it is a bit different than in most other languages but try the other way round, 
selecting only the value of the variable depending on the condition 

<xsl:variable name="pages">
        <xsl:choose>
                <xsl:when test="leftover &gt; 0">
                        <xsl:value-of select="($totalitems - $leftover) div 
$pagesize + 1"/>
                </xsl:when>
                <xsl:otherwise>
                        <xsl:value-of select="($totalitems - $leftover) div 
$pagesize"/>
                </xsl:otherwise>
        </xsl:choose>
</xsl:variable>
