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.

Not always. 8 ÷ 2 = 4 14 ÷ 7 = 2

A prime number is a number that is only evenly divisible by 1 and itself, since 11 and 17 both divide equally (no remainder) into 187 - it is not prime.

A prime number is a number that only has two factors. That is, it can only divide evenly (without leaving a remainder) by 1 and itself. 21 can divide by 3 to give 7. Therefore it has more factors than just 1 and itself. Thus twenty-one is not a member of the prime number set.

Divide it by each prime number which does not have remainder.

To find a prime factor of a number, divide by 2 and see if you get no remainder. Then divide by 3, 4, 5, and so on, until one of the numbers you try gets you no remainder. If no such numbers work below the number you chose, it is prime. In the case of the number 9, 2 does not go into 9, but 3 does.

With exception of '2' all prime numbers are odd. Any odd number that ends in '5' is not a prime. Any number that ends in 0,2,4,6,8 are even and not primes. '9' is a composite number and not a prime. So you are left with 3 or 7 , which are primes. So taking a number , say '23' divide by '3' leaves a remainder of '2' so it is a prime. Similarly '23' divided by '7' leaves a remainder of '2' so 23 is a prime. If No remainder is left then the number is composite and not a prime. e.g. 4567 is it a prime ? Its odd so could be a prime Does it divide by '3' answer 1522 remainder '1' so it is a prime. Try '7' answer 652 remainder '3' it is a prime. Hence 4567 is a definite prime number.

you have to divide the remainder by the number you are dividing

Since 5 is a prime number only the numbers 1 and 5 divide it without a remainder.

When you divide 24 by 7 the remainder is 3.

Your question's meaning eludes me. You can divide any number by 5, whether or not it is a remainder, and why would you want to divide a remainder by 5 anyway?
