We're dividing 26260159 by 666 
Let's see how many times 666 fits into 26260159.

Moving on to step 1:
When dividing 2 by 666, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 666

On to step 2:
The number 666 fits into 26 0 times, leaving a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 26 to get 26.
Take the next digit (2) from the dividend and append it to 26, then repeat: 262 / 666

Let's proceed to step 3:
When dividing 262 by 666, we get 0 with a remainder of 262.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 262 after subtracting 0 from 262.
Take the next digit (6) from the dividend and append it to 262, then repeat: 2626 / 666

Step 4:
666 goes into 2626 3 times with a remainder of 628.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 1998 away from 2626, we end up with 628.
Bring next digit (0) of the dividend behind the 628 and repeat the process: 6280 / 666

Step 5:
The number 666 fits into 6280 9 times, leaving a remainder of 286.
The next digit of our result is 9. 
Result so far: 39.0
The remainder is 286 after subtracting 5994 from 6280.
Fetch the next digit (1) from the dividend, attach it to 286 and continue: 2861 / 666

On to step 6:
If we divide 2861 by 666, we get 4 and a remainder of 197.
The number 4 becomes the next digit in our result. 
Result so far: 394.0
Subtract 2664 from 2861 to get 197.
Fetch the next digit (5) from the dividend, attach it to 197 and continue: 1975 / 666

On to step 7:
666 goes into 1975 2 times with a remainder of 643.
The number 2 becomes the next digit in our result. 
Result so far: 3942.0
Deduct 1332 from 1975 and we're left with 643.
Append the next digit (9) from the dividend to 643 and continue with: 6439 / 666

Let's proceed to step 8:
666 goes into 6439 9 times with a remainder of 445.
Write down 9 as next digit of the result. 
Result so far: 39429.0
If we take 5994 away from 6439, we end up with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

On to step 9:
4450 divided by 666 is 6 with a remainder of 454.
The next digit of our result is 6. 
Result so far: 39429.6
Deduct 3996 from 4450 and we're left with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

On to step 10:
666 can be fit into 4540 6 times, resulting in a remainder of 544.
The next digit of our result is 6. 
Result so far: 39429.66
Deduct 3996 from 4540 and we're left with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

In conclusion, the division gives 39429.66 with a balance of 0.544.
