5 / 7 is 0.71, true.
But that's just division.
7 does not go into 5, so 5 is what's left over.
Think of it as whole number division:
7 / 5 = 0.
Remaining: 5
Even for decimals:
7 % 2.5
7 / 2.5 = 2.
Remaining: 2
(7 - 5 = 2, 2.5 does not go into 2)

Woops I read the question backwards lol.
(Disregard what I said previously)
7 Does NOT go into 5.
Therefore, the remainder is 5.
5 / 7 < 1.

I keep it in my mind like this 5/7 = how many 7s are there in 5 ? none right ? so 5 remaining .. so the answer is 5

5 is less than 7, so the answer is 5?

Yes.
For example if I had 8 % 7.
7 goes into 8 once.
The remainder is 1:
8 - 7 = 1.
If I had 15 % 7.
7 goes into 15 twice.
The remainder is 1.
15 - 7 = 8.
8 - 7 = 1.
You can also think of it as floor division. (But keeping track of the remainder)
15 / 7 = 2.
Remainder: 1.
PS: sorry about writing that stuff backwards, fixed my original, hopefully it makes sense now. Having a brain fart day. 😜

The result of a% b is the remainder of dividing a by b, that is, 5/7 will be 0.71. Why answer 5?
