230510 ÷ 15 
We want to figure out the number of times 230510 can be divided by 15.

Moving on to step 1:
15 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 15

Advancing to step 2:
If we divide 23 by 15, we get 1 and a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 15 away from 23, we end up with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 15

On to step 3:
The number 15 fits into 80 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 75 from 80 leaves us with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 15

On to step 4:
If we divide 55 by 15, we get 3 and a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 153.0
The remainder is 10 after subtracting 45 from 55.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 15

On to step 5:
101 divided by 15 is 6 with a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 1536.0
If we subtract 90 from 101, we get 11.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 15

Step 6:
When dividing 110 by 15, we get 7 with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 15367.0
If we take 105 away from 110, 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.

On to step 7:
When dividing 50 by 15, we get 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 15367.3
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.

Advancing to step 8:
When dividing 50 by 15, we get 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 15367.33
Deduct 45 from 50 and we're left 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.

In conclusion, the division gives 15367.33 with a balance of 0.005.
