We look at the division of 255488 by 1 
We want to figure out the number of times 255488 can be divided by 1.

On to step 1:
When dividing 2 by 1, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 0 after subtracting 2 from 2.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 1

Going ahead to step 2:
When dividing 5 by 1, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtracting 5 from 5 leaves us with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 1

Step 3:
5 divided by 1 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 255.0
If we take 5 away from 5, we end up with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

Moving on to step 4:
If we divide 4 by 1, we get 4 and a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 2554.0
If we take 4 away from 4, we end up with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 1

Moving on to step 5:
1 goes into 8 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 25548.0
If we subtract 8 from 8, we get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 1

Step 6:
8 divided by 1 is 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 255488.0
If we take 8 away from 8, we end up 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.

Let's proceed to step 7:
1 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 255488.0
Subtracting 0 from 0 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.

On to step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 255488.0
Deduct 0 from 0 and we're left 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.

The final outcome is 255488.0, with a leftover of 0.0.
