Dynamic creating radiobuttons and arange them inside form

I'm creating dynamically N radio buttons on form on this way:

 private void CreateRadioButton()
    {
        int rbCount = 40;

        System.Windows.Forms.RadioButton[] radioButtons = new System.Windows.Forms.RadioButton[rbCount];

        for (int i = 0; i < rbCount; ++i)
        {
            radioButtons[i] = new RadioButton();
            radioButtons[i].Text = Convert.ToString(i);
            int x = 514 + i*37;
            int y = 20;
            radioButtons[i].Location = new System.Drawing.Point(x,y);
            radioButtons[i].Size = new Size(37, 17);
            this.Controls.Add(radioButtons[i]);
        }
    }

In this case the radiobuttons are all created in one row but i need to arrange them in multiple rows inside specific region. Is it possible? What approach to use for this kind of problem?

If you want to fix your code without the suggested ways in the comments

private void CreateRadioButton()
{
    int rbCount = 40;
        int numberOfColumns = 8;
        var radioButtons = new RadioButton[rbCount];
        int y = 20;
        for (int i = 0; i < rbCount; ++i)
        {
            radioButtons[i] = new RadioButton();
            radioButtons[i].Text = Convert.ToString(i);
            if (i%numberOfColumns==0)  y += 20; 
            var x = 514 + i%numberOfColumns * 37;
            radioButtons[i].Location = new Point(x, y);
            radioButtons[i].Size = new Size(37, 17);
            this.Controls.Add(radioButtons[i]);
        }
}
