Source Code Character Frequency code-golf

Write a program using SBCS that get a single byte character as an input and prints the frequency of that character in the program's source code (percentage format) as an output.

Example:

Assuming my program is: ab#cd%b then the output of the program should be:

input output ----- ------ a 14.29% b 28.57% # 14.29% c 14.29% d 14.29% % 14.29% 

Notes:

• Output must be in percentage format.
• Printed value must be with 2 digits after decimal (Print 15.00%, not 15%. print 15.12%, not 15.12345%).
• You man trim the rest of the digits after decimal in any way you want (ceiling, round, floor, simple trimming, ...)

Scoring:

This is code-golf - the shortest code wins.

Source Code Byte Frequency - Posted here

Changes from the original idea:

• Without the requirement of fixed representation of the result (percentage and trimming).
• With constraint: source code must be at least 1 byte long
• Changed from character to byte, plus removing the constraint of SBCS languages only.
