Sample Code

(function() {
    "use strict";
    var NUMBER = 'mynumber'; //field code of number field
    var ZEROFILL = 'zerofilled_number'; //field code of text field to set result into

    function zeroFill(value, length) {
        if (value.length >= length) { return value; }
        return (new Array(length).join('0') + value).slice(-length);
    }

    var events = ["app.record.create.change." + NUMBER, 'app.record.edit.change.' + NUMBER];

    kintone.events.on(events, function(event) {
        var record = event.record;
        var changes = event.changes.field;
        var length = 8;  //number of digits for the zero-filled number
        record[ZEROFILL].value = zeroFill(changes.value, length);
        return event;
    });
}());

Notes

Make sure to match the Field code your fields, with the Field code written in the code.
