You can check by using your estimated number and comparing it with your exact quotient.
An exact value is a precise number or quantity without any uncertainty, often represented by whole numbers, fractions, or irrational numbers in their true forms. In contrast, an approximation is an estimated value that is close to the exact value but may lack precision, often due to rounding or simplification for ease of calculation or understanding. Exact values provide definitive answers, while approximations are useful in practical situations where perfect accuracy is not necessary.
