Step 1: Since 90207588 do not have a decimal point, we will add one at the end of the number 90207588.
90207588.
Step 2: 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).
9.0207588.
Step 3: We moved the decimal point 7 spaces to the right. Therefore, the exponent on base 10 will be positive 7.Now we know that the:
Mantissa = 9.0207588
Exponent = 7
So, the solution is:
$$90207588 = \color{blue}{ 9.0207588} \cdot 10^{ \color{red}{ 7 }}$$
