As a shell script (i.e. just paste in body of command):

    echo "Aprox. page #$(( (TM_LINE_NUMBER+37) / 38 ))"
    echo "Aprox. total pages $(( `wc -l` / 38 + 1 ))"

Basically $((…)) allows you to do math in the shell. `…` runs a  
command, in this case, it runs `wc -l` which is word count (but with - 
l, gives number of lines).

The command should have Input set to Entire Document.

I add 37 to the current line number, since the shell truncates the  
value, and I assume you want it rounded up. I.e. line 1-37 should say  
page #1.

As for total number of pages, I just add 1 to the result, since `wc`  
gives a zero-based number, so I would have to add one to make it one- 
based, and then 37 to round up (1 + 37 = 38).
