269809 ÷ 15 
We want to divide 269809 by 15.

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
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 15

Step 2:
15 goes into 26 1 times with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 15 from 26 to get 11.
Grab the next digit (9) from the dividend, add it to 11, then carry on: 119 / 15

On to step 3:
If we divide 119 by 15, we get 7 and a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we subtract 105 from 119, we get 14.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 15

Moving on to step 4:
When dividing 148 by 15, we get 9 with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 179.0
The remainder is 13 after subtracting 135 from 148.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 15

Let's proceed to step 5:
The number 15 fits into 130 8 times, leaving a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 1798.0
The remainder is 10 after subtracting 120 from 130.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 15

On to step 6:
If we divide 109 by 15, we get 7 and a remainder of 4.
The next digit of our result is 7. 
Result so far: 17987.0
Subtracting 105 from 109 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
When dividing 40 by 15, we get 2 with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 17987.2
Deduct 30 from 40 and we're left 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.

Advancing to step 8:
If we divide 100 by 15, we get 6 and a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 17987.26
Subtract 90 from 100 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.

On to step 9:
100 divided by 15 is 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 17987.266
Subtracting 90 from 100 leaves us 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.

The final outcome is 17987.266, with a leftover of 0.001.
