Status Bar with several Stage

I would like to have some opinion on the design, I made to represent the product process QTY. At each stage, i should show to the user, how many of his requested product has been proceed. If there are other proposal, or way to improve current design.

1. First choice i made, is to represent the QTY in percentage to avoid having huge QTY number (such as 100 000 000 PCS)
2. I rather not using a mouse-hover to provide more details. Even i have a design with.
3. Size (Height/Wide) of the status bar is not changeable.

Thanks
