What does the cumulative frequency show?
For any given value, a cumulative frequency table of chart shows the number of observations which are less than or equal to that value.
What are the benefits of cumulative frequency?

What represents the number of times all outcomes less than a given outcome occur?
It's cumulative frequency :)
How do you make a cumulative frequency table?
Given a frequency table,the first cumulative frequency is the same as the first frequency;the second cumulative frequency is the sum of the first cumulative frequency and the second [ordinary] frequency;the third cumulative frequency is the sum of the second cumulative frequency and the third [ordinary] frequency;and so on.An alternative definition is that the cumulative frequency for any value is the sum of all the frequencies less than or equal to that value.
