OK, let's crack this. We're given 705 and our task is to multiply it by 11. Essentially, we'll be adding 705 to itself 11 times.
Step 1: 0 + 705 = 705
Step 2: 705 + 705 = 1410
Step 3: 1410 + 705 = 2115
Step 4: 2115 + 705 = 2820
Step 5: 2820 + 705 = 3525
Step 6: 3525 + 705 = 4230
Step 7: 4230 + 705 = 4935
Step 8: 4935 + 705 = 5640
Step 9: 5640 + 705 = 6345
Step 10: 6345 + 705 = 7050
Step 11: 7050 + 705 = 7755

So, 705*11 = 7755
