00:00 Solve
00:03 Let's start by dividing the leftmost digit in the dividend
00:08 7 is greater than 1, so we'll bring down the next digit and then divide
00:14 Write the result without remainder above, paying attention to position
00:20 Now multiply the result by the divisor
00:25 Subtract the product from the number
00:30 Now bring down the next digit below and use the same steps
00:36 Divide
00:39 Write the result above
00:43 Multiply the result, subtract
00:48 We got a remainder of 0
00:51 And this is the solution to the problem

Step-by-step solution

To solve this problem, we'll perform long division:

  • **Step 1**: Write down the division as 133÷7 133 \div 7 .
  • **Step 2**: Start with the leading digit or first two digits, 13 13 . Determine how many times 7 can fit into 13. The number 7 fits into 13 a total of 1 time.
  • **Step 3**: Multiply 1 by 7 to get 7, and subtract 7 from 13 to get a remainder of 6.
  • **Step 4**: Bring down the next digit, which is 3, making the number 63.
  • **Step 5**: Determine how many times 7 can fit into 63. The number 7 fits into 63 a total of 9 times.
  • **Step 6**: Multiply 9 by 7 to get 63. Subtract 63 from 63 to obtain a remainder of 0.

Therefore, the division results in 19 19 with no remainder.

The solution to the problem is 19 19 .

Key Points to Remember

Essential concepts to master this topic
  • Process: Divide, multiply, subtract, bring down next digit
  • Technique: 7 goes into 13 once (1×7=7), remainder 6
  • Check: Multiply quotient by divisor: 19×7=133 19 \times 7 = 133

Common Mistakes

Avoid these frequent errors
  • Forgetting to bring down the next digit
    Don't stop after finding 7 goes into 13 once = incomplete quotient of just 1! You miss the remaining digits and get the wrong answer. Always bring down each digit systematically and continue dividing until no digits remain.

FAQ

Everything you need to know about this question

What if 7 doesn't go into 13 evenly?

+

That's normal! When 7 goes into 13, you get 1 with remainder 6. Write down the 1, then bring down the next digit (3) to make 63, and continue dividing.

How do I know when to stop dividing?

+

Stop when you've brought down all digits from the dividend and your remainder is 0. If there's still a remainder after all digits, you either have a remainder or need to add decimal places.

Why do I write the quotient above the dividend?

+

The quotient goes above because it shows the final answer clearly. Each digit of the quotient aligns with the corresponding digit you're working on in the dividend.

What does 'bring down' mean exactly?

+

Bring down means write the next digit from the dividend next to your remainder. So if your remainder is 6 and the next digit is 3, you write 63 and divide 63 by 7.

How can I check if my division is correct?

+

Multiply your quotient by the divisor: 19×7 19 \times 7 . If you get back to your original dividend (133), your division is correct!
