Store huge Array of JSON data in MongoDB via Mongoose

Let's say I have an JavaScript Array companyBills and inside of it I have m objects stored in such manner; with m > 100.000 elements.

{key_0:value_0, key_1:value_0_1, key_n:value_0_n},
{key_0:value_1, key_1:value_1_1, key_n:value_1_n},
{key_0:value_m, key_1:value_m_1, key_n:value_m_n}

Now I want to store this in MongoDB via Mongoose, in such a manner:

CompanyBills.create (companyBills, function(err, jellybean, snickers) {
        if(!err) {          
          console.log('Success');
        } else {
          console.log('Error');
        }

However the array companyBills is too huge. Thus I want to store in chunks of 1/100 m. How to split the array companyBills Time-efficiently and store in MongoDB?

(ps: I am also able to use the npm lodash module if of any help)
