Tracert works by sending a series of packets to determine the routing hops between where you are and the destination address you specify. It does this by sending a series of ICMP echo requests to the far end. The first attempt has the TTL in the packet set to 1. The first router on the path decrements this to 0 and therefore cannot forward the packet, so it (the router) sends back a TTL exceeded message. Thus the router's IP address is discovered. Tracert then repeats the exercise but with a TTL of 2. The first router passes this, decrementing the TTL to 1, but the second router cannot forward the packet so sends back a TTL exceeded, revealing its address. And so on until either the destination is reached or you exceed the maximum number of hops that tracert is configured to allow.
Each line of output corresponds to one iteration of the TTL as explained above. The reason you see three times on each line is that each 'step' is tried three times, giving you three round-trip time figures for each hop along the route
