When sharing say 'sweets' , between friends. Rather than saying 'one for yoiu and one for me'. etc.,
You divide the total number of sweets , between the total number of recipients.
So if you have 98 sweets in a bag and '7' recipients, then instead of saying 'one for you etc', very tedious, you say 98 / 7 = 14 . So each recipient received 14 sweets. DONE!!!!!

Divide and conquer is computer science. It is an important algorithm design.
why is it important to know how to multiply
Divide untitl it is no longer able to divide, that would equal to 40/60 or 40/100
You divide the number by 2. If the number is able to divide WITHOUT a remainder, then it is a prime number. If you divide a number by 1, you will get the same number. That is not a prime number.
Because you can know if your answer will be a whole number when you divide.
