Sure thing, let's get straight to it. We start with 828 and we're going to multiply it by 26, which means adding 828 to itself 26 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
Step 10: 7452 + 828 = 8280
Step 11: 8280 + 828 = 9108
Step 12: 9108 + 828 = 9936
Step 13: 9936 + 828 = 10764
Step 14: 10764 + 828 = 11592
Step 15: 11592 + 828 = 12420
Step 16: 12420 + 828 = 13248
Step 17: 13248 + 828 = 14076
Step 18: 14076 + 828 = 14904
Step 19: 14904 + 828 = 15732
Step 20: 15732 + 828 = 16560
Step 21: 16560 + 828 = 17388
Step 22: 17388 + 828 = 18216
Step 23: 18216 + 828 = 19044
Step 24: 19044 + 828 = 19872
Step 25: 19872 + 828 = 20700
Step 26: 20700 + 828 = 21528

So, 828*26 = 21528
