489920 ÷ 2 
We want to figure out the number of times 489920 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
Subtracting 4 from 4 leaves us with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 2

Let's proceed to step 2:
If we divide 8 by 2, we get 4 and a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
Subtract 8 from 8 to get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 2

Let's proceed to step 3:
2 goes into 9 4 times with a remainder of 1.
The next digit of our result is 4. 
Result so far: 244.0
Deduct 8 from 9 and we're left with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 2

Let's proceed to step 4:
If we divide 19 by 2, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 2449.0
Deduct 18 from 19 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 2

Advancing to step 5:
The number 2 fits into 12 6 times, leaving a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 24496.0
Subtract 12 from 12 to get 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 2

Let's proceed to step 6:
When dividing 0 by 2, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 244960.0
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.

Let's proceed to step 7:
When dividing 0 by 2, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 244960.0
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.

Let's proceed to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 244960.0
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.

After the division, we end up with 244960.0 and a remainder of 0.0.
