Moving on to step 1:
The number 2 fits into 4 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 4 away from 4, we end up with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 2

On to step 2:
5 divided by 2 is 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 22.0
The remainder is 1 after subtracting 4 from 5.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 2

On to step 3:
10 divided by 2 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 225.0
Subtract 10 from 10 to get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 2

On to step 4:
The number 2 fits into 2 1 times, leaving a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 2251.0
The remainder is 0 after subtracting 2 from 2.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 2

Advancing to step 5:
The number 2 fits into 8 4 times, leaving a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 22514.0
If we take 8 away from 8, we end up with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 2

On to step 6:
7 divided by 2 is 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 225143.0
The remainder is 1 after subtracting 6 from 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
10 divided by 2 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 225143.5
Deduct 10 from 10 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.

Let's proceed to step 8:
If we divide 0 by 2, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 225143.5
If we subtract 0 from 0, 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 9:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 225143.5
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.

The final outcome is 225143.5, with a leftover of 0.0.
