A 143 divided by 11 equals 13.
To calculate 143 divided by 11 using long division, follow these steps:
- Place the dividend (143) inside the long division symbol, and write the divisor (11) outside the symbol.
- Check how many times 11 can be divided into the first digits of the dividend (1). The result is 1 because 11 * 1 = 11, and this is the largest multiple of 11 that fits into 14 (the first two digits of 143).
- Write the result (1) on top, above the 4 (the first digit of 143).
- Multiply 11 by 1 (the quotient), which equals 11, and write the result under 14.
- Subtract 11 from 14 (14 - 11 = 3).
- Bring down the next digit (3) to form 33.
- Check how many times 11 can be divided into 33. The result is 3 (11 * 3 = 33).
- Write 3 on top, above the 3.
- Multiply 11 by 3, which equals 33, and write the result under 33.
- Subtract 33 from 33 (33 - 33 = 0).
- As there's no remainder and all the digits have been brought down, the final result is 13. So, 143 divided by 11 equals 13.
