Razor Syntax for Division of 2 values

Hello:

Having trouble performing simple division on 2 values in Razor on a view:

Trying to divide a @Model.Sum with @Model.Count:

 @(@Model.Sum(i => i.MTDTotalSalesRollup)/@Model.Count())

I am getting a Attempted to divide by zero. I am able to get valid values for @Model.Sum(i => i.MTDTotalSalesRollup) and @Model.Count()

Any ideas? Thanks.
