Splitting a comma seperated value into multiple columns using SQL View

I have a table that looks something like this:

Column1 Column2 Column3
John 12, 34, 5,498 Texas
Mike 16, 8, 69, 54 New York
Robert 104, 42, 110 Mexico
Josh 25 Maine


I am trying to seperate the values in Column2 into multiple columns that hold single values so that for instance the first row's Column2 holds each value in a different Column:
Column1 Column2 Column3 Column4
12 34 5 498

Basically I am trying to normalize the data and without doing this, I cannot move forward. I would really appreciate if someone can help me solve this using some sort of SQL Query in Access's SQL View.

Thanks in advance!

how are you importing the data into the table? What is the data source?
