 Divides a number by the specified number.
 
-The result is rounded down to the nearest integer (that is, the [floor]({{ "/filters/floor" | prepend: site.baseurl }})).
+The result is rounded down to the nearest integer (that is, the [floor]({{ "/filters/floor" | prepend: site.baseurl }})) if the divisor is an integer.

+### Controlling rounding
+
+`divided_by` produces a result of the same type as the divisor — that is, if you divide by an integer, the result will be an integer. If you divide by a float (a number with a decimal in it), the result will be a float.
+
+For example, here the divisor is an integer:
+
+<p class="code-label">Input</p>
+{% raw %}
+``` liquid
+{{ 20 | divided_by: 7 }}
+```
+{% endraw %}
+
+<p class="code-label">Output</p>
+``` text
+{{ 20 | divided_by: 7 }}
+```
+
+Here it is a float:
+
+<p class="code-label">Input</p>
+{% raw %}
+``` liquid
+{{ 20 | divided_by: 7.0 }}
+```
+{% endraw %}
+
+<p class="code-label">Output</p>
+``` text
+{{ 20 | divided_by: 7.0 }}
+```
+
+### Changing variable types
+
+You might want to use a variable as a divisor, in which case you can't simply add `.0` to convert it to a float. In these cases, you can `assign` a version of your variable converted to a float using the `times` filter:
+
+In this example, we're dividing by a variable that contains an integer, so we get an integer:
+
+<p class="code-label">Input</p>
+{% raw %}
+``` liquid
+{% assign my_integer = 7 %}
+{{ 20 | divided_by: my_integer }}
+```
+{% endraw %}
+
+
+<p class="code-label">Output</p>
+``` text
+{% assign my_integer = 7 %}
+{{ 20 | divided_by: my_integer }}
+```
+
+Here, we [multiply]({{ site.baseurl}}/filters/times) the variable by `1.0` to get a float, then divide by the float instead:
+
+<p class="code-label">Input</p>
+{% raw %}
+``` liquid
+{% assign my_integer = 7 %}
+{% assign my_float = my_integer | times: 1.0 %}
+{{ 20 | divided_by: my_float }}
+```
+{% endraw %}
+
+
+<p class="code-label">Output</p>
+``` text
+{% assign my_integer = 7 %}
+{% assign my_float = my_integer | times: 1.0 %}
+{{ 20 | divided_by: my_float }}
+```
