We look at the division of 255409 by 14 
Let's see how many times 14 fits into 255409.

On to step 1:
When dividing 2 by 14, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 14

Moving on to step 2:
25 divided by 14 is 1 with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 14 away from 25, we end up with 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 14

Advancing to step 3:
115 divided by 14 is 8 with a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtracting 112 from 115 leaves us with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 14

Advancing to step 4:
14 goes into 34 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 182.0
Subtracting 28 from 34 leaves us with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 14

Moving on to step 5:
When dividing 60 by 14, we get 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 1824.0
If we subtract 56 from 60, we get 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 14

Moving on to step 6:
If we divide 49 by 14, we get 3 and a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 18243.0
Subtract 42 from 49 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
70 divided by 14 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 18243.5
If we subtract 70 from 70, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
When dividing 0 by 14, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 18243.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
14 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 18243.5
Subtract 0 from 0 to get 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 outcome is 18243.5, with a leftover of 0.0.
