We divide 851735 by 2
The aim is to understand the frequency of 2 in 851735.

Advancing to step 1:
When dividing 8 by 2, we get 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 8 from 8 to get 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 2

Going ahead to step 2:
2 can be fit into 5 2 times, resulting in a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 42.0
Deduct 4 from 5 and we're left with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 2

Step 3:
When dividing 11 by 2, we get 5 with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 425.0
The remainder is 1 after subtracting 10 from 11.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 2

Let's proceed to step 4:
When dividing 17 by 2, we get 8 with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 4258.0
Subtract 16 from 17 to get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 2

Advancing to step 5:
If we divide 13 by 2, we get 6 and a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 42586.0
Subtract 12 from 13 to get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 2

Step 6:
If we divide 15 by 2, we get 7 and a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 425867.0
The remainder is 1 after subtracting 14 from 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
If we divide 10 by 2, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 425867.5
If we take 10 away from 10, 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.

Step 8:
0 divided by 2 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 425867.5
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.

Step 9:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 425867.5
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.

In conclusion, the division gives 425867.5 with a balance of 0.0.
