You can use String#split or a regex depending on the requirements:

irb(main):001:0> parts = "Test Part 123 G 477".split(" ")
=> ["Test", "Part", "123", "G", "477"]
irb(main):002:0> parts[2]
=> "123"
irb(main):003:0> parts[4]
=> "477"

If you know the data is always separated by spaces and the number is
in the second and fourth places, this should work.
