We divide 437168 by 2
The aim is to understand the frequency of 2 in 437168.

Advancing to step 1:
2 can be fit into 4 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 4 from 4 leaves us with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 2

On to step 2:
3 divided by 2 is 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtracting 2 from 3 leaves us with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 2

Let's proceed to step 3:
When dividing 17 by 2, we get 8 with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 218.0
If we take 16 away from 17, we end up with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 2

Advancing to step 4:
The number 2 fits into 11 5 times, leaving a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 2185.0
Deduct 10 from 11 and we're left with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 2

On to step 5:
The number 2 fits into 16 8 times, leaving a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 21858.0
Deduct 16 from 16 and we're left with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 2

Step 6:
8 divided by 2 is 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 218584.0
Subtract 8 from 8 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 7:
0 divided by 2 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 218584.0
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.

Going ahead to step 8:
2 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 218584.0
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.

In conclusion, the division gives 218584.0 with a balance of 0.0.
