We look at the division of 810247 by 2 
The aim is to understand the frequency of 2 in 810247.

Advancing to step 1:
8 divided by 2 is 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 0 after subtracting 8 from 8.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 2

Advancing to step 2:
2 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 40.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 2

Let's proceed to step 3:
10 divided by 2 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 405.0
If we subtract 10 from 10, we get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 2

Moving on to step 4:
2 goes into 2 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 4051.0
Subtracting 2 from 2 leaves us with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 2

Let's proceed to step 5:
The number 2 fits into 4 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 40512.0
Subtract 4 from 4 to get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 2

Going ahead to step 6:
7 divided by 2 is 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 405123.0
If we subtract 6 from 7, 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.

Let's proceed to step 7:
The number 2 fits into 10 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 405123.5
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.

Let's proceed to step 8:
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: 405123.5
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.

Going ahead to step 9:
When dividing 0 by 2, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 405123.5
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.

The final outcome is 405123.5, with a leftover of 0.0.
