In Real Life
In real life, division is widely used in computing the average price of products, and checking which item is a better buy.
Estimation in division is quite different from the others. Round off the divisor to a round number, like 79 to 80, and the dividend to a round multiple of the divisor, like 5578 to 5600. So, the quotient of 5578/79 is about 5600/80 which is 70.
The answer to a division problem is called the quotient.
