We look at the division of 663217 by 2 
Let's see how many times 2 fits into 663217.

On to step 1:
The number 2 fits into 6 3 times, leaving a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 6 from 6, we get 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 2

Step 2:
When dividing 6 by 2, we get 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
Subtracting 6 from 6 leaves us with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 2

Advancing to step 3:
2 goes into 3 1 times with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 331.0
Subtracting 2 from 3 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 2

Let's proceed to step 4:
2 goes into 12 6 times with a remainder of 0.
The next digit of our result is 6. 
Result so far: 3316.0
If we subtract 12 from 12, we get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 2

On to step 5:
When dividing 1 by 2, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 33160.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 2

Let's proceed to step 6:
2 can be fit into 17 8 times, resulting in a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 331608.0
The remainder is 1 after subtracting 16 from 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
10 divided by 2 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 331608.5
Subtracting 10 from 10 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.

Step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 331608.5
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.

On to step 9:
0 divided by 2 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 331608.5
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.

In conclusion, the division gives 331608.5 with a balance of 0.0.
