Evaluate:
`3.216 div 0.16

Answer

To evaluate \( 3.216 \div 0.16 \), we can follow these steps:

### Step 1: Convert the division into a fraction
We can express the division as a fraction:
\[ \frac{3.216}{0.16} \]

### Step 2: Eliminate the decimals
To eliminate the decimals, we can multiply both the numerator and the denominator by 100 (since there are two decimal places in 0.16):
\[ \frac{3.216 \times 100}{0.16 \times 100} = \frac{321.6}{16} \]

### Step 3: Simplify the fraction
Now we need to divide 321.6 by 16. To make it easier, we can convert 321.6 into an integer by multiplying by 10:
\[ \frac{3216}{160} \]

### Step 4: Perform the division
Now we can divide 3216 by 16:
- 16 goes into 32 two times (2 × 16 = 32), leaving a remainder of 0.
- Bring down the next digit (1), making it 1. Since 16 cannot go into 1, we put a 0 in the quotient.
- Bring down the next digit (6), making it 16. 16 goes into 16 one time (1 × 16 = 16), leaving a remainder of 0.

So, \( 3216 \div 16 = 201 \).

### Step 5: Adjust for the decimal
Since we multiplied the denominator by 10, we need to adjust our answer by dividing by 10:
\[ \frac{201}{10} = 20.1 \]

### Final Answer
Thus, the final answer is:
\[ \boxed{20.1} \]
