We look at the division of 280425 by 1 
We want to figure out the number of times 280425 can be divided by 1.

Let's proceed to step 1:
The number 1 fits into 2 2 times, leaving a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 2 from 2 leaves us with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 1

Advancing to step 2:
1 can be fit into 8 8 times, resulting in a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
If we subtract 8 from 8, we get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

Advancing to step 3:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 280.0
Deduct 0 from 0 and we're left with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

Going ahead to step 4:
1 goes into 4 4 times with a remainder of 0.
The next digit of our result is 4. 
Result so far: 2804.0
Subtract 4 from 4 to get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 1

Step 5:
If we divide 2 by 1, we get 2 and a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 28042.0
The remainder is 0 after subtracting 2 from 2.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 1

Moving on to step 6:
1 can be fit into 5 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 280425.0
If we take 5 away from 5, 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:
0 divided by 1 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 280425.0
If we take 0 away from 0, 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.

Advancing to step 8:
1 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 280425.0
If we take 0 away from 0, 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.

The final outcome is 280425.0, with a leftover of 0.0.
