66112446 divided by 221 
Our goal is to divide 66112446 by 221.

Going ahead to step 1:
6 divided by 221 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 221

Let's proceed to step 2:
221 can be fit into 66 0 times, resulting in a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Bring next digit (1) of the dividend behind the 66 and repeat the process: 661 / 221

On to step 3:
221 can be fit into 661 2 times, resulting in a remainder of 219.
The next digit of our result is 2. 
Result so far: 2.0
If we take 442 away from 661, we end up with 219.
Bring next digit (1) of the dividend behind the 219 and repeat the process: 2191 / 221

Advancing to step 4:
The number 221 fits into 2191 9 times, leaving a remainder of 202.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
If we subtract 1989 from 2191, we get 202.
Append the next digit (2) from the dividend to 202 and continue with: 2022 / 221

On to step 5:
2022 divided by 221 is 9 with a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 299.0
Deduct 1989 from 2022 and we're left with 33.
Grab the next digit (4) from the dividend, add it to 33, then carry on: 334 / 221

Advancing to step 6:
The number 221 fits into 334 1 times, leaving a remainder of 113.
Use 1 as the next digit of our solution. 
Result so far: 2991.0
If we take 221 away from 334, we end up with 113.
Include the next digit (4) from the dividend after 113, then repeat: 1134 / 221

Moving on to step 7:
If we divide 1134 by 221, we get 5 and a remainder of 29.
Put 5 as the next digit of the answer. 
Result so far: 29915.0
The remainder is 29 after subtracting 1105 from 1134.
Fetch the next digit (6) from the dividend, attach it to 29 and continue: 296 / 221

Step 8:
296 divided by 221 is 1 with a remainder of 75.
Record the quotient 1 as the next digit in the result. 
Result so far: 299151.0
If we take 221 away from 296, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 9:
The number 221 fits into 750 3 times, leaving a remainder of 87.
Write down 3 as next digit of the result. 
Result so far: 299151.3
If we subtract 663 from 750, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 10:
When dividing 870 by 221, we get 3 with a remainder of 207.
Write down 3 as next digit of the result. 
Result so far: 299151.33
If we take 663 away from 870, we end up with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

The final result is 299151.33 with a remainder of 0.207.
