[mrtg] How to do a bit more arithmetic with returned OID values

Although a recent newcomer to configuring MRTG, I have read all the 
manuals and Email archives, but can't find an answer to my problem. 
Can anyone help please ?

I want to graph two values, one of which is a %, and thus maximum 
value is 100, whilst the other is a value up to 1000. Therefore I 
want to scale just one of these values by dividing by 10.

It appears that a line like the following can divide one pair of 
OID values by another.

Target[BUTECF1R.1]: at BUTECF1R: / at BUTECF1R:

What I can't find out is how to divide one of the pair of values by a 
fixed number such as 10.

Any ideas (other than attempting to find an OID value that is always 
10) ?
