About the Redesign

If you visited this site prior to September 15th, 2018, you've no doubt noticed that I've since launched a complete redesign of the website.

If you're not happy with the new design, I sincerely apologize. I would have preferred to keep the old desktop design, but considering the majority of my site's users are now accessing the site from small-screen, touch-enabled, mobile devices, and considering Google is now penalizing websites for not being mobile/thumb friendly, I was left with no choice but to switch to a responsive, mobile-first design.

The good news is that now that I have combined the three separate versions of the site (mobile, desktop, and ad-free member) into a single design, this will free up a ton of my time for working to make the mobile-optimized calculators more desktop/laptop friendly. In fact, some of the redesigned calculators already offer a desktop-optimized form that becomes visible when you increase the width setting of the calculator (within the "Calculator Preferences" expandable panel).

Thank you in advance for your help and patience as I work to improve the redesign.

Long Division Calculator

This calculator will not only perform long division, but it will also show and explain each step it took to solve the problem. The calculated results even include a chart showing multiples of the divisor so you can learn your math facts while you are doing your long division practice. The Learn tab includes:

How to do long division when dividing...

  • Whole numbers with no remainder.
  • Whole numbers with whole remainder.
  • Decimal numbers with no remainder.
  • Decimal numbers with decimal remainder.

Selected Data Record:

A Data Record is a set of calculator entries that are stored in your web browser's Local Storage. If a Data Record is currently selected in the "Data" tab, this line will list the name you gave to that data record. If no data record is selected, or you have no entries stored for this calculator, the line will display "None".

Enter the divisor in the left-hand field on the line below (number greater than zero). The divisor is the number being divided into another number. If the divisor you enter is greater than the dividend, the result will be a decimal number less than 1.



Enter the dividend in the right-hand field on the line below (number greater than zero). The dividend is the number being divided by another number.

Long division quotient:

This is the result the long division calculator stopped at. Please double check this result with the result on the next line.

Calculated:Calculated quotient:Calculated division quotient:Calculated division quotient:

Calculated division quotient:

This is the result you would likely get if you used a standard calculator for the division. This result is provided as a means to check the long division result for accuracy. Note that if the result contains more than 16 digits the last digit(s) is likely rounded.

Whole num:Whole number:Whole number portion of quotient:Whole number portion of quotient:

Whole number portion of quotient:

This is the whole number portion of the quotient. The quotient is the result of dividing one number by another.



This is what is left after multiplying the whole number portion of the quotient by the divisor, and then subtracting that result from the dividend.

If you would like to save the current entries to the secure database, tap or click on the Data tab, select "New Data Record", give the data record a name, then tap or click the Save button. To save changes to previously saved entries, simply tap the Save button. Please select and "Clear" any data records you no longer need.
