We look at the division of 610859 by 2 
The aim is to understand the frequency of 2 in 610859.

On to step 1:
6 divided by 2 is 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 6 from 6 and we're left with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 2

Let's proceed to step 2:
2 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 30.0
If we take 0 away from 1, we end up with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 2

Step 3:
10 divided by 2 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 305.0
Subtracting 10 from 10 leaves us with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 2

Moving on to step 4:
If we divide 8 by 2, we get 4 and a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 3054.0
Subtract 8 from 8 to get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 2

Step 5:
When dividing 5 by 2, we get 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 30542.0
Deduct 4 from 5 and we're left with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 2

Step 6:
When dividing 19 by 2, we get 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 305429.0
If we take 18 away from 19, we end up 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.

Going ahead to step 7:
2 can be fit into 10 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 305429.5
Deduct 10 from 10 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 8:
0 divided by 2 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 305429.5
The remainder is 0 after subtracting 0 from 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 9:
2 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 305429.5
The remainder is 0 after subtracting 0 from 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 305429.5 and a remainder of 0.0.
