How do I divide each value in this row by a value in one of the columns?

How would I divide each value in this row by the count(CMDB SERVER) calc?

Assuming the columns are dynamic you'll want to use foreach:

... | rename "count(CMDB SERVER)" as cmdb | foreach count* [eval <<FIELD>> = '<<FIELD>>' / cmdb] | rename cmdb as "count(CMDB SERVER)"

You can use the eval command to create a new columns or modify the values of the current columns (documentation here: http://docs.splunk.com/Documentation/Splunk/6.2.0/SearchReference/eval)

Renaming your columns will make the eval strings a bit neater, for example..

... | rename "count(CMDB Server" as "CMDB_Server", "count(CMDB APP)" as "CMDB_App" | eval CMDB_App = CMDB_App/CMDB_Server
