We divide 640292 by 2
The aim is to understand the frequency of 2 in 640292.

Advancing to step 1:
When dividing 6 by 2, we get 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 6 from 6, we get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 2

Going ahead to step 2:
2 goes into 4 2 times with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
Subtract 4 from 4 to get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 2

Let's proceed to step 3:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 320.0
If we subtract 0 from 0, we get 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 2

Going ahead to step 4:
2 divided by 2 is 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 3201.0
If we take 2 away from 2, we end up with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 2

Step 5:
9 divided by 2 is 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 32014.0
If we subtract 8 from 9, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 2

On to step 6:
When dividing 12 by 2, we get 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 320146.0
If we take 12 away from 12, 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.

Advancing to step 7:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 320146.0
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.

Advancing to step 8:
2 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 320146.0
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 quotient of the division is 320146.0, and the remainder is 0.0.
