86449 divided by 2 
The aim is to understand the frequency of 2 in 86449.

Let's proceed to step 1:
When dividing 8 by 2, we get 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 8 from 8 leaves us with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 2

Moving on to step 2:
2 goes into 6 3 times with a remainder of 0.
The next digit of our result is 3. 
Result so far: 43.0
If we take 6 away from 6, we end up with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 2

Going ahead to step 3:
2 goes into 4 2 times with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 432.0
If we subtract 4 from 4, we get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 2

Moving on to step 4:
4 divided by 2 is 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 4322.0
If we subtract 4 from 4, we get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 2

Going ahead to step 5:
The number 2 fits into 9 4 times, leaving a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 43224.0
Deduct 8 from 9 and we're left 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.

Moving on to step 6:
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: 43224.5
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.

Moving on to step 7:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 43224.5
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.

Moving on to step 8:
0 divided by 2 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 43224.5
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.

After the division, we end up with 43224.5 and a remainder of 0.0.
