How can you tell when its a repeating decimal?!

how can you tell when the digits begin repeating?!

1,360/220

Wouldn't that be

6 remainder 150?

1,360/220means 1360:220that equals. = 6.1818181818 ... and that goes to infinity it will never be a whole number it will repeat ... repeat repeat. the sequence will repeat itself you will need to work the problem out because some number are quite long before they repeat themselves and you won't think they are and there can be many numbers that repeat
