How do i divide? : -)i nevered learned

Division is very simple don't worry. division is the opposite of multiplication.
if i wanted to share 12 cookies with 6 people, i would want to share it evenly.
12 divided 6 = 2 cookies per person

now back to division being the opposite of multiplying. note how 12 divided by 6 = 2, right? well, read that backwards.
2 x 6 = 12. it isn't a coincidence!
now, let's try something different.
i have 8 cookies. i want to split them evenly with a friend. how many do we each get?
8 divided by 2
answer below

4

This is what I do if it was 10 divided by 2 it will be 5 because 2 could fit into 10 five times right?So the answer will be 5...

I'm pretty sure it's b). i try drawing the functions out and b is the one that stands out or isnt a "line"
