What is the format to get the 5 decimal places but without rounding off?

Here's the sample:

textbox1 / textbox2 = textbox3

Textbox1 = 3768.62
Textbox2 = 134
Textbox3 should be only 28.12402

I have this below formula but this still it's rounding.


Private Sub TextBox1_Change()

If IsNumeric(TextBox1) And IsNumeric(TextBox2) Then
       TextBox3.Value = Format(TextBox1 / TextBox2, "####.00000")
      
      
   Else
   
   TextBox3.Value = ""

    End If


End Sub

Private Sub TextBox2_Change()


If IsNumeric(TextBox1) And IsNumeric(TextBox2) Then
       TextBox3.Value = Format(TextBox1 / TextBox2, "####.00000")
    
       
      
   Else
   TextBox3.Value = ""
   
    End If


End Sub
