s = "JINSAL0056(  1), JINSAL0057(  1), JINSAL0041(  1)"
res = s.split(', ').map{|line| line.chop.split('(  ')}
p res # [["JINSAL0056", "1"], ["JINSAL0057", "1"], ["JINSAL0041", "1"]]

res.each do |jinsal, number|
  puts "Do something with #{jinsal} and #{number}"
end

I think you can try. (Not the best way of course.)

yourstring = "JINSAL0056(  1), JINSAL0057(  1), JINSAL0041(  1),"
yourstring.split(/(\w+)\(\s*(\d)\)[,\s*]/)

Result will be 

["", "JINSAL0056", "1", " ", "JINSAL0057", "1", " ", "JINSAL0041", "1"]

but I recommended to use scan(//) 

yourstring.scan(/(\w+)\(\s*(\d)\)[,\s*]/)

Result will be

[["JINSAL0056", "1"], ["JINSAL0057", "1"], ["JINSAL0041", "1"]]

to assign variable you can loop like this

yourstring.scan(/(\w+)\(\s*(\d)\)[,\s*]/).each do |a,b|
     puts "#{a} #{b}"
end

You can pass regexes to split too:

foo = "JINSAL0056(  1), JINSAL0057(  1), JINSAL0041(  1),"
foo.split(/[\(\),\s]+/)

The result:

["JINSAL0056", "1", "JINSAL0057", "1", "JINSAL0041", "1"]

And make it into a hash:

Hash[*foo.split(/[\(\),\s]+/)]

Which will give you:

{"JINSAL0056"=>"1", "JINSAL0057"=>"1", "JINSAL0041"=>"1"}
