We look at the division of 742566 by 2 
The aim is to understand the frequency of 2 in 742566.

Advancing to step 1:
7 divided by 2 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 1 after subtracting 6 from 7.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 2

Moving on to step 2:
2 can be fit into 14 7 times, resulting in a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Subtracting 14 from 14 leaves us with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 2

Going ahead to step 3:
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: 371.0
If we subtract 2 from 2, we get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 2

Advancing to step 4:
The number 2 fits into 5 2 times, leaving a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 3712.0
Deduct 4 from 5 and we're left with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 2

Step 5:
2 goes into 16 8 times with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 37128.0
Subtracting 16 from 16 leaves us with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 2

On to step 6:
2 can be fit into 6 3 times, resulting in a remainder of 0.
The next digit of our result is 3. 
Result so far: 371283.0
The remainder is 0 after subtracting 6 from 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
If we divide 0 by 2, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 371283.0
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.

On to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 371283.0
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.

In conclusion, the division gives 371283.0 with a balance of 0.0.
