= ((1/8) ÷ (1/8)) ÷( (1/8) ÷ (1/8))  = (1) ÷( 1)  = 1

$$=\:\left(\frac{\mathrm{1}}{\mathrm{8}}\:\boldsymbol{\div}\:\frac{\mathrm{1}}{\mathrm{8}}\right)\:\boldsymbol{\div}\left(\:\frac{\mathrm{1}}{\mathrm{8}}\:\boldsymbol{\div}\:\frac{\mathrm{1}}{\mathrm{8}}\right) \\ $$$$=\:\left(\mathrm{1}\right)\:\boldsymbol{\div}\left(\:\mathrm{1}\right) \\ $$$$=\:\mathrm{1} \\ $$

Wrong for you sir, not for me.  It′s a question of notation.  In my country ÷ is not the same as /  The question is not clear for me. :−)

(1/8)÷(1/8)÷(1/8)÷(1/8)  = (1/8)×8×8×8   = 8×8  = 64

$$\frac{\mathrm{1}}{\mathrm{8}}\boldsymbol{\div}\frac{\mathrm{1}}{\mathrm{8}}\boldsymbol{\div}\frac{\mathrm{1}}{\mathrm{8}}\boldsymbol{\div}\frac{\mathrm{1}}{\mathrm{8}} \\ $$$$=\:\frac{\mathrm{1}}{\mathrm{8}}×\mathrm{8}×\mathrm{8}×\mathrm{8}\: \\ $$$$=\:\mathrm{8}×\mathrm{8} \\ $$$$=\:\mathrm{64}\: \\ $$
