We're dividing 303592 by 18 
Let's see how many times 18 fits into 303592.

Moving on to step 1:
When dividing 3 by 18, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 18

Going ahead to step 2:
30 divided by 18 is 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 18 from 30, we get 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 18

Advancing to step 3:
If we divide 123 by 18, we get 6 and a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtract 108 from 123 to get 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 18

Advancing to step 4:
155 divided by 18 is 8 with a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 168.0
If we take 144 away from 155, we end up with 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 18

Moving on to step 5:
18 goes into 119 6 times with a remainder of 11.
The next digit of our result is 6. 
Result so far: 1686.0
If we subtract 108 from 119, we get 11.
Append the next digit (2) from the dividend to 11 and continue with: 112 / 18

Going ahead to step 6:
When dividing 112 by 18, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 16866.0
If we subtract 108 from 112, 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.

On to step 7:
40 divided by 18 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 16866.2
Subtracting 36 from 40 leaves us 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 8:
When dividing 40 by 18, we get 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 16866.22
Subtracting 36 from 40 leaves us 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.

The final result is 16866.22 with a remainder of 0.004.
