Let's divide 249924 by 15
Our goal is to divide 249924 by 15.

Step 1:
2 divided by 15 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 15

Let's proceed to step 2:
If we divide 24 by 15, we get 1 and a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 15 away from 24, we end up with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 15

Moving on to step 3:
15 goes into 99 6 times with a remainder of 9.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Deduct 90 from 99 and we're left with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 15

Let's proceed to step 4:
If we divide 99 by 15, we get 6 and a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 166.0
If we subtract 90 from 99, we get 9.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 15

Let's proceed to step 5:
92 divided by 15 is 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 1666.0
If we take 90 away from 92, we end up with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 15

Step 6:
15 can be fit into 24 1 times, resulting in a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 16661.0
If we subtract 15 from 24, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
15 can be fit into 90 6 times, resulting in a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 16661.6
If we take 90 away from 90, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
When dividing 0 by 15, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 16661.6
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
When dividing 0 by 15, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 16661.6
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 16661.6, with a leftover of 0.0.
