Step 4: Double the quotient (2 × 4 = 8) and write it as 8 in the box on its right. Since 64 is the decimal part so, put a decimal point in the quotient (i.e. 4)

Step 5: Guess the digit to fill the box in such a way that the product of the new divisor and the digit is equal to or less than the new dividend 164. In this case the digit is 2. Divide and get the remainder.

Step 6: Since the remainder is zero and no pairs left. 17.64= 4.2 Now, let us see some more examples.
