ELI5: at what point does electricity stop in water?

Obviously if we put live electricity in the sea, the whole ocean wouldn’t then become dangerous with it. At what point does the electricity stop? What stops it?

Depends on how you "put electricity" in.

When lightning hits the ocean, it can more or less flow in any direction through the water, and the power dissipates accordingly. 

Just think of it expanding (hemi)spherically from the point it hits: the further it gets, the larger the area it covers becomes. The larger the area gets, the smaller the current per area becomes, until it is not noticeable any more.
