h) Now consider 64 and 641. Look at the first digit of the dividend and the
divisor. Here also you get small numbers. Ask : how many 6’s in 6. By saying
1, set the 1 to the right of the square root and to the right of number 64.
Multiply 1 with 641 and subtract that from the 61. No number is available in
the abacus as remainder.
i) You will get the answer as 321.
