##qucik_note_sharing## copied _divisiblity by 7
10/7 --> not divisible but remainder is not 0 or 1 or -1
100/7 --> not divisible but remainder is not 0 or 1 or -1
1000/7 --> not divisible but remainder is -1
so every three digit we will have -1 remainder ..
if 10^3 has -1 remainder , 10^6 has 1 as remainder...
so its alternative
say number is 123130 to checked divisibility by 7 .,..
so according to this concept we have , 130 - 123= 7 which is divisible by 7
