formatted cell with leading zeros

I have a whole number in cell C2, but i am formatted it in Cell C3 to always have leading zeros combined with the number in Cell C2, where the result will be 8 digits long.

example, my number in cell C2 = 572 but i need it formatted to be 00000572, but if the number was 19 it needs to be formatted to be 00000019 and so on.

You can do it with custom formatting (format as 00000000), or enter the numbers (including leading zeros) starting with an apostrophe (e.g, '00000019), or format the cells as Text beforehand and enter the leading zeros.
