I made a mistake of dividing 172 by a certain number when I had to divide by 4, and the resulting quotient was 28 less than the correctly calculated quotient, and the remainder was 7. Find this certain number.
172 7 [OP_SUB] 172 4 [OP_DIV] 28 [OP_SUB] [OP_DIV]
var_a = 172
var_b = 7
var_c = var_a - var_b
var_d = 172
var_e = 4
var_f = var_d / var_e
var_g = 28
var_h = var_f - var_g
var_i = var_c / var_h
print(int(var_i))
