Roman Numeral Conversion Example

The largest Roman numeral that fits into 753 is Ⅾ for 500. 753 minus 500 is 253.
The largest Roman numeral that fits into 253 is Ⅽ for 100. 253 minus 100 is 153.
The largest Roman numeral that fits into 153 is Ⅽ for 100. 153 minus 100 is 53.
The largest Roman numeral that fits into 53 is Ⅼ for 50. 53 minus 50 is 3.
