We're dividing 240297 by 2 
Let's see how many times 2 fits into 240297.

Going ahead to step 1:
The number 2 fits into 2 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 0 after subtracting 2 from 2.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 2

Advancing to step 2:
If we divide 4 by 2, we get 2 and a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 4 from 4, we get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 2

On to step 3:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 120.0
Deduct 0 from 0 and we're left with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 2

On to step 4:
If we divide 2 by 2, we get 1 and a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1201.0
The remainder is 0 after subtracting 2 from 2.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 2

Let's proceed to step 5:
The number 2 fits into 9 4 times, leaving a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 12014.0
Subtracting 8 from 9 leaves us with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 2

Step 6:
When dividing 17 by 2, we get 8 with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 120148.0
Deduct 16 from 17 and we're left 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.

Advancing to step 7:
The number 2 fits into 10 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 120148.5
If we subtract 10 from 10, we 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.

Let's proceed to step 8:
0 divided by 2 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 120148.5
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.

Going ahead to step 9:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 120148.5
If we subtract 0 from 0, we 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 120148.5 and a remainder of 0.0.
