# --description--

我们可以在 JavaScript 中做除法运算。

JavaScript 中使用`/`符号做除法运算。

**示例**

```js
myVar = 16 / 2; // assigned 8
```

# --instructions--

改变数值`0`来让变量`quotient`的值等于`2`。

# --hints--

要使`quotient`的值等于 2。

```js
assert(quotient === 2);
```

使用`/`运算符。

```js
assert(/\d+\s*\/\s*\d+/.test(code));
```

# --seed--

## --after-user-code--

```js
(function(z){return 'quotient = '+z;})(quotient);
```

## --seed-contents--

```js
var quotient = 66 / 0;
```

# --solutions--

```js
var quotient = 66 / 33;
```
