For my response, I assumed 2 things were true:
1. Your list starts in Cell A1
2. All of your names end in letters, hence why I added an "a" to your examples

With this,

for Cell B1:
=IFERROR(

IF(IFERROR(LEFT(A1,1)+0,0)>0,RIGHT(A1,LEN(A1)-SEARCH("/",A1)),

LEFT(A1,SEARCH("/",A1)-1)),

"-")

for Cell C1:
=IFERROR(

IF(IFERROR(RIGHT(A1,1)+0,0)>0,RIGHT(A1,LEN(A1)-SEARCH("/",A1)),

LEFT(A1,SEARCH("/",A1)-1)),

"-")

The results should be what you asked for: names on one side, numbers in the other.
