Hi there @Daniiltje,
I believe it's possible. But you'll need to enlighten me on what you want to achieve exactly i.e where you want to display the Div? On all collections pages? or a specific collection page?
Anyways, you can do so if you are comfortable with Liquid, HTML, and CSS code. You'll need to add an if condition to check if the product is the 5th from the queue and then add the div HTML element along with some styling as per your requirements.
Hope it helps.
