308363 ÷ 15 
Let's see how many times 15 fits into 308363.

Moving on to step 1:
If we divide 3 by 15, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 15

Let's proceed to step 2:
When dividing 30 by 15, we get 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 30 from 30 to get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 15

Going ahead to step 3:
8 divided by 15 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 20.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 15

Going ahead to step 4:
15 goes into 83 5 times with a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 205.0
Subtracting 75 from 83 leaves us with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 15

On to step 5:
The number 15 fits into 86 5 times, leaving a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 2055.0
If we subtract 75 from 86, we get 11.
Bring next digit (3) of the dividend behind the 11 and repeat the process: 113 / 15

Going ahead to step 6:
15 can be fit into 113 7 times, resulting in a remainder of 8.
The next digit of our result is 7. 
Result so far: 20557.0
Deduct 105 from 113 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
80 divided by 15 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 20557.5
Subtracting 75 from 80 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.

Going ahead to step 8:
If we divide 50 by 15, we get 3 and a remainder of 5.
The next digit of our result is 3. 
Result so far: 20557.53
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.

Moving on to step 9:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 20557.533
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.

In conclusion, the division gives 20557.533 with a balance of 0.0005.
