221208 ÷ 12 
We want to figure out the number of times 221208 can be divided by 12.

Going ahead to step 1:
If we divide 2 by 12, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 12

Step 2:
12 can be fit into 22 1 times, resulting in a remainder of 10.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 12 from 22 leaves us with 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 12

Let's proceed to step 3:
101 divided by 12 is 8 with a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we take 96 away from 101, we end up with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 12

Step 4:
52 divided by 12 is 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 184.0
The remainder is 4 after subtracting 48 from 52.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 12

Moving on to step 5:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 1843.0
The remainder is 4 after subtracting 36 from 40.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 12

Step 6:
12 can be fit into 48 4 times, resulting in a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 18434.0
The remainder is 0 after subtracting 48 from 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
12 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 18434.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
12 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 18434.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 18434.0 with a remainder of 0.0.
