666188 ÷ 6 
We want to figure out the number of times 666188 can be divided by 6.

Step 1:
6 can be fit into 6 1 times, resulting in a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 6 from 6 leaves us with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 6

On to step 2:
When dividing 6 by 6, we get 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 6 from 6 leaves us with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 6

Let's proceed to step 3:
6 can be fit into 6 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 111.0
The remainder is 0 after subtracting 6 from 6.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 6

Let's proceed to step 4:
When dividing 1 by 6, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 1110.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 6

Moving on to step 5:
When dividing 18 by 6, we get 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 11103.0
The remainder is 0 after subtracting 18 from 18.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 6

Moving on to step 6:
6 goes into 8 1 times with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 111031.0
If we take 6 away from 8, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
6 can be fit into 20 3 times, resulting in a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 111031.3
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
When dividing 20 by 6, we get 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 111031.33
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 111031.33 with a remainder of 0.002.
