We're dividing 805039 by 2 
The aim is to understand the frequency of 2 in 805039.

Let's proceed to step 1:
2 goes into 8 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 8 from 8 leaves us with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 2

Going ahead to step 2:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 40.0
Subtracting 0 from 0 leaves us with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 2

Advancing to step 3:
When dividing 5 by 2, we get 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 402.0
The remainder is 1 after subtracting 4 from 5.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 2

Step 4:
If we divide 10 by 2, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 4025.0
Deduct 10 from 10 and we're left with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 2

Moving on to step 5:
If we divide 3 by 2, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 40251.0
Subtracting 2 from 3 leaves us with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 2

On to step 6:
The number 2 fits into 19 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 402519.0
Subtracting 18 from 19 leaves us 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.

Advancing 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: 402519.5
The remainder is 0 after subtracting 10 from 10.
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 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 402519.5
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.

Let's proceed to step 9:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 402519.5
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.

In conclusion, the division gives 402519.5 with a balance of 0.0.
