Answer:
4890
Explanation:
Recognize the denominator has been multiplied by 100:
0.03 × 100 = 3
To have the same division problem, the numerator must also be multiplied by 100. This is the sort of decimal point adjustment usually carried out for long division: the divisor is made to be an integer, and the decimal point of the dividend is moved the same direction by the same number of places.

The missing number is 4890.
____
The quotient is 1630.
