1. As 9 doesn't fit in the first digit of 113 you take the fist two digits: How many times fits 9 into 11:
1 time, the first digit of the quotient is 1.
2. Multiply the result of fist part by 9 and subtract it from the first two digits of the divident:
3. Low the third digit of the divident next to the result of the subtraction in step 2 and repeat the steps:
How many times fits 9 into 23: 2
Multiply 9 by 2 and subtract it fro 23
4. To write the answer as a fixed number you use then remainder (in the given division the remainder is 5), the whole part of the mixed number is the quotient (12) and the fraction part has the remainder (5) as numerator and the divisor (9) as denominator.
Then, the answer in mixed form is:
