Cambridge Dictionary gave the following rules that will help us learn how to use “each” and “every”
We use each to refer to individual things in a group or a list of two or more things. It is often similar in meaning to every, but we use every to refer to a group or list of three or more things.
1. We use adverbs such as almost, practically and nearly with every, but not with each.
Ex. Almost every car in the car park was new.
2. We can use each of + pronoun or each of + determiner + noun, but with every we must use every one + pronoun or every one + determiner + noun.
Ex. Each of us has a bicycle.
