Spacing recordset results

I am wondering if this is possible, I have 7 columns of data & one of them is called "cardnumber" & what I am trying to find out is if there is a way to space out records based on cardnumber grouping, for example I would like to see group of records for all "4" cardnumbers, then a free space or horizontal bar & then all records for all "5" cardnumbers etc.
This way it will be a little easier to read the data.

Thank you
