How to give rest to mysql cpu while process 100000 queriesne by one in laravel?

I am using laravel jobs to do calculation on week end during calculation i need to run almost 100000 queries in a row one by one due to this my mysql server usage reaches 100% i am thinking of to give rest between this process .How i can do this?

Here is the function which i am calling about 25000 times inside loop which has almost 30 queries.

public function calculateConsignmentOneByOne($consignment, $total_consignments, $current_iteration, $user_id, $notify)
{

    if ($consignment->finalize == 0) {

        $type = 'Income';

        if ($consignment->consignment_type == 'pickup' || $consignment->consignment_type == 'return') {
            $delivery_address_id = $consignment->pickup_address;
        } else {
            $delivery_address_id = $consignment->delivery_address;
        }
        $customer_id = $consignment->customer_id;
        $rate_zone = $consignment->rate_zone_id;
        if ($rate_zone == null) {
            $address_to_rate_zone_mapping = getRateZoneByAddressMapping($consignment, $type);

            if ($address_to_rate_zone_mapping != false) {
                $rate_zone = 0;
                $rate_zone = $address_to_rate_zone_mapping;
            } else {
                $rate_zone =   $this->getRateZone($delivery_run_id, $delivery_address_id, $type);
