We divide 558350 by 18
We're looking to find how many times 18 goes into 558350.

Going ahead to step 1:
5 divided by 18 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 18

Going ahead to step 2:
18 goes into 55 3 times with a remainder of 1.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 54 from 55 and we're left with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 18

Let's proceed to step 3:
When dividing 18 by 18, we get 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 31.0
The remainder is 0 after subtracting 18 from 18.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 18

Step 4:
When dividing 3 by 18, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 310.0
If we take 0 away from 3, we end up with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 18

Going ahead to step 5:
When dividing 35 by 18, we get 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 3101.0
Deduct 18 from 35 and we're left with 17.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 18

Moving on to step 6:
18 can be fit into 170 9 times, resulting in a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 31019.0
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.

Going ahead to step 7:
If we divide 80 by 18, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 31019.4
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.

Advancing to step 8:
18 can be fit into 80 4 times, resulting in a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 31019.44
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.

The final result is 31019.44 with a remainder of 0.008.
