Sure thing! We've got 707 and we're gonna multiply it by 9. That's the same as adding 707 to itself 9 times.
Step 1: 0 + 707 = 707
Step 2: 707 + 707 = 1414
Step 3: 1414 + 707 = 2121
Step 4: 2121 + 707 = 2828
Step 5: 2828 + 707 = 3535
Step 6: 3535 + 707 = 4242
Step 7: 4242 + 707 = 4949
Step 8: 4949 + 707 = 5656
Step 9: 5656 + 707 = 6363

So, 707*9 = 6363
