First you can count multiples of 7 all the way up to 84. 7,14,21,28,35,42,49,56,63,70,77,and 84. 
Or you can do 7 x 12 equals 84. 
Second write down the long division way 84/7. 
7 goes into 8 one time write 7 at the top then write one at the bottom bring down the 4 and make it 14 
you know 7 x 2 = 14 so 12 x 7 equals 14.
