We look at the division of 866447 by 66 
Our goal is to divide 866447 by 66.

Moving on to step 1:
If we divide 8 by 66, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 66

Step 2:
The number 66 fits into 86 1 times, leaving a remainder of 20.
The next digit of our result is 1. 
Result so far: 1.0
If we take 66 away from 86, we end up with 20.
Bring next digit (6) of the dividend behind the 20 and repeat the process: 206 / 66

Moving on to step 3:
66 can be fit into 206 3 times, resulting in a remainder of 8.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 198 from 206, we get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 66

On to step 4:
If we divide 84 by 66, we get 1 and a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 131.0
The remainder is 18 after subtracting 66 from 84.
Include the next digit (4) from the dividend after 18, then repeat: 184 / 66

Moving on to step 5:
66 can be fit into 184 2 times, resulting in a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 1312.0
Subtract 132 from 184 to get 52.
Append the next digit (7) from the dividend to 52 and continue with: 527 / 66

Step 6:
If we divide 527 by 66, we get 7 and a remainder of 65.
Write down 7 as next digit of the result. 
Result so far: 13127.0
Subtracting 462 from 527 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 7:
66 goes into 650 9 times with a remainder of 56.
The number 9 becomes the next digit in our result. 
Result so far: 13127.9
If we take 594 away from 650, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 8:
When dividing 560 by 66, we get 8 with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 13127.98
The remainder is 32 after subtracting 528 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 9:
When dividing 320 by 66, we get 4 with a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 13127.984
The remainder is 56 after subtracting 264 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 10:
560 divided by 66 is 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 13127.9848
Deduct 528 from 560 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 11:
The number 66 fits into 320 4 times, leaving a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 13127.98484
The remainder is 56 after subtracting 264 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 12:
If we divide 560 by 66, we get 8 and a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 13127.984848
The remainder is 32 after subtracting 528 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 13:
The number 66 fits into 320 4 times, leaving a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 13127.9848484
Deduct 264 from 320 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 14:
The number 66 fits into 560 8 times, leaving a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 13127.98484848
If we subtract 528 from 560, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 13127.98484848 and a remainder of 3.2e-08.
