We look at the division of 855913 by 2 
The aim is to understand the frequency of 2 in 855913.

Step 1:
The number 2 fits into 8 4 times, leaving a remainder of 0.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 8 from 8 and we're left with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 2

Advancing to step 2:
If we divide 5 by 2, we get 2 and a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 42.0
The remainder is 1 after subtracting 4 from 5.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 2

Moving on to step 3:
2 can be fit into 15 7 times, resulting in a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 427.0
Deduct 14 from 15 and we're left with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 2

On to step 4:
2 can be fit into 19 9 times, resulting in a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 4279.0
If we subtract 18 from 19, we get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 2

Step 5:
When dividing 11 by 2, we get 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 42795.0
Subtracting 10 from 11 leaves us with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 2

Step 6:
The number 2 fits into 13 6 times, leaving a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 427956.0
If we subtract 12 from 13, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
10 divided by 2 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 427956.5
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.

Moving on to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 427956.5
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.

Going ahead to step 9:
2 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 427956.5
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.

In conclusion, the division gives 427956.5 with a balance of 0.0.
