How to split a Single Column with multiple entries into multiple columns

I have a csv file with entries of multiple columns in a single column with multiple quotes. When I load it in R using data.table(fread) it appears as a table with quotes. I have tried using quote=FALSE, but it is not working.

Here's how it looks like

I also tried reading it using read.csv it appears as a single column with multiple entries.

I also tried using print.data.frame using quote=FALSE. But it is not working either.

So I have two problems:

1. How to split this single column into multiple and
2. How to remove these quotes

I will be grateful for your help.
