Asking questions also requires some prerequisites. Not having successfully graduated from elementary school is not an option, sorry. —SA

Please don't be angry with me

No, I'm not angry at all, why? hope you won't be angry, too. You need to learn by yourself and rely on yourself more. Thank you for understanding. —SA

I'm a beginner and no one taught me how to use VB and I learn by my self with help of files on and the rest I found on the internet. so some of the thing that stack me up, I have to ask for help.

Divide the number by 100.

What's so hard about this?

Just parse the number in the textbox to a double and divide it by 100:
Dim value As String = textBox1.Text
Dim num As Double
If Double.TryParse(value, num) Then
    Dim percentage As Double = num / 100
    textBox2.Text = percentage.ToString()
    ' cannot parse the given string to a double
End If
