The question is, why are you trying to get the value using what you posted.

Here’s an explanation of

[field_5492be0701cb6]  // field key of recipe_sections
[1]                    // row 1
[field_5492be5d01cb8]  // field key of section_steps
[0]                    // row 0
[field_5492c04b01cbb]  // field key of step_ingredients
[0]                    // row 0
[field_5492c13601cbf]  // field key of quantity

You can convert the field key to the field name this way

$field = get_field_object($field_key);
$field_name = $field['name'];

Your field has 4 levels, a repeater or flex field, two nested repeaters or flex fields and whatever quantity is. ACF creates meta keys for repeaters like this:

"{$field_name}_{$row}_{$field_name}_{$row}_{$field_name}_{$row}_{$field_name}"
