Display division value in Label using C# in ASP.Net

hi

in message.aspx page is 2 label:

<asp:Label ID="Lblresult" runat="server" CssClass="MeR"> </asp:Label>
<asp:Label ID="Lblcredit" runat="server" CssClass="MeR1">129000</asp:Label>

I want do it:

Lblresult.text=Lblcredit.text / 12.9

I mean I want Lblcredit.text devide by 12.9 and show result into Lblresult

129000 /12.9= 10000

How I can do it?

Best regards
