Daniel 2:33 "his feet part of iron and part of clay."
Daniel 2:41-43 "And whereas thou sawest the feet and toes, part of potters' clay, and part of iron, the kingdom shall be divided; but there shall be in it of the strength of the iron, forasmuch as thou sawest the iron mixed with miry clay. And as the toes of the feet were part of iron, and part of clay, so the kingdom shall be partly strong, and partly broken. And whereas thou sawest iron mixed with miry clay, they shall mingle themselves with the seed of men: but they shall not cleave one to another, even as iron is not mixed with clay."

Rome Divides into many kingdoms.

• Ostrogoths
• Heruli
• Vandals
• Visigoths (Spain)
• Franks (France)
• Suevi (Portugal)
• Burgundians (Switzerland)
• Anglo-Saxons (Britian)
• Lombards (Italy)
• Huns or Alemani (Germany)

Yea, you can argue who the ten are but the fact is that Rome did divide.
It also appears that Ten is a symbol for All or Complete such as the Ten Commandments.
