Divide :
`18.6 div 10`

Answer

To solve the problem of dividing 18.6 by 10, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Division**: We need to divide the decimal number 18.6 by 10. This can be written as:
\[ 18.6 \div 10 \]

2. **Identify the Movement of the Decimal Point**: When dividing by 10 (or any power of 10), the decimal point in the number moves to the left. The number of places the decimal point moves is equal to the number of zeros in the divisor (in this case, 10 has one zero).

3. **Move the Decimal Point**: Since we are dividing by 10 (which has one zero), we move the decimal point in 18.6 one place to the left.
- The original number is 18.6.
- Moving the decimal point one place to the left gives us:
\[ 1.86 \]

4. **Write the Final Answer**: Therefore, the result of dividing 18.6 by 10 is:
\[ 1.86 \]

### Final Answer:
\[ 18.6 \div 10 = 1.86 \]
