We divide 690661 by 2
The aim is to understand the frequency of 2 in 690661.

Going ahead to step 1:
2 goes into 6 3 times with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 0 after subtracting 6 from 6.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 2

On to step 2:
The number 2 fits into 9 4 times, leaving a remainder of 1.
The next digit of our result is 4. 
Result so far: 34.0
If we subtract 8 from 9, we get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 2

Advancing to step 3:
If we divide 10 by 2, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 345.0
Subtract 10 from 10 to get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 2

Going ahead to step 4:
The number 2 fits into 6 3 times, leaving a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3453.0
The remainder is 0 after subtracting 6 from 6.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 2

Moving on to step 5:
2 can be fit into 6 3 times, resulting in a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 34533.0
Deduct 6 from 6 and we're left with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 2

Step 6:
When dividing 1 by 2, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 345330.0
Subtract 0 from 1 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
2 goes into 10 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 345330.5
If we take 10 away from 10, 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:
0 divided by 2 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 345330.5
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.

Let's proceed to step 9:
0 divided by 2 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 345330.5
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.

In conclusion, the division gives 345330.5 with a balance of 0.0.
