855382 ÷ 18 
Our goal is to divide 855382 by 18.

Step 1:
8 divided by 18 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 18

On to step 2:
When dividing 85 by 18, we get 4 with a remainder of 13.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 72 from 85, we get 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 18

Advancing to step 3:
When dividing 135 by 18, we get 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 47.0
Deduct 126 from 135 and we're left with 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 18

Advancing to step 4:
If we divide 93 by 18, we get 5 and a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 475.0
Subtracting 90 from 93 leaves us with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 18

Going ahead to step 5:
18 goes into 38 2 times with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 4752.0
If we take 36 away from 38, we end up with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 18

On to step 6:
The number 18 fits into 22 1 times, leaving a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 47521.0
If we take 18 away from 22, 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.

Advancing to step 7:
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: 47521.2
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
40 divided by 18 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 47521.22
If we subtract 36 from 40, we 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.

The final result is 47521.22 with a remainder of 0.004.
