If you have Excel 2016+ with the TEXTJOIN function, you can use this array formula:

=TEXTJOIN("/",TRUE,FILTERXML("" & SUBSTITUTE(A1,"/","")& "","//s[position()

Since this is an array formula, you need to "confirm" it by holding down ctrl + shift while hitting enter. If you do this correctly, Excel will place braces {...} around the formula as observed in the formula bar
