We're dividing 243294 by 2 
The aim is to understand the frequency of 2 in 243294.

Going ahead to step 1:
The number 2 fits into 2 1 times, leaving a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 2 from 2 to get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 2

Let's proceed to step 2:
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: 12.0
Subtracting 4 from 4 leaves us with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 2

Going ahead to step 3:
If we divide 3 by 2, we get 1 and a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 121.0
The remainder is 1 after subtracting 2 from 3.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 2

Moving on to step 4:
2 goes into 12 6 times with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 1216.0
The remainder is 0 after subtracting 12 from 12.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 2

On to step 5:
2 can be fit into 9 4 times, resulting in a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 12164.0
The remainder is 1 after subtracting 8 from 9.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 2

Going ahead to step 6:
2 goes into 14 7 times with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 121647.0
If we take 14 away from 14, 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.

Moving on to step 7:
If we divide 0 by 2, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 121647.0
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 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 121647.0
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 121647.0 and a remainder of 0.0.
