550350 divided by 18 
We want to figure out the number of times 550350 can be divided by 18.

Advancing to step 1:
5 divided by 18 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 18

Advancing to step 2:
When dividing 55 by 18, we get 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 54 from 55 to get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 18

Moving on to step 3:
18 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 30.0
Subtracting 0 from 10 leaves us with 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 18

Let's proceed to step 4:
The number 18 fits into 103 5 times, leaving a remainder of 13.
Use 5 as the next digit of our solution. 
Result so far: 305.0
Subtract 90 from 103 to get 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 18

Let's proceed to step 5:
The number 18 fits into 135 7 times, leaving a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 3057.0
The remainder is 9 after subtracting 126 from 135.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 18

Step 6:
The number 18 fits into 90 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 30575.0
Deduct 90 from 90 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
If we divide 0 by 18, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 30575.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
18 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 30575.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 30575.0 with a remainder of 0.0.
