We're dividing 491521 by 2 
We want to divide 491521 by 2.

Moving on to step 1:
When dividing 4 by 2, we get 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 0 after subtracting 4 from 4.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 2

Advancing to step 2:
9 divided by 2 is 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 24.0
The remainder is 1 after subtracting 8 from 9.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 2

Advancing to step 3:
11 divided by 2 is 5 with a remainder of 1.
The next digit of our result is 5. 
Result so far: 245.0
Deduct 10 from 11 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 2

Advancing to step 4:
15 divided by 2 is 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 2457.0
Deduct 14 from 15 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 2

Step 5:
The number 2 fits into 12 6 times, leaving a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 24576.0
Deduct 12 from 12 and we're left with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 2

Let's proceed to step 6:
2 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 245760.0
If we take 0 away from 1, we end up 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.

Let's proceed to step 7:
When dividing 10 by 2, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 245760.5
Subtracting 10 from 10 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 8:
0 divided by 2 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 245760.5
Deduct 0 from 0 and we're left 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.

Advancing to step 9:
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: 245760.5
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.

After the division, we end up with 245760.5 and a remainder of 0.0.
