To solve this problem, we'll use the long division method to divide by :
1. Consider the first digit of the dividend, . How many times does go into ? It fits 1 time.
2. Write in the quotient and subtract from the digit to get . Next, bring down the next digit, which is , making the number .
3. Determine how many times fits into . It fits no times, so write in the quotient, resulting in in the quotient so far. Bring down the next digit , making it .
4. How many times does go into ? It fits 10 times. Write a in the quotient next to the existing one, making .
5. Subtract , resulting in . Bring down the next digit , making it .
6. How many times does go into ? It fits 2 times. Write in the quotient, yielding a final quotient of .
Subtract from , resulting in a remainder of , indicating division is complete with no remainder.
Therefore, the quotient when is divided by is .
