We look at the division of 415630 by 2 
The aim is to understand the frequency of 2 in 415630.

On to step 1:
2 can be fit into 4 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 4 from 4 to get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 2

Going ahead to step 2:
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: 20.0
If we subtract 0 from 1, we get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 2

Advancing to step 3:
15 divided by 2 is 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 207.0
Subtracting 14 from 15 leaves us with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 2

On to step 4:
When dividing 16 by 2, we get 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 2078.0
If we take 16 away from 16, we end up with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 2

On to step 5:
2 goes into 3 1 times with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 20781.0
Subtract 2 from 3 to get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 2

Advancing to step 6:
The number 2 fits into 10 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 207815.0
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.

Let's proceed to step 7:
When dividing 0 by 2, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 207815.0
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.

Moving on to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 207815.0
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.

The final outcome is 207815.0, with a leftover of 0.0.
