How can we inject our custom APP code (html code) into shopify product page

[Vikas7819]

I'm trying to figure out how to get my app's html div onto the products page of shopify. I am creating an APP based on quantity breakdown feature using laravel. I need to add HTML code onto product page as shown below.

In right you can see the html code just above the ADD TO CART button. I need to do exactly same.

Please note that I am working with Laravel.

Thanks in advance!
