If it is a real or rational number that is required of the quotient, I'm afraid any number in the set of real numbers are possible solutions for "blank". If, however, the quotient is only constrained to integers and/or whole and/or natural numbers, then the blank will be a multiple of 102. Let's name some to get you started.
102, 204, 306, 408, 510, 612, 714, 816, 918, 1020,1122, etc.

No. 102 can be divided (exactly) by neither 14 nor 12.
One possible answer: Blank 1 = 3150 Blank 2 = 10 Blank 3 = (2/315) = approx 0.006349
