243508 divided by 2 
The aim is to understand the frequency of 2 in 243508.

Step 1:
2 can be fit into 2 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 2 from 2, we get 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 2

Let's proceed to step 2:
The number 2 fits into 4 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 4 from 4 and we're left with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 2

Let's proceed to step 3:
3 divided by 2 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 121.0
The remainder is 1 after subtracting 2 from 3.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 2

Moving on to step 4:
The number 2 fits into 15 7 times, leaving a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 1217.0
The remainder is 1 after subtracting 14 from 15.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 2

Moving on to step 5:
10 divided by 2 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 12175.0
Subtract 10 from 10 to get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 2

Advancing to step 6:
2 can be fit into 8 4 times, resulting in a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 121754.0
The remainder is 0 after subtracting 8 from 8.
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 7:
When dividing 0 by 2, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 121754.0
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.

Moving on to step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 121754.0
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.

The final result is 121754.0 with a remainder of 0.0.
