1056/23.
=23/1056/46
92
-----------
136
138
-------------
When we multiply 23*5=115.
2
But I take one 1 more bigger digit I multiply 23*6=138
Difference of this two numbers is 2.
This is the simplest way.

1056+2=1058, it is completely divided by 23, so difference no. 1056-1058 =2, because 1058/23 =46.

The best way lets assume 1056 to be 1+0+5+6=12=1+2=3 --> 1.
23=2+3=5 --> 2.
Hence 2 must be added to (1) to get completely divisible by 23.
23=2+3=5 --> 2.
Hence 2 must be added to (1) to get completely divisible by 23.

But the reminder is not 2 how it comes 2?

@Nandi.
Please apply same formula in 1045 instead of 1056, 23 will remain same.

Why we did 23-21?

Simple,
They are asking only which is a least number make 1056 becomes divisible by 23.
So, we know divisibility means the remainder will be zero.
First, divide the1056 by 23.
And; we know 23*6=138, hence the given number 105(6) is must be 105(8) then we divided). Hence add 2 finally we get remainder zero.

When 1056 divided by 23 it yields 21 but we need to get "0" as remainder if we add +2 to 21 (i.e. 1058 it gives 23 as the remainder when it gets divided by 23) and it 23 get divided by 23 yields zero "0".

Basically we have to %(mod) operation here;
1056%23=
1056/23=45.91=46.
46*23=1058.
1058-1056=2 => answer.
1056%23=
1056/23=45.91=46.
46*23=1058.
1058-1056=2 => answer.
