We're dividing 12991929 by 2 
The aim is to understand the frequency of 2 in 12991929.

On to step 1:
If we divide 1 by 2, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 2

Going ahead to step 2:
2 goes into 12 6 times with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 12 from 12 leaves us with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 2

Let's proceed to step 3:
2 goes into 9 4 times with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 64.0
If we subtract 8 from 9, we get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 2

Moving on to step 4:
19 divided by 2 is 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 649.0
Subtract 18 from 19 to get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 2

Going ahead to step 5:
The number 2 fits into 11 5 times, leaving a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 6495.0
If we subtract 10 from 11, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 2

Moving on to step 6:
If we divide 19 by 2, we get 9 and a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 64959.0
Subtracting 18 from 19 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 2

Going ahead to step 7:
2 can be fit into 12 6 times, resulting in a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 649596.0
Deduct 12 from 12 and we're left with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 2

Step 8:
9 divided by 2 is 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 6495964.0
Subtracting 8 from 9 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 9:
If we divide 10 by 2, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 6495964.5
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.

Let's proceed to step 10:
2 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6495964.5
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.

Advancing to step 11:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 6495964.5
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.

In conclusion, the division gives 6495964.5 with a balance of 0.0.
