Answer 1

Since we are talking about money, normally a few cents different doesn't matter as long as the total adds up correctly. So if you don't mind one payment possibly being a few cents greater than the rest, here is a really simple solution for installment payments.

function CalculateInstallments(total, installments) {
  // Calculate Installment Payments
  var pennies = total * 100;
  var remainder = pennies % installments;
  var otherPayments = (pennies - remainder) / installments;
  var firstPayment = otherPayments + remainder;

  for (var i = 0; i < installments; i++) {
    if (i == 0) {
      console.log("first payment = ", firstPayment / 100);
    } else {
      console.log("next payment = ", otherPayments / 100);
    }
  }
}

Since you said you wanted the highest payment at the end you would want to modify the if statement in the for loop: if (i==installments-1) { //last payment }
