To divide, we move the decimal point of the divisor (the number we are dividing by) to the right until it becomes a whole number. Then, we move the decimal point of the dividend (the number we are dividing) the same number of times to the right. We can then perform the division as usual.

In this case, we have:

```
   472
  ━━━━
17.202
```

We move the decimal point of 17.202 to the right two places to get 1720.2. We must then move the decimal point of 472 two places to the right as well to get:

```
      4.72
  ━━━━━━━
1 7 2 0 . 2
```

We can now perform the division as usual to get:

```
      4.72
  ━━━━━━━
1 7 2 0 . 2
     1 4 1 6
     ───────
       3 0 6
       2 1 7
       ─────
         893
         708
         ───
         1850
         1720
         ───
          130
```

So the answer is 3.66 (choice C).
