We look at the division of 605626 by 2 
The aim is to understand the frequency of 2 in 605626.

On to step 1:
The number 2 fits into 6 3 times, leaving a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 0 after subtracting 6 from 6.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 2

Going ahead to step 2:
0 divided by 2 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
Deduct 0 from 0 and we're left with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 2

On to step 3:
The number 2 fits into 5 2 times, leaving a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 302.0
If we subtract 4 from 5, we get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 2

Going ahead to step 4:
If we divide 16 by 2, we get 8 and a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 3028.0
The remainder is 0 after subtracting 16 from 16.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 2

Advancing to step 5:
2 goes into 2 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 30281.0
If we take 2 away from 2, we end up with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 2

Going ahead to step 6:
2 can be fit into 6 3 times, resulting in a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 302813.0
Subtract 6 from 6 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.

Step 7:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 302813.0
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.

Going ahead to 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: 302813.0
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.

The quotient of the division is 302813.0, and the remainder is 0.0.
