The square root can be found, by 


0.30  lies between 25 and 36, gives 0.5

You then 054 .2916 and .55 .3025, gives 0.54

Then we look for 125-16 gives 109 => divide by 1.1, so 84 / 1.1 = .76


So the mental calculation gives se 0.5476.


By hand, you use a method of change of divisor.  Note (a+b)=a²+2ab+b².  We see that a² is already subtracted, and the subtract is (2a+b)*b, 2a is twice the dividend, and you append b to the end of the number.
