We're dividing 212666 by 9 
Let's see how many times 9 fits into 212666.

Step 1:
9 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 9

Moving on to step 2:
The number 9 fits into 21 2 times, leaving a remainder of 3.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 18 from 21 to get 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 9

Let's proceed to step 3:
If we divide 32 by 9, we get 3 and a remainder of 5.
The next digit of our result is 3. 
Result so far: 23.0
Deduct 27 from 32 and we're left with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 9

Moving on to step 4:
9 goes into 56 6 times with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 236.0
If we take 54 away from 56, we end up with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 9

On to step 5:
If we divide 26 by 9, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 2362.0
Subtract 18 from 26 to get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 9

Step 6:
86 divided by 9 is 9 with a remainder of 5.
The next digit of our result is 9. 
Result so far: 23629.0
Subtract 81 from 86 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
If we divide 50 by 9, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 23629.5
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
50 divided by 9 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 23629.55
If we take 45 away from 50, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 23629.55, and the remainder is 0.005.
