We look at the division of 303820 by 18 
We want to divide 303820 by 18.

Going ahead to step 1:
18 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 18

Advancing to step 2:
The number 18 fits into 30 1 times, leaving a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 18 from 30 to get 12.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 18

Step 3:
When dividing 123 by 18, we get 6 with a remainder of 15.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 108 from 123 leaves us with 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 18

Let's proceed to step 4:
The number 18 fits into 158 8 times, leaving a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 168.0
Deduct 144 from 158 and we're left with 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 18

Going ahead to step 5:
If we divide 142 by 18, we get 7 and a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 1687.0
Subtract 126 from 142 to get 16.
Append the next digit (0) from the dividend to 16 and continue with: 160 / 18

Advancing to step 6:
The number 18 fits into 160 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 16878.0
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
When dividing 160 by 18, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 16878.8
Deduct 144 from 160 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
The number 18 fits into 160 8 times, leaving a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 16878.88
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 16878.88 and a remainder of 0.016.
