Starry, I have 15 chocolates with me.

They have to be equally distribute it among five of my friends.

Will you help me to design how many chocolates each friends just  get?

Ok, let do it this way.
Let give one chocolate each for five of my friends here.

1 2 3 4 5,
now let give one once chocolates again.

Here, 1 2 3 4 5, 
some more chocolates left. 
So let us distribute these also.

1 2 3 4 5. 
Hey Starry see all chocolates are over.

How many chocolates are there in each group?
Yes, 3 chocolates.

So each of my friends will get 3 chocolates.

Here, 15 chocolates are divided into 5 groups of equal number of chocolates.

Each group has 3 chocolates.
So, they can also be written as 15 : 5 = 3.

Do you understand Starry?

When many things are to be divided equally into groups then we have to do division.

Hey Starry, observe the pictures here and fill in the boxes.

In the first picture, there are 9 flowers.

They are divided into 3 groups of 3 flowers each.

So we write it in the form of the vision as 9 : 3 = 3.

There are  total of 30 ice-cream cups.

They are divided into 5 groups with 4 cups in each group.

So there are 2 planes in each group. We write it as 6 : 3 = 2.

Here is the last picture, Starry.

12 sticks have been divided into 2 groups with 6 sticks in each group.

Write it information in the form of division Starry. 
Yes, we write it as 12 : 2 = 6.

Now let write a few example without using picture.

A set of 21 hairpins is divided into 3 groups with 7 pins in each group.

So 21 divided by 3 is equal to____.
Yes, 7.
