Result so far: 4.0
If we subtract 8 from 8, we get 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 2

Let's proceed to step 2:
If we divide 5 by 2, we get 2 and a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Subtract 4 from 5 to get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 2

Advancing to step 3:
2 can be fit into 10 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 425.0
Subtracting 10 from 10 leaves us with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 2

Going ahead to step 4:
The number 2 fits into 7 3 times, leaving a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 4253.0
Subtracting 6 from 7 leaves us with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 2

On to step 5:
When dividing 17 by 2, we get 8 with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 42538.0
Subtract 16 from 17 to get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 2

Advancing to step 6:
If we divide 11 by 2, we get 5 and a remainder of 1.
The next digit of our result is 5. 
Result so far: 425385.0
The remainder is 1 after subtracting 10 from 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
When dividing 10 by 2, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 425385.5
If we subtract 10 from 10, 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.

On to step 8:
2 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 425385.5
The remainder is 0 after subtracting 0 from 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:
0 divided by 2 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 425385.5
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.

Our division results in 425385.5 with a remaining 0.0.
