Yesss.
2 - 8 = -6 -6 is not a natural number. 2/8 = 1/4 1/4 is not a natural number.
You need to carry out the division. If the remainder is 0 then it is divisible, if not it is not. There are divisibility rules which can help with small or simple divisors but these are quite limited.

You do the division!
No, the natural numbers are not closed under division. For example, 2 and 3 are natural numbers, but 2/3 is not.
No. Closed means that you could do the operation (division) on any two natural numbers and you would get a result in the natural numbers. Take 7/3 for example, this is obviously not a natural number.
You can give hundreds of examples, but a single counterexample shows that natural numbers are NOT closed under subtraction or division. For example, 1 - 2 is NOT a natural number, and 1 / 2 is NOT a natural number.
Yesss.
Historically and even geographically the Vindhyas are acting as a natural division dividing North from South India.

uhm.. there are two types of science: social and natural
A fissure is a groove, natural division, deep furrow or elongated cleft.
2 - 8 = -6 -6 is not a natural number. 2/8 = 1/4 1/4 is not a natural number.
Im just going to guess that its a boundary that nature provided, but and example is an ocean, a river, and a mountain.
