Step 13: 2568 + 214 = 2782
Step 14: 2782 + 214 = 2996
Step 15: 2996 + 214 = 3210
Step 16: 3210 + 214 = 3424
Step 17: 3424 + 214 = 3638
Step 18: 3638 + 214 = 3852
Step 19: 3852 + 214 = 4066
Step 20: 4066 + 214 = 4280
Step 21: 4280 + 214 = 4494
Step 22: 4494 + 214 = 4708
Step 23: 4708 + 214 = 4922
Step 24: 4922 + 214 = 5136
Step 25: 5136 + 214 = 5350
Step 26: 5350 + 214 = 5564
Step 27: 5564 + 214 = 5778
Step 28: 5778 + 214 = 5992
Step 29: 5992 + 214 = 6206
Step 30: 6206 + 214 = 6420
Step 31: 6420 + 214 = 6634
Step 32: 6634 + 214 = 6848
Step 33: 6848 + 214 = 7062
Step 34: 7062 + 214 = 7276
Step 35: 7276 + 214 = 7490
Step 36: 7490 + 214 = 7704
Step 37: 7704 + 214 = 7918
Step 38: 7918 + 214 = 8132
Step 39: 8132 + 214 = 8346
Step 40: 8346 + 214 = 8560
Step 41: 8560 + 214 = 8774
Step 42: 8774 + 214 = 8988
Step 43: 8988 + 214 = 9202
Step 44: 9202 + 214 = 9416
Step 45: 9416 + 214 = 9630
Step 46: 9630 + 214 = 9844
Step 47: 9844 + 214 = 10058
Step 48: 10058 + 214 = 10272
Step 49: 10272 + 214 = 10486
Step 50: 10486 + 214 = 10700
Step 51: 10700 + 214 = 10914

So, 214*51 = 10914
