Sure! Here's a JavaScript function that takes in a value and a maximum value, and returns the division of the value by the maximum value:

```javascript
function divideByMax(value, maxValue) {
return value / maxValue;
}
```

You can use this function like this:

```javascript
console.log(divideByMax(10, 100)); // Output: 0.1
console.log(divideByMax(3, 5)); // Output: 0.6
console.log(divideByMax(6, 3)); // Output: 2
```

In the above examples, the first argument `value` represents the value you want to divide, and the second argument `maxValue` represents the maximum value for the division. The function then returns the result of the division.
