Find the value of $651.2 \div 4$.

Hint: Write the given value as fraction. So $651.2$ can be written as $\dfrac{{6512}}{{10}}$.

According to the question, we have to divide $651.2$ by $4$. Let its value come out as $x$. Then we have:
$ \Rightarrow x = 651.2 \div 4 = \dfrac{{651.2}}{4}$
We can write $651.2$ as $\dfrac{{6512}}{{10}}$. Doing this and simplifying further, we’ll get:
$
   \Rightarrow x = \dfrac{{651.2}}{4} = \dfrac{{6512}}{{10 \times 4}}, \\
   \Rightarrow x = \dfrac{{1628}}{{10}}, \\
   \Rightarrow x = 162.8 \\
$
Thus, the value of $651.2 \div 4$ is $162.8$.

Note: For removing decimals from a number, we divide it by a number having 1 with as many zeros as the number of decimal places we need to remove. For example:
$12.11 = \dfrac{{1211}}{{100}},0.367 = \dfrac{{367}}{{1000}},87.6 = \dfrac{{876}}{{10}}$
