If you always expect a division here is one way:

irb(main):001:0> s = "$6,178.50 USD / 22,693.01 AED"
=> "$6,178.50 USD / 22,693.01 AED"

irb(main):011:0>
%r{\$(\d+(?:,\d+)*(?:\.\d+)?)\s*USD\s*/\s*(\d+(?:,\d+)*(?:\.\d+)?)\s*AED}
=~ s and p $1, $2
"6,178.50"
"22,693.01"
=> ["6,178.50", "22,693.01"]

Kind regards
