We look at the division of 304557 by 17 
Let's see how many times 17 fits into 304557.

Step 1:
17 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
Subtracting 0 from 3 leaves us with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 17

Advancing to step 2:
The number 17 fits into 30 1 times, leaving a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 17 from 30, we get 13.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 17

Step 3:
134 divided by 17 is 7 with a remainder of 15.
The next digit of our result is 7. 
Result so far: 17.0
If we subtract 119 from 134, we get 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 17

Let's proceed to step 4:
When dividing 155 by 17, we get 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 179.0
Subtracting 153 from 155 leaves us with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 17

On to step 5:
The number 17 fits into 25 1 times, leaving a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1791.0
The remainder is 8 after subtracting 17 from 25.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 17

Step 6:
87 divided by 17 is 5 with a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 17915.0
The remainder is 2 after subtracting 85 from 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
The number 17 fits into 20 1 times, leaving a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 17915.1
Subtracting 17 from 20 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 8:
30 divided by 17 is 1 with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 17915.11
The remainder is 13 after subtracting 17 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 17915.11 with a remaining 0.013.
