Evaluate:
`0.00015 div 0.25`

Answer

To evaluate the expression \( 0.00015 \div 0.25 \), we can follow these steps:

### Step 1: Rewrite the division
We start with the expression:
\[ 0.00015 \div 0.25 \]
This can be rewritten as a fraction:
\[ \frac{0.00015}{0.25} \]

### Step 2: Eliminate the decimal in the denominator
To eliminate the decimal in the denominator, we can multiply both the numerator and the denominator by 100 (since 0.25 has two decimal places):
\[ \frac{0.00015 \times 100}{0.25 \times 100} = \frac{0.015}{25} \]

### Step 3: Convert the numerator to a whole number
Next, we can convert \( 0.015 \) to a whole number by multiplying both the numerator and the denominator by 1000 (since \( 0.015 \) has three decimal places):
\[ \frac{0.015 \times 1000}{25 \times 1000} = \frac{15}{25000} \]

### Step 4: Simplify the fraction
Now, we simplify the fraction \( \frac{15}{25000} \). We can divide both the numerator and the denominator by 5:
\[ \frac{15 \div 5}{25000 \div 5} = \frac{3}{5000} \]

### Step 5: Convert the simplified fraction to decimal
To convert \( \frac{3}{5000} \) to a decimal, we perform the division:
\[ 3 \div 5000 = 0.0006 \]

### Final Answer
Thus, the value of \( 0.00015 \div 0.25 \) is:
\[ \boxed{0.0006} \]
