If you divide a piece of wire into 8 equal parts and then divide it into 8 equal parts, find how many centimeters (cm) it is. However, the length of the wire is 69.76 centimeters (cm).
69.76 8 [OP_DIV] 8 [OP_DIV]
var_a = 69.76
var_b = 8
var_c = var_a / var_b
var_d = 8
var_e = var_c / var_d
print('{:.2f}'.format(round(var_e+1e-10,2)))
