Expanded form is a way to write a number such that all of the place value components of the number are separated.
When we write a number in expanded form, each digit is broken out and multiplied by its place value, such that the sum of all of the values equals the original number.
So when writing 65,040,000,010 in its expanded form, it looks like this:
60000000000
+5000000000
+0
+40000000
+0
+0
