Let's divide 409458 by 2
The aim is to understand the frequency of 2 in 409458.

Moving on to step 1:
2 goes into 4 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 4 from 4 to get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 2

Advancing to step 2:
0 divided by 2 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we take 0 away from 0, we end up with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 2

Going ahead to step 3:
The number 2 fits into 9 4 times, leaving a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 204.0
The remainder is 1 after subtracting 8 from 9.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 2

Moving on to step 4:
If we divide 14 by 2, we get 7 and a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 2047.0
If we subtract 14 from 14, we get 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 2

Let's proceed to step 5:
2 can be fit into 5 2 times, resulting in a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 20472.0
If we subtract 4 from 5, we get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 2

Let's proceed to step 6:
2 goes into 18 9 times with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 204729.0
Deduct 18 from 18 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.

Let's proceed to step 7:
2 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 204729.0
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.

Advancing to step 8:
2 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 204729.0
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.

After the division, we end up with 204729.0 and a remainder of 0.0.
