Filling the remaining width and height around a centered div

Question

Is it possible to fill the remaining screen space around div, located in the center like this:

Red divhas the following properties, since I would like to maintain the same aspect ratio and place it in the center of the screen:

position: absolute;
height: 80%;
width: auto;
top: 50%;
left: 50%;
margin-right: -50%;
transform: translate(-50%, -50%);

Is it possible to dynamically adjust 4 surrounding divs to fill the remaining space on the screen?

EDIT: red divis a transparent image
