Does this sound natural in English?

A. Bind each number to a variable.

B. Bind each number to a separate variable

Context:

A variable is like a container in computer programming. It's like a drawer that holds something. We put something in them (numeric values, text strings, etc.) but the terms we us use are "bind" or "assign" instead of "put".

I have multiple numbers 2, 33, 4, 5, 29, 32 and each has a separate variable.

variable <= 2

variable2 <= 33

variable3 <= 4

I used "each". I'm not sure if that is okay or I should use "every" instead.
