Express the following number in decimal notation. \[ 9.8 \times 10^{6} \] \[ 8.8 \times 10^{6}= \]

Step 1 ：First, simplify $9.8\times 10^{6}=98\times 10^{5}$.

Step 2 ：The factor of $10^{5}$ instructs us to move the decimal point in 98 five places to the right.

Step 3 ：The first step moves the decimal past the 8 and the next \(\boxed{4}\) steps each introduce a digit of 0.

Step 4 ：So, $9.8\times 10^{6}=9800000$.

Step 5 ：Similarly, simplify $8.8\times 10^{6}=88\times 10^{5}$.

Step 6 ：The factor of $10^{5}$ instructs us to move the decimal point in 88 five places to the right.

Step 7 ：The first step moves the decimal past the 8 and the next \(\boxed{4}\) steps each introduce a digit of 0.

Step 8 ：So, $8.8\times 10^{6}=8800000$.
