Steps to Divide In Detail
Once your problem is set up, it's time to start dividing. Using multiplication, determine the number of times your divisor will go into the first portion of your dividend.
Example: 840 / 8
Check the first digit of your dividend. Can your divisor go into the first digit at least once? It does not have to divide into it equally. In this case, 8 will divide into 8. Using the house set up, place a 1 over the 8 in 840.
Multiply your divisor by the first part of your quotient. Place the answer under the 8 in 840. Subtract your result. In this case, the result is 0.
Bring down the next available digit of your dividend. This would leave you with 04, but you only need to keep the 4.
Determine if 8 will divide into 4. Since it will not, place a 0 over the 4. Multiply 0 by 8 and place the resulting 0 under the 4. Subtract to get the result of 4.
Bring down your next digit. You should now have 40. Determine if 8 will go into 40. Since 40 is larger than 8, the answer is yes. Use your multiplication rules and tables to determine the maximum number of times 8 goes into 40. The answer is 5.
Place 5 over the 0 of 840. Multiply 5 by 8 and place the answer under the 40. Subtract 40 from 40. The result is 0. Your final quotient will be 105.
When you have run out of digits and your final subtraction result is not zero, you must either start using decimal places, which adds zeros to your number or place the remaining result as a remainder. For instance, if the example above had been 845 / 8, you would have subtracted 40 from 45, resulting in a remainder of 5. To state this result, use the remainder symbol R. The quotient would be 105 R 5.
