We're dividing 304202 by 15 
Let's see how many times 15 fits into 304202.

Advancing to step 1:
15 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 15

Advancing to step 2:
15 goes into 30 2 times with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 30 from 30, we get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 15

Step 3:
If we divide 4 by 15, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 20.0
Subtract 0 from 4 to get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 15

Going ahead to step 4:
If we divide 42 by 15, we get 2 and a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 202.0
The remainder is 12 after subtracting 30 from 42.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 15

Moving on to step 5:
15 goes into 120 8 times with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 2028.0
Subtract 120 from 120 to get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 15

On to step 6:
If we divide 2 by 15, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 20280.0
If we subtract 0 from 2, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
15 can be fit into 20 1 times, resulting in a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 20280.1
Subtracting 15 from 20 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 8:
15 can be fit into 50 3 times, resulting in a remainder of 5.
The next digit of our result is 3. 
Result so far: 20280.13
If we take 45 away from 50, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
50 divided by 15 is 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 20280.133
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 20280.133, with a leftover of 0.0005.
