We divide 249749 by 15
We want to figure out the number of times 249749 can be divided by 15.

Moving on to step 1:
15 can be fit into 2 0 times, resulting in 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 (4) of the dividend behind the 2 and repeat the process: 24 / 15

Let's proceed to step 2:
The number 15 fits into 24 1 times, leaving a remainder of 9.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 15 from 24 leaves us with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 15

Moving on to step 3:
The number 15 fits into 99 6 times, leaving a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtracting 90 from 99 leaves us with 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 15

Step 4:
97 divided by 15 is 6 with a remainder of 7.
The next digit of our result is 6. 
Result so far: 166.0
Subtract 90 from 97 to get 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 15

Let's proceed to step 5:
If we divide 74 by 15, we get 4 and a remainder of 14.
The next digit of our result is 4. 
Result so far: 1664.0
If we take 60 away from 74, we end up with 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 15

Advancing to step 6:
When dividing 149 by 15, we get 9 with a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 16649.0
Subtracting 135 from 149 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 7:
When dividing 140 by 15, we get 9 with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 16649.9
If we take 135 away from 140, 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.

Step 8:
50 divided by 15 is 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 16649.93
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.

Advancing to step 9:
50 divided by 15 is 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 16649.933
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 outcome is 16649.933, with a leftover of 0.0005.
