We're dividing 266690 by 3 
We want to figure out the number of times 266690 can be divided by 3.

Let's proceed to step 1:
3 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 3

Moving on to step 2:
3 can be fit into 26 8 times, resulting in a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 24 from 26 and we're left with 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 3

Moving on to step 3:
When dividing 26 by 3, we get 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
Deduct 24 from 26 and we're left with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 3

Let's proceed to step 4:
3 goes into 26 8 times with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 888.0
The remainder is 2 after subtracting 24 from 26.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 3

Let's proceed to step 5:
3 goes into 29 9 times with a remainder of 2.
The next digit of our result is 9. 
Result so far: 8889.0
Deduct 27 from 29 and we're left with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 3

Going ahead to step 6:
The number 3 fits into 20 6 times, leaving a remainder of 2.
The next digit of our result is 6. 
Result so far: 88896.0
Deduct 18 from 20 and we're left 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.

Going ahead to step 7:
20 divided by 3 is 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 88896.6
If we subtract 18 from 20, we 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.

Advancing to step 8:
If we divide 20 by 3, we get 6 and a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 88896.66
Subtracting 18 from 20 leaves us 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.

After the division, we end up with 88896.66 and a remainder of 0.002.
