We divide 490806 by 2
We want to figure out the number of times 490806 can be divided by 2.

Going ahead to step 1:
When dividing 4 by 2, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 4 from 4 to get 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 2

Step 2:
2 goes into 9 4 times with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 24.0
Subtract 8 from 9 to get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 2

Advancing to step 3:
The number 2 fits into 10 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 245.0
If we subtract 10 from 10, we get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 2

Step 4:
8 divided by 2 is 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 2454.0
Subtracting 8 from 8 leaves us with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 2

Step 5:
If we divide 0 by 2, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 24540.0
If we take 0 away from 0, we end up with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 2

Going ahead to step 6:
6 divided by 2 is 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 245403.0
Subtracting 6 from 6 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 7:
When dividing 0 by 2, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 245403.0
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 8:
When dividing 0 by 2, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 245403.0
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 245403.0 with a balance of 0.0.
