number of occurrences in csv files

Hello mathworkers,

I have the attached data, and I want to apply this pseducode below on the data, all the data are numeric and in each column I want to know how many times the 1 is repeated, and how many times the 2 is repeated or any other numbers, please if any one could help

1. For each features do (all co,umn are numeric)
2. Calculate number of different occurrence in each feature
3. If one of the occurrence is repeated less than 10 % of the whole data, then remove it
4. The output is number of occurrence for each column after removing the occurrence with less than 10% repeated
