Let's divide 503558 by 18
Our goal is to divide 503558 by 18.

Step 1:
If we divide 5 by 18, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 18

Moving on to step 2:
18 can be fit into 50 2 times, resulting in a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 36 from 50, we get 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 18

Let's proceed to step 3:
18 goes into 143 7 times with a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 27.0
The remainder is 17 after subtracting 126 from 143.
Include the next digit (5) from the dividend after 17, then repeat: 175 / 18

Moving on to step 4:
18 can be fit into 175 9 times, resulting in a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 279.0
Subtract 162 from 175 to get 13.
Take the next digit (5) from the dividend and append it to 13, then repeat: 135 / 18

Advancing to step 5:
18 goes into 135 7 times with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 2797.0
If we subtract 126 from 135, we get 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 18

Step 6:
18 goes into 98 5 times with a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 27975.0
Subtracting 90 from 98 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.

Advancing to step 7:
18 can be fit into 80 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 27975.4
If we take 72 away from 80, we end up 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.

Let's proceed to step 8:
The number 18 fits into 80 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 27975.44
If we subtract 72 from 80, we 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.

After the division, we end up with 27975.44 and a remainder of 0.008.
