490685 divided by 2 
We want to figure out the number of times 490685 can be divided by 2.

Moving on to step 1:
2 can be fit into 4 2 times, resulting in 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

On to step 2:
When dividing 9 by 2, we get 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
If we subtract 8 from 9, we get 1.
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.
Record the quotient 5 as the next digit in the result. 
Result so far: 245.0
Subtracting 10 from 10 leaves us with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 2

Moving on to step 4:
2 goes into 6 3 times with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 2453.0
If we subtract 6 from 6, we get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 2

Step 5:
If we divide 8 by 2, we get 4 and a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 24534.0
Subtract 8 from 8 to get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 2

Let's proceed to step 6:
The number 2 fits into 5 2 times, leaving a remainder of 1.
The next digit of our result is 2. 
Result so far: 245342.0
Subtracting 4 from 5 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
2 can be fit into 10 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 245342.5
If we take 10 away from 10, 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.

Going ahead to step 8:
0 divided by 2 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 245342.5
Subtract 0 from 0 to 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 9:
2 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 245342.5
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 245342.5, with a leftover of 0.0.
