THIS WENT COMPLETELY OVER MY HEADCan u please point me in the right direction

There is an interesting method from India for calculating the decimal form of a fractin. These are the three steps for dealing with it:

1) Write the units digit of the numerator towards the right side of the page and carry the other digits of the numerator

2) Multiply the units digit just written by more than the number before (in the denominator and add the carried number. Write the units digit of the result on the left of the previous units digit and carry the other digits of the result

3) Continue until the sequence of units digit repeats. The sequence up to this point is the repetend for the fraction

A. Use this mehod to find the decimal form of:

16/39, 23/39, 46/79, 14/79, 4/21, 10/21, 13/53, 27/53

B. Explain how we can use this method for the fractions 7/26 and 36/205 and find their decimal form
