181 Divided by 2: A Step-by-Step Guide to Long Division

What's 181 divided by 2? This seemingly simple division problem offers a great opportunity to refresh our understanding of long division, a fundamental arithmetic skill. Let's break it down step-by-step.

Understanding the Problem: 181 ÷ 2

The problem "181 divided by 2" asks how many times the number 2 fits into 181. We can't do this perfectly, as 181 is an odd number and therefore not evenly divisible by 2. This means we'll have a remainder.

Step-by-Step Long Division

Here's how to solve 181 ÷ 2 using long division:

1. Set up the problem: Write the dividend (181) inside the long division symbol and the divisor (2) outside.

   2 | 181
   

2. Divide the hundreds: How many times does 2 go into 1? It doesn't, so we move to the tens place. How many times does 2 go into 18? It goes in 9 times (9 x 2 = 18). Write the 9 above the 8 in 181.

      9
   2 | 181
   

3. Multiply and subtract: Multiply the quotient (9) by the divisor (2): 9 x 2 = 18. Subtract this result from the first two digits of the dividend (18): 18 - 18 = 0.

      9
   2 | 181
     -18
       0
   

4. Bring down the ones: Bring down the next digit (1) from the dividend.

      9
   2 | 181
     -18
       01
   

5. Divide the ones: How many times does 2 go into 1? It goes in 0 times. Write 0 above the 1.

      90
   2 | 181
     -18
       01
   

6. Multiply and subtract: Multiply the new quotient digit (0) by the divisor (2): 0 x 2 = 0. Subtract this from the remaining digit (1): 1 - 0 = 1.

      90
   2 | 181
     -18
       01
       -0
        1
   

7. Remainder: The number 1 is the remainder. This means 2 goes into 181 ninety times with one left over.

The Answer

Therefore, 181 divided by 2 is $\boxed{90 R 1}$ (90 with a remainder of 1). This can also be expressed as a decimal: 90.5. To get the decimal, you divide the remainder (1) by the divisor (2): 1 ÷ 2 = 0.5.

Practical Applications

Understanding long division is crucial for various everyday tasks, including:

• Sharing equally: Dividing resources among people.
• Calculating unit prices: Finding the cost per item.
• Baking and cooking: Following recipes that require precise measurements.
• Financial planning: Budgeting and managing finances.

Mastering long division, even with seemingly simple problems like 181 divided by 2, builds a solid foundation for more complex mathematical operations.
