We divide 446919 by 2
The aim is to understand the frequency of 2 in 446919.

Let's proceed to step 1:
If we divide 4 by 2, we get 2 and a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
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

Moving on to step 2:
If we divide 4 by 2, we get 2 and a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we subtract 4 from 4, we get 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 2

Moving on to step 3:
2 goes into 6 3 times with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 223.0
Deduct 6 from 6 and we're left with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 2

On to step 4:
2 goes into 9 4 times with a remainder of 1.
The next digit of our result is 4. 
Result so far: 2234.0
If we subtract 8 from 9, we get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 2

Advancing to step 5:
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: 22345.0
Subtracting 10 from 11 leaves us with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 2

Going ahead to step 6:
2 can be fit into 19 9 times, resulting in a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 223459.0
Deduct 18 from 19 and we're left 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.

Let's proceed to step 7:
10 divided by 2 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 223459.5
If we subtract 10 from 10, 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.

On to step 8:
0 divided by 2 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 223459.5
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:
When dividing 0 by 2, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 223459.5
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 223459.5, with a leftover of 0.0.
