We look at the division of 249617 by 15 
We want to figure out the number of times 249617 can be divided by 15.

Advancing to step 1:
If we divide 2 by 15, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 15

On to step 2:
24 divided by 15 is 1 with 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

Step 3:
15 goes into 99 6 times with a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 16.0
The remainder is 9 after subtracting 90 from 99.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 15

Advancing to step 4:
The number 15 fits into 96 6 times, leaving a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 166.0
Subtracting 90 from 96 leaves us with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 15

On to step 5:
The number 15 fits into 61 4 times, leaving a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 1664.0
If we subtract 60 from 61, we get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 15

Let's proceed to step 6:
When dividing 17 by 15, we get 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 16641.0
If we subtract 15 from 17, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
The number 15 fits into 20 1 times, leaving a remainder of 5.
The next digit of our result is 1. 
Result so far: 16641.1
Subtract 15 from 20 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 8:
When dividing 50 by 15, we get 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 16641.13
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
When dividing 50 by 15, we get 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 16641.133
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.

The final outcome is 16641.133, with a leftover of 0.0005.
