What programming languages support arbitrary precision arithmetic and could you give a short example of how to print an arbitrary number of digits?

Some programming languages such as Lisp, Python, Perl, Haskell and Ruby use, or have an option to use, arbitrary-precision numbers for all integer arithmetic. Although this reduces performance, it eliminates the possibility of incorrect results (or exceptions) due to simple overflow.
Arbitrary-Precision arithmetic, also known as "bignum" or simply "long arithmetic" is a set of data structures and algorithms which allows to process much greater numbers than can be fit in standard data types.
Python does have arbitrary precision integers. The number your code creates is not an integer. a mere python3 -c "print(999999999999999999999999 / 3)" would show you the issue immediately (it prints a float instead of integer).
vpa( x ) uses variable-precision floating-point arithmetic (VPA) to evaluate each element of the symbolic input x to at least d significant digits, where d is the value of the digits function. The default value of digits is 32. example. vpa( x , d ) uses at least d significant digits, instead of the value of digits .
Some languages have this support built in. For example, take a look at java.math.BigDecimal in Java, or decimal.Decimal in Python.
Other languages frequently have a library available to provide this feature. For example, in C you could use GMP or other options.
The "Arbitrary-precision software" section of this article gives a good rundown of your options.
