Dividing A 3-Digit Number by a 1-Digit Number
Hop in because we are going for a ride. This ride isn’t your usual road trip. It's a journey down division lane.
Our first pit stop is to set up our equation, 525 divided by 3.
Draw the division symbol and write the dividend inside the symbol (to the right of the vertical line and below the horizontal line of the symbol) and the divisor on this side (to the left of the vertical of the division symbol). Write the answer on the top (above the horizontal line of the division symbol).
When using long division divide digit by digit from left to right.
Begin by dividing 5 by 3. How many 3s will it take to make 5?
Since we can only have one 3 without going above 5 we will write 1 at the top.
The answer of 1 needs to go directly above the digit that we are dividing so we will write it above the 5.
Now, multiply 1 by 3 and write the answer here (below the digit that we are dividing, so we will write it below the 5). Subtract 3 from 5 to get 2 (place the 2 directly below the 3).
Are we there yet? Hang in there. We're getting closer.
It's time to move to the next digit.
Bring a copy of the next digit down right beside the remainder, which is 2.
Now, divide the number 22 by the number 3.
How many 3s go into 22? We can have seven threes which equals 21. Write seven above the 2 at the top.
Seven times three equals twenty one so write 21 below the 22 and subtract to get 1.
Finally, bring down the 5 beside the 1. 3 goes into 15, 5 times. Write the number 5 above the 5.
Are we there yet? Not yet, but we’re close!
There are five threes in 15. 15 minus 15 equals 0. This means that there is no remainder.
So, 525 divided by 3 is 175.
Now are we there? Yes we are!
Long division is like a long car ride. There are lots of stops but once you get rolling, it’s a breeze!
