If SPF fails but DKIM does not, how does DMARC validate?

DMARC validation

DMARC only requires either SPF or DKIM to pass and align in order for DMARC to validate a valid email.  If you send via a third party and your emails are forwarded the chances are that your emails will fail SPF but DKIM will pass. 

SPF will not survive forwarding but DKIM will.
