How can we divide all values in a column by some number in a DataFrame?

## Example scenario

Suppose we’re dealing with a DataFrame `df` that looks something like this.

``````   A      B
0  11.11  0.22
1  33.33  0.44
``````

We want to divide every number in column `A` by `100`.

``````   A       B
0  0.1111  0.22
1  0.3333  0.44
``````

## Divide column by a number

We can divide by a number using `div()`.

``````df['A'] = df['A'].div(100)
df['A'] = (df['A'] / 100) # Same output
``````

Revise the code and make it more robust with proper test case and check an error there before implementing into a production environment.
