I'm not a professional biologist, I'm just trying to analyze some actual data. Where should I look up the location of a gene and nucleotides it consist of? How can I find it in DNA? Is there an algorithm that can be used?

Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.
To find the genomic location of a gene when you start with a gene name;
Use the UCSC Genome browser. This has a number of advantages. There are a number of species to choose from. It provides a representative image of the gene and regulatory elements that surround it. It can display a lot of extra information if you want to see it. The disadvantage ot the UCSC Genome browser is that the information density may overload non-professional users.
To find the genomic location of a gene when you start with a DNA sequence;
To search for a DNA nucleotide sequence using the link above, select Reference genomic sequences (refseq_genomic) from the pull-down tab in the Database field. Limiting the search to a species using the Organism field is also wise.
Both of these sites provide the information you are after. Taking time to read the help instructions will be useful.
