Step 1: Move the decimal point from its current position (the black dot) to a position immediately to the right of the first nonzero digit (the red dot).

2.20588235.29412

Step 2: We moved the decimal point 8 spaces to the right. Therefore, the exponent on base 10 will be positive 8.Now we know that the:

Mantissa = 2.2058823529412

Exponent = 8

So, the solution is:
