Are you talking about cases when your sentence doesn't fit a line and you want to separate the last word and move part of it to the next line? Yes, you can do it in Russian and you must use a hyphen between the two parts of a word. There are some rules to it. For example:
You can't leave or move to the next line just 1 letter.
You can't separate the letters й, ы,ъ, ь from the preceding letter. (Правильно: тай -на, разы-грать, маль-чик. Неправильно: та-йна, раз-ыграть, мал -ьчик).
You can't leave part of a prefix on one line and move the last consonant to the next one. (Правильно: пред-почитать. Неправильно: пре-дпочитать).
