You made a mistake and  multiplied a certain number by 10 when you should have multiplied it by 1/100, and got 2804. How much is it when you calculate correctly?
2804 10 [OP_DIV] 1/100 [OP_MUL]
var_a = 2804
var_b = 10
var_c = var_a / var_b
var_d = 0.01
var_e = var_c * var_d
print('{:.2f}'.format(round(var_e+1e-10,2)))
