268999 ÷ 15 
Our goal is to divide 268999 by 15.

Going ahead to step 1:
15 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 15

Let's proceed to step 2:
The number 15 fits into 26 1 times, leaving a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 15 from 26 to get 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 15

Going ahead to step 3:
15 can be fit into 118 7 times, resulting in a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
The remainder is 13 after subtracting 105 from 118.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 15

On to step 4:
15 goes into 139 9 times with a remainder of 4.
The next digit of our result is 9. 
Result so far: 179.0
If we take 135 away from 139, we end up with 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 15

Step 5:
The number 15 fits into 49 3 times, leaving a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 1793.0
The remainder is 4 after subtracting 45 from 49.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 15

On to step 6:
The number 15 fits into 49 3 times, leaving a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 17933.0
Subtract 45 from 49 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
15 goes into 40 2 times with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 17933.2
Subtract 30 from 40 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
If we divide 100 by 15, we get 6 and a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 17933.26
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 17933.266
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 17933.266, with a leftover of 0.001.
