People will make fun of you but you may not be trolling. To divide you take the first number, in your case five, and see how many times it goes into the other number, which is five times
To divide you are seeing how many times a number can fit into another one. So in your case you are trying to find how many times the number 5 can fit into the number 25. So you start with 25.
1) 25-5=20
2)20-5=15
3)15-5=10
4)10-5=5
5)5-5=0
So as you can see 5 can fit into 25 exactly 5 times.
