We round both numbers to the nearest whole number: \[ \begin{array}{ccccl} 16.4 & \div & 3.6 \\ \big\downarrow && \big\downarrow \\ \color{blue}16 & \div & \color{blue}4 \end{array} \] Hence, we need to find the value of $16 \div 4.$ Computing the quotient, we get:

\[ 16 \div 4 = 4 \]

Therefore, $16.4 \div 3.6$ is approximately equal to $4.$

First, we round the dividend to the nearest whole number: \[ 96.2 \rightarrow 96 \]

Hence, we need to find the value of $96 \div 4.$ Computing the quotient, we get:

Hence, \[ 96 \div 4 = 24 \]

Therefore, $96.2 \div 4$ is approximately equal to $24.$

First, we round the divisor to the nearest ten: \[ 11.1 \rightarrow 10 \]

Now, notice that there is $1$ zero in $10.$ Hence, we move the decimal point one place to the left.

\[ 4.3 \rightarrow 0.43 \]

Therefore, $4.3 \div 11.1$ is approximately equal to $0.43.$

First, we round the divisor to the nearest hundred: \[ 97.7 \rightarrow 100 \]

Now, we need to compute \[ 6.4 \div 100. \]

There are $2$ zeros in $100,$ so we move the decimal point two places to the left: \[ 6.4 \rightarrow 0.064 \]

Therefore, $6.4 \div 97.7$ is approximately equal to $0.064\,.$

First, we round the divisor to the nearest thousand: \[ 990 \rightarrow 1000 \]

Now, we need to compute \[ 1455 \div 1000. \]

Now, notice that there are $3$ zeros in $1000.$ Hence, we move the decimal point three places to the left.

\[ 1455 \rightarrow 1.455 \]

Therefore, $1455 \div 990$ is approximately equal to $1.455.$

First, we round the divisor to the nearest whole number: \[ 4.15 \rightarrow 4 \]

Hence, we need to find the value of $124 \div 4.$ Computing the quotient, we get the following.

Therefore, \[ 124 \div 4 = 31. \]

Therefore, $124 \div 4.15$ is approximately equal to $31.$

We round both numbers to the nearest whole number: \[ \begin{array}{ccccl} 374.5 & \div & 5.05 \\ \big\downarrow && \big\downarrow \\ \color{blue}375& \div & \color{blue}5 \end{array} \]

Now, we need to find the value of \[ 375 \div 5. \]

So, we go through the long division procedure as usual:

Therefore, \[ 375 \div 5 = 75. \]

Therefore, $374.5 \div 5.05$ is approximately equal to $75.$

We round both numbers to the nearest whole number: \[ \begin{array}{ccccl} 262.5 & \div & 3.09 \\ \big\downarrow && \big\downarrow \\ \color{blue}263 & \div & \color{blue}3 \end{array} \]

Now, we need to find the value of \[ 263 \div 3. \]

So, we go through the long division procedure as usual:

Therefore, \[ 263 \div 3 = 87\,\text{R} 2. \]

The remainder $2$ is closer to the divisor $3$ than to $0.$ So, to round to the nearest whole number, we must round up:

\[ 263 \div 3 \rightarrow 88 \]

Therefore, $262.5 \div 3.09$ is approximately equal to $88.$

We round both numbers to the nearest whole number: \[ \begin{array}{ccccl} 284.9 & \div & 8.53 \\ \big\downarrow && \big\downarrow \\ \color{blue}285 & \div & \color{blue}9 \end{array} \] Hence, we need to find the value of \[285 \div 9.\] Computing the quotient, we get:

So, the quotient is $31.$

The remainder $6$ is closer to the divisor $9$ than to $0.$ Therefore, to round to the nearest whole number, we must round up:

\[ 285 \div 9 \rightarrow 32. \]

Therefore, $284.9 \div 8.53$ is approximately equal to $32.$
