Partial quotient method of division: example using very large numbers

Another example of doing long division using the partial quotient method. Created by Sal Khan.

Want to join the conversation?

• is it okay just to bring each and every number down one at a time or is it faster to use this technique? Cause i did it that way before i watched the video thought i would have the wrong answer i didnt but curious is it faster to do it the way he did?
• It depends on preference. Personally I find the partial quotient method to be much faster. If you choose multiples of 10 (ex 10, 50, 100, 200, 1000) you can just write in the zeros first then the rest is just basic multiplication. It's also a lot easier to estimate. The 'partial quotient' is nothing but a 'divide and conquer' approach. Basically, you divide a big problem into smaller chunks that are easier to process.
• I'm kind of getting better at dividing
• Can I use this method with decimals such as 0.6/4.2?
• can someone explain partial quotients a little better I have a question 1,292 by 31 what are the partial quotients? Please Help. :)
• this is hard.Is their a easy way to do this.
• I don't have room on my paper for all of this 🤣
