We look at the division of 2660454 by 309 
We want to figure out the number of times 2660454 can be divided by 309.

On to step 1:
309 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 309

On to step 2:
If we divide 26 by 309, we get 0 and a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 26 after subtracting 0 from 26.
Append the next digit (6) from the dividend to 26 and continue with: 266 / 309

Step 3:
309 can be fit into 266 0 times, resulting in a remainder of 266.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 266 leaves us with 266.
Fetch the next digit (0) from the dividend, attach it to 266 and continue: 2660 / 309

On to step 4:
The number 309 fits into 2660 8 times, leaving a remainder of 188.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 2472 from 2660, we get 188.
Append the next digit (4) from the dividend to 188 and continue with: 1884 / 309

Step 5:
The number 309 fits into 1884 6 times, leaving a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
Deduct 1854 from 1884 and we're left with 30.
Bring next digit (5) of the dividend behind the 30 and repeat the process: 305 / 309

Let's proceed to step 6:
309 goes into 305 0 times with a remainder of 305.
Write down 0 as next digit of the result. 
Result so far: 860.0
If we take 0 away from 305, we end up with 305.
Grab the next digit (4) from the dividend, add it to 305, then carry on: 3054 / 309

Advancing to step 7:
309 goes into 3054 9 times with a remainder of 273.
The next digit of our result is 9. 
Result so far: 8609.0
If we take 2781 away from 3054, we end up with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Advancing to step 8:
309 can be fit into 2730 8 times, resulting in a remainder of 258.
The number 8 becomes the next digit in our result. 
Result so far: 8609.8
Subtract 2472 from 2730 to get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Let's proceed to step 9:
The number 309 fits into 2580 8 times, leaving a remainder of 108.
Write down 8 as next digit of the result. 
Result so far: 8609.88
If we take 2472 away from 2580, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

The final outcome is 8609.88, with a leftover of 0.108.
