If it is a repeating decimal for a rational number, such as 1/3 (.333...), you can write the sequence once and draw a "repeating" notation above the sequence. So in the case of 1/3, I would write ".3" with a horizontal line above the "3".
In the case of an irrational number such as Pi or a decimal for which you do not know the sequence repeated, you can just round it off to the precision required. For Pi, this is often expressed as "3.14," for example.

What do you call the kind of decimal that goes on forever and does not have digits which repeat?
Irrational.
What number goes on forever?
A recurring decimal (caused by the denominator of a fraction have a prime factor other than 2 and 5) or an irrational number (such as √2) goes on forever.
What is an example of a terminating decimal?
A terminating decimal is a decimal number whose digits don't go on forever, like 3.45. A non-terminating decimal is a decimal number that goes on forever, like 1/3 = 0.3333333... since the 3's go on forever. So any repeating decimal is non-terminating. Also, numbers like pi go on forever: 3.1415926535897932384626.......
