Calculates and formats a quotient based on a divisor and dividend.

Unlike ColumnCallbackAddColumnPercentage's,
version of this method, this method will return 100% if the past
value of a metric is 0, and the current value is not 0. For a
value representative of an evolution, this makes sense.

@param int|float $value The dividend.
@param int|float $divisor
@return string
