of our result is 0. 
Result so far: 4540.0
Subtract 0 from 17 to get 17.
Bring next digit (5) of the dividend behind the 17 and repeat the process: 175 / 18

Let's proceed to step 6:
18 goes into 175 9 times with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 45409.0
Subtract 162 from 175 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
The number 18 fits into 130 7 times, leaving a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 45409.7
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
When dividing 40 by 18, we get 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 45409.72
If we take 36 away from 40, we end up 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 9:
18 can be fit into 40 2 times, resulting in a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 45409.722
Deduct 36 from 40 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.

After the division, we end up with 45409.722 and a remainder of 0.0004.
