685168 divided by 2 
The aim is to understand the frequency of 2 in 685168.

Going ahead to step 1:
6 divided by 2 is 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 6 away from 6, we end up with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 2

Advancing to step 2:
The number 2 fits into 8 4 times, leaving a remainder of 0.
The next digit of our result is 4. 
Result so far: 34.0
Subtracting 8 from 8 leaves us with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 2

Step 3:
If we divide 5 by 2, we get 2 and a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 342.0
Subtract 4 from 5 to get 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 2

Let's proceed to step 4:
If we divide 11 by 2, we get 5 and a remainder of 1.
The next digit of our result is 5. 
Result so far: 3425.0
Subtract 10 from 11 to get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 2

Advancing to step 5:
When dividing 16 by 2, we get 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 34258.0
Subtracting 16 from 16 leaves us with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 2

Advancing to step 6:
2 goes into 8 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 342584.0
Deduct 8 from 8 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.

Step 7:
0 divided by 2 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 342584.0
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.

Moving on to step 8:
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: 342584.0
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.

After the division, we end up with 342584.0 and a remainder of 0.0.
