Let's divide 306449 by 2
The aim is to understand the frequency of 2 in 306449.

Going ahead to step 1:
2 goes into 3 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 2 from 3 to get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 2

Moving on to step 2:
2 goes into 10 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 10 from 10, we get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 2

Step 3:
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: 153.0
If we take 6 away from 6, we end up with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 2

On to step 4:
4 divided by 2 is 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 1532.0
Deduct 4 from 4 and we're left with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 2

Step 5:
If we divide 4 by 2, we get 2 and a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 15322.0
If we subtract 4 from 4, we get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 2

Step 6:
2 goes into 9 4 times with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 153224.0
If we take 8 away from 9, we end up 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.

Advancing to step 7:
2 goes into 10 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 153224.5
Subtracting 10 from 10 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.

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: 153224.5
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.

Advancing to step 9:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 153224.5
If we subtract 0 from 0, we 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.

The final outcome is 153224.5, with a leftover of 0.0.
