I must assume you meant 251 / 4 (not 25 1/4).
251
-----
4
====
-3
-------
8
can be evaluated by inverting the second fraction and multiplying the result:
251 -8
----- * -----
8 3
The 8s cancel, leaving us with -251/3. Note that -248/3 = -83, so that the magnitue of -251/3 must be a little larger than -83.
251 divided by 3 is 83 with a remainder of 2: 251/3 = 83 2/3
So -251/3 = -83 2/3 (answer)
