Moving on to step 1:
666 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 666

On to step 2:
18 divided by 666 is 0 with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Fetch the next digit (8) from the dividend, attach it to 18 and continue: 188 / 666

Step 3:
666 can be fit into 188 0 times, resulting in a remainder of 188.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 188, we end up with 188.
Grab the next digit (6) from the dividend, add it to 188, then carry on: 1886 / 666

Step 4:
666 goes into 1886 2 times with a remainder of 554.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 1332 from 1886 and we're left with 554.
Take the next digit (8) from the dividend and append it to 554, then repeat: 5548 / 666

On to step 5:
The number 666 fits into 5548 8 times, leaving a remainder of 220.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtract 5328 from 5548 to get 220.
Include the next digit (5) from the dividend after 220, then repeat: 2205 / 666

On to step 6:
When dividing 2205 by 666, we get 3 with a remainder of 207.
Use 3 as the next digit of our solution. 
Result so far: 283.0
Subtracting 1998 from 2205 leaves us with 207.
Grab the next digit (4) from the dividend, add it to 207, then carry on: 2074 / 666

Advancing to step 7:
666 can be fit into 2074 3 times, resulting in a remainder of 76.
Put 3 as the next digit of the answer. 
Result so far: 2833.0
Subtract 1998 from 2074 to get 76.
Grab the next digit (2) from the dividend, add it to 76, then carry on: 762 / 666

Moving on to step 8:
If we divide 762 by 666, we get 1 and a remainder of 96.
Write down 1 as next digit of the result. 
Result so far: 28331.0
Subtracting 666 from 762 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 9:
The number 666 fits into 960 1 times, leaving a remainder of 294.
Put 1 as the next digit of the answer. 
Result so far: 28331.1
If we subtract 666 from 960, we get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

On to step 10:
2940 divided by 666 is 4 with a remainder of 276.
The number 4 becomes the next digit in our result. 
Result so far: 28331.14
The remainder is 276 after subtracting 2664 from 2940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Step 11:
If we divide 2760 by 666, we get 4 and a remainder of 96.
The next digit of our result is 4. 
Result so far: 28331.144
If we subtract 2664 from 2760, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Our division results in 28331.144 with a remaining 0.0096.
