How did God accomplish this?

God's plan was perfect. Because He knew what man would do He was able to plan accordingly.

Oftentimes we play "what if". "what if man does this, what will I do?" God did not play "what if". His foreknowledge is so great it is not a case if but when! By knowing perfectly what man is going to do, God does not have to manipulate nor micro manage people's lives to accomplish His purpose.
In this way man is still a "free moral agent" with the freedom and power to choose.

God then accomplished His will and His plan by knowing exactly what man would do and planning accordingly. No second guessing, no coercion, no mistakes.

So far we have been dealing with some very serious questions. I wish now to pose one that is serious yet somewhat lighter. This question requires a yes or no answer, and then a defense of that answer. Here goes. "Can God who is all powerful make a rock bigger than he can lift?"
