We divide 86600575 by 2
The aim is to understand the frequency of 2 in 86600575.

Advancing 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
If we take 8 away from 8, we end up with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 2

Advancing to step 2:
6 divided by 2 is 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Deduct 6 from 6 and we're left with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 2

Going ahead to step 3:
2 goes into 6 3 times with a remainder of 0.
The next digit of our result is 3. 
Result so far: 433.0
Deduct 6 from 6 and we're left with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 2

Advancing to step 4:
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: 4330.0
If we take 0 away from 0, we end up with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 2

Step 5:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 43300.0
Subtracting 0 from 0 leaves us with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 2

Moving on to step 6:
5 divided by 2 is 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 433002.0
Subtract 4 from 5 to get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 2

Advancing to step 7:
2 can be fit into 17 8 times, resulting in a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 4330028.0
The remainder is 1 after subtracting 16 from 17.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 2

Let's proceed to step 8:
2 can be fit into 15 7 times, resulting in a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 43300287.0
If we subtract 14 from 15, 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.

Moving on to step 9:
If we divide 10 by 2, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 43300287.5
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.

Advancing to step 10:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 43300287.5
Deduct 0 from 0 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.

Going ahead to step 11:
When dividing 0 by 2, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 43300287.5
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.

The quotient of the division is 43300287.5, and the remainder is 0.0.
