We divide 303536 by 15
We want to figure out the number of times 303536 can be divided by 15.

Advancing to step 1:
If we divide 3 by 15, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 15

On to step 2:
The number 15 fits into 30 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 30 away from 30, we end up with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 15

Going ahead to step 3:
The number 15 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtract 0 from 3 to get 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 15

Let's proceed to step 4:
When dividing 35 by 15, we get 2 with a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 202.0
Deduct 30 from 35 and we're left with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 15

Going ahead to step 5:
The number 15 fits into 53 3 times, leaving a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 2023.0
If we take 45 away from 53, we end up with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 15

On to step 6:
The number 15 fits into 86 5 times, leaving a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 20235.0
Subtract 75 from 86 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
When dividing 110 by 15, we get 7 with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 20235.7
Subtracting 105 from 110 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:
The number 15 fits into 50 3 times, leaving a remainder of 5.
The next digit of our result is 3. 
Result so far: 20235.73
Subtract 45 from 50 to get 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:
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: 20235.733
If we subtract 45 from 50, we get 5.
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 result is 20235.733 with a remainder of 0.0005.
