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>
