(At this point the numbers behind the comma and specifically behind the first "1" are repeated endlessly. There was a specific term for this but I don't know it, because english is not my primary language. But basically: 2424,1153846153846153846....And to avoid writing endlessly repeating numbers you put a line at the top. You get the point)
