using arrays to store and divide

i want to store the employees quarter sales and at the same time i want them to average with the companies quarter sales any ideas?

Code:

 Const intNUMBER_OF_EMPLOYEES As Integer = 10
    Const intMAX_EMPLOYEE As Integer = intNUMBER_OF_EMPLOYEES - 1


    ' class level variables
    Private Names(intMAX_EMPLOYEE) As String
    Private quarter1(9) As Single
    Private quarter2(9) As Single
    Private quarter3(9) As Single
    Private quarter4(9) As Single

    Private Sub txtQuarter1_Validating(ByVal sender As System.Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles txtQuarter1.Validating, txtQuarter4.Validating, txtQuarter3.Validating, txtQuarter2.Validating
        Dim input As String = CType(sender, TextBox).Text
        If IsNumeric(input) Then
            Dim number As Integer = CInt(input)
        Else
            MessageBox.Show("Please enter an integer.")
            e.Cancel = True
        End If

    End Sub

    

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

        Dim intCount As Integer

        For intCount = 0 To intMAX_EMPLOYEE
            Names(intCount) = TextBox1.Text
