Step 1: 0 + 393 = 393
Step 2: 393 + 393 = 786
Step 3: 786 + 393 = 1179
Step 4: 1179 + 393 = 1572
Step 5: 1572 + 393 = 1965
Step 6: 1965 + 393 = 2358
Step 7: 2358 + 393 = 2751
Step 8: 2751 + 393 = 3144
Step 9: 3144 + 393 = 3537
Step 10: 3537 + 393 = 3930
Step 11: 3930 + 393 = 4323
Step 12: 4323 + 393 = 4716
Step 13: 4716 + 393 = 5109
Step 14: 5109 + 393 = 5502
Step 15: 5502 + 393 = 5895
Step 16: 5895 + 393 = 6288
Step 17: 6288 + 393 = 6681
Step 18: 6681 + 393 = 7074
Step 19: 7074 + 393 = 7467
Step 20: 7467 + 393 = 7860
Step 21: 7860 + 393 = 8253
Step 22: 8253 + 393 = 8646
Step 23: 8646 + 393 = 9039
Step 24: 9039 + 393 = 9432
Step 25: 9432 + 393 = 9825
Step 26: 9825 + 393 = 10218
Step 27: 10218 + 393 = 10611
Step 28: 10611 + 393 = 11004
Step 29: 11004 + 393 = 11397
Step 30: 11397 + 393 = 11790
Step 31: 11790 + 393 = 12183
Step 32: 12183 + 393 = 12576
Step 33: 12576 + 393 = 12969
Step 34: 12969 + 393 = 13362
Step 35: 13362 + 393 = 13755

So, 393*35 = 13755
