So, you want to know how to solve 78 divided by 30? This seemingly simple division problem offers a great opportunity to explore the principles of long division. Let's break it down step-by-step.

Understanding the Problem: 78 ÷ 30

The problem 78 divided by 30 (written as 78 ÷ 30 or 78/30) asks: "How many times does 30 fit into 78?" We'll use long division to find the answer, which will include both a whole number and a remainder (or a decimal if we choose to take the calculation further).

Step-by-Step Long Division: 78 ÷ 30

Here's how to perform the long division:

1. Set up the problem: Write the dividend (78) inside the long division symbol and the divisor (30) outside.

   30 | 78
   

2. Divide: How many times does 30 go into 78? It goes in 2 times (30 x 2 = 60). Write the "2" above the 8 in 78.

      2
   30 | 78
   

3. Multiply: Multiply the quotient (2) by the divisor (30): 2 x 30 = 60. Write this underneath the 78.

      2
   30 | 78
      60
   

4. Subtract: Subtract 60 from 78: 78 - 60 = 18. This is the remainder.

      2
   30 | 78
      60
      --
      18
   

Interpreting the Result: Quotient and Remainder

Our long division shows that 30 goes into 78 two times with a remainder of 18. We can express this as:

• 2 with a remainder of 18: This is the most common way to express the answer in the context of simple division.

• 2.6: If we want to express this as a decimal, we can continue the long division process. We'd add a decimal point and a zero to the remainder, bringing it down as 180. Then we divide 180 by 30, which gives us 6. This makes our final answer 2.6

Alternative Methods

While long division is a standard method, we could also consider estimating. Knowing that 30 x 3 = 90 which is more than 78, we can quickly infer that the answer will be close to 2.

Conclusion: Mastering Division

Understanding how to divide numbers like 78 by 30 is fundamental to math. Mastering long division, along with learning how to interpret remainders and decimals, is a crucial skill for various mathematical problems. Remember to practice regularly to build your proficiency.
