실례합니다 Literally means "Excuse me"
so you can use it whenever you want to be excused
여기(요) -> 여기 means 'here' but you can use it in diverse context.
1) saying "Here it is" -> 자, 여기 있어요 -> 자, 여기요
2) when directing the place "Here" -> 여기요
2-1) telling that you are "I am here" -> 여기요.
3) when calling others "Look here" -> 여기요
*Like former teacher said, 여기요 can be used together with 실례합니다. but it is usually used itself
Thank so much, teachers.
It was so helpful to me.
