496421 ÷ 2 
Let's see how many times 2 fits into 496421.

On to step 1:
If we divide 4 by 2, we get 2 and a remainder of 0.
Put 2 as the next digit of the answer. 
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

Let's proceed to step 2:
When dividing 9 by 2, we get 4 with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Deduct 8 from 9 and we're left with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 2

Going ahead to step 3:
16 divided by 2 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 248.0
The remainder is 0 after subtracting 16 from 16.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 2

On to step 4:
2 can be fit into 4 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 2482.0
If we take 4 away from 4, we end up with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 2

On to step 5:
2 can be fit into 2 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 24821.0
Subtract 2 from 2 to get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 2

Let's proceed to step 6:
The number 2 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 248210.0
If we subtract 0 from 1, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
If we divide 10 by 2, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 248210.5
The remainder is 0 after subtracting 10 from 10.
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:
If we divide 0 by 2, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 248210.5
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.

Step 9:
0 divided by 2 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 248210.5
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.

After the division, we end up with 248210.5 and a remainder of 0.0.
