[I hope you can cope with English]

Use a Canvas widget:

import tkinter as tk

root = tk.Tk()
canvas = tk.Canvas(root, width=240, height=240)
canvas.pack()

canvas.create_oval((20, 20), (220, 220), width=10, fill="white")
tag = canvas.create_text(120, 120, text="42", justify=tk.CENTER, 
font=("Helvetica", 110), fill="#800")

if 1: # fancy stuff; you can safely remove the complete if-statement

    def n(x):
        while True:
            for i in reversed(range(x+1)):
                yield i

    values = n(42)
    def down():
        text = str(next(values))
        canvas.itemconfig(tag, text=text)
        root.after(300, down)

    down()

root.mainloop()
