I think that your expression seems to calculate correctly the wanted
value. For example:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
 <xsl:output omit-xml-declaration="yes" indent="yes"/>

 <xsl:variable name="total_articles" select="10"/>
 <xsl:variable name="articles_per_page" select="3"/>

 <xsl:template match="/">
  <xsl:value-of select=
  "floor(number($total_articles)-1)
  div
   $articles_per_page +1"/>
 </xsl:template>
</xsl:stylesheet>

When this transformation is applied on any XML document (not used at
all in this example), the wanted, correct result is produced:

4

Truly great madness cannot be achieved without significant intelligence.
---------------------------------------
To invent, you need a good imagination and a pile of junk
-------------------------------------
Never fight an inanimate object
-------------------------------------
To avoid situations in which you might make mistakes may be the
biggest mistake of all
------------------------------------
Quality means doing it right when no one is looking.
-------------------------------------
You've achieved success in your field when you don't know whether what
you're doing is work or play
-------------------------------------
Facts do not cease to exist because they are ignored.
-------------------------------------
I finally figured out the only reason to be alive is to enjoy it.
