OK, let's crack this. We're given 828 and our task is to multiply it by 9. Essentially, we'll be adding 828 to itself 9 times.
Step 1: 0 + 828 = 828
Step 2: 828 + 828 = 1656
Step 3: 1656 + 828 = 2484
Step 4: 2484 + 828 = 3312
Step 5: 3312 + 828 = 4140
Step 6: 4140 + 828 = 4968
Step 7: 4968 + 828 = 5796
Step 8: 5796 + 828 = 6624
Step 9: 6624 + 828 = 7452

So, 828*9 = 7452
