Sure thing, let's get straight to it. We start with 261 and we're going to multiply it by 19, which means adding 261 to itself 19 times.
Step 1: 0 + 261 = 261
Step 2: 261 + 261 = 522
Step 3: 522 + 261 = 783
Step 4: 783 + 261 = 1044
Step 5: 1044 + 261 = 1305
Step 6: 1305 + 261 = 1566
Step 7: 1566 + 261 = 1827
Step 8: 1827 + 261 = 2088
Step 9: 2088 + 261 = 2349
Step 10: 2349 + 261 = 2610
Step 11: 2610 + 261 = 2871
Step 12: 2871 + 261 = 3132
Step 13: 3132 + 261 = 3393
Step 14: 3393 + 261 = 3654
Step 15: 3654 + 261 = 3915
Step 16: 3915 + 261 = 4176
Step 17: 4176 + 261 = 4437
Step 18: 4437 + 261 = 4698
Step 19: 4698 + 261 = 4959

So, 261*19 = 4959
