Take the body to a location you know is safe or unfrequented by people.

Get some kind of tub or container that can fit a body (break bones as neccessary to fit). Try to avoid having to cut the body up as that may leave blood/dna, etc. which can be found even after serious cleaning. Be as clean as you possibly can.

Fill tub with body with a good amount of lime or acid and wait for everything to dissolve.

This method is much more preferable than incineration as burning as will often leave teeth and bones and people can be identified via their dental records.

Dispose of any clothing worn during that time, all tools, vehicles, etc. Bleach all surfaces you can think of.

If you can get to the ocean quickly and have access to a boat with good range, get a steel drum and place the body inside with lime. Work out the buoyancy of the drum and add weights as necessary. Seal the drum.

Sail out a good distance from the shore to deep water and roll the drum overboard.

All too often, people panic when hiding bodies in the water and simply throw the body into the nearest river or lake where it can easily wash up mostly intact or can be found by divers scouring the bed.

This.
