Thank you for the question, Josh.
The preferred method for transcribing a number with a bar over it is to use the symbol for "bar over previous item" given in Guidelines for Technical Material section 12 and to use braille grouping indicators where necessary to designate the "item" to which that bar over applies.
I would transcribe the print you shared ["one-point-nine, division sign, two-point-four, equals, zero-point-seven-nine-one-six with a bar over the six"] as shown below:
#a4i"/#b4d "7 #j4gia<#f>:
More information and explanation of transcribing this kind of recurring decimal notation is included in our short webinar "Decimals, Including Repeating Decimals," which is in the archive of UEB Technical Material webinars.
