Packing $8$ identical DVDs into $5$ indistinguishable boxes I am trying to solve this question:

How many ways are there to pack eight identical DVDs into five indistinguishable boxes so that each box contains at least one DVD?

I am very lost at trying to solve this one. My attempt to start this problem involved drawing 5 boxes, and placing one DVD each, meaning 3 DVDs were left to be dropped, but I am quite stuck at this point.
Any help you can provide would be great. Thank you.

It is called stirling numbers.
 S(8,5)=1050 ways
