279945 divided by 15 
Let's see how many times 15 fits into 279945.

Step 1:
15 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 15

On to step 2:
15 goes into 27 1 times with a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 15 from 27 and we're left with 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 15

Advancing to step 3:
129 divided by 15 is 8 with a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we subtract 120 from 129, we get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 15

Step 4:
The number 15 fits into 99 6 times, leaving a remainder of 9.
Record the quotient 6 as the next digit in the result. 
Result so far: 186.0
If we take 90 away from 99, we end up with 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 15

Step 5:
The number 15 fits into 94 6 times, leaving a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 1866.0
If we subtract 90 from 94, we get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 15

On to step 6:
When dividing 45 by 15, we get 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 18663.0
Subtracting 45 from 45 leaves us 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 7:
15 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 18663.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
The number 15 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 18663.0
The remainder is 0 after subtracting 0 from 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 result is 18663.0 with a remainder of 0.0.
