We look at the division of 869799 by 2 
The aim is to understand the frequency of 2 in 869799.

Step 1:
8 divided by 2 is 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 8 from 8, we get 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 2

Let's proceed to step 2:
If we divide 6 by 2, we get 3 and a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 43.0
If we subtract 6 from 6, we get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 2

Moving on to step 3:
When dividing 9 by 2, we get 4 with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 434.0
If we take 8 away from 9, we end up with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 2

Let's proceed to step 4:
The number 2 fits into 17 8 times, leaving a remainder of 1.
The next digit of our result is 8. 
Result so far: 4348.0
Deduct 16 from 17 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 2

Going ahead to step 5:
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: 43489.0
If we take 18 away from 19, we end up with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 2

On to step 6:
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: 434899.0
Subtract 18 from 19 to 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.

Going ahead to step 7:
The number 2 fits into 10 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 434899.5
Subtract 10 from 10 to 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.

Moving on to step 8:
When dividing 0 by 2, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 434899.5
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.

Step 9:
0 divided by 2 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 434899.5
Subtract 0 from 0 to 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.

After the division, we end up with 434899.5 and a remainder of 0.0.
