Create Module That Split Payments Dinamically

[rokity]

Hi. I need to split a payments in two payments: first is chosen from user , the second is PayPal or Stripe . The division of cost is calculated from an attribute on database. A simple , real example is this: the admin user create a product and set the cost, when a user buys this product he chooses the credit card, a section of cost go to the store the rest to on Paypal or Stripe card according to a percentage calculated from an attribute on DB.
There is a way to do this? Already exist a module for this? Or I need to create a payment module and what to do inside the module?

Thank
