Let's divide 855287 by 18
We're looking to find how many times 18 goes into 855287.

Step 1:
18 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 18

On to step 2:
The number 18 fits into 85 4 times, leaving a remainder of 13.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 72 away from 85, we end up with 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 18

On to step 3:
18 can be fit into 135 7 times, resulting in a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
Subtracting 126 from 135 leaves us with 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 18

Step 4:
When dividing 92 by 18, we get 5 with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 475.0
If we subtract 90 from 92, we get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 18

Going ahead to step 5:
When dividing 28 by 18, we get 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 4751.0
Subtract 18 from 28 to get 10.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 18

Moving on to step 6:
The number 18 fits into 107 5 times, leaving a remainder of 17.
The next digit of our result is 5. 
Result so far: 47515.0
Subtract 90 from 107 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
170 divided by 18 is 9 with a remainder of 8.
The next digit of our result is 9. 
Result so far: 47515.9
Subtract 162 from 170 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
The number 18 fits into 80 4 times, leaving a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 47515.94
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
If we divide 80 by 18, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 47515.944
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 47515.944 with a remainder of 0.0008.
