• First decimal place: Determine how many times 16 fits into 90. 16 multiplied by 5 equals 80. This is the highest multiple of 16 that does not exceed 90. Write 5 as the first digit after the decimal point in the quotient.
• Calculate remainder: Subtract 80 from 90, leaving a remainder of 10.
• Second decimal place: Append another zero to the remainder, making it 100.
• Determine next digit: Find how many times 16 fits into 100. 16 multiplied by 6 equals 96. Write 6 in the quotient.
• Calculate remainder: Subtract 96 from 100, leaving a remainder of 4.
• Third decimal place: Add a zero to the remainder, creating 40.
• Determine next digit: Calculate how many times 16 fits into 40. 16 multiplied by 2 equals 32. Write 2 in the quotient.
• Calculate remainder: Subtract 32 from 40, leaving a remainder of 8.
• Fourth decimal place: Append a final zero to the remainder, resulting in 80.
• Final digit: Determine how many times 16 fits into 80. 16 multiplied by 5 equals 80. Write 5 in the quotient.
• Completion: With a remainder of 0, the division is complete.

Therefore, the decimal equivalent of the fraction 9/16 is precisely 0.5625.
