We pick l.root-servers.net, one of the 13 root servers (1), and ask it about hotmail.co.jp and learn that jp is delegated to seven name servers (2), so we ask c.dns.jp where we learn that hotmail.co.jp is delegated to three name servers, including ns3.msft.net (3), so we ask that one and get the following answer:
