We look at the division of 498986 by 2 
We want to figure out the number of times 498986 can be divided by 2.

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

Advancing to step 2:
2 goes into 9 4 times with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Subtracting 8 from 9 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 2

Going ahead to step 3:
2 goes into 18 9 times with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 249.0
The remainder is 0 after subtracting 18 from 18.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 2

On to step 4:
When dividing 9 by 2, we get 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 2494.0
The remainder is 1 after subtracting 8 from 9.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 2

Moving on to step 5:
2 goes into 18 9 times with a remainder of 0.
The next digit of our result is 9. 
Result so far: 24949.0
Subtracting 18 from 18 leaves us with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 2

Going ahead to step 6:
2 can be fit into 6 3 times, resulting in a remainder of 0.
The next digit of our result is 3. 
Result so far: 249493.0
Subtract 6 from 6 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.

Step 7:
0 divided by 2 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 249493.0
If we take 0 away from 0, 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.

Let's proceed to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 249493.0
If we take 0 away from 0, 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.

The final result is 249493.0 with a remainder of 0.0.
