66893006 ÷ 309 
Let's see how many times 309 fits into 66893006.

Advancing to step 1:
309 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 309

Step 2:
66 divided by 309 is 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Grab the next digit (8) from the dividend, add it to 66, then carry on: 668 / 309

Step 3:
668 divided by 309 is 2 with a remainder of 50.
The next digit of our result is 2. 
Result so far: 2.0
If we take 618 away from 668, we end up with 50.
Bring next digit (9) of the dividend behind the 50 and repeat the process: 509 / 309

Advancing to step 4:
309 goes into 509 1 times with a remainder of 200.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
The remainder is 200 after subtracting 309 from 509.
Bring next digit (3) of the dividend behind the 200 and repeat the process: 2003 / 309

Let's proceed to step 5:
If we divide 2003 by 309, we get 6 and a remainder of 149.
The number 6 becomes the next digit in our result. 
Result so far: 216.0
If we subtract 1854 from 2003, we get 149.
Append the next digit (0) from the dividend to 149 and continue with: 1490 / 309

Going ahead to step 6:
When dividing 1490 by 309, we get 4 with a remainder of 254.
Put 4 as the next digit of the answer. 
Result so far: 2164.0
Subtract 1236 from 1490 to get 254.
Grab the next digit (0) from the dividend, add it to 254, then carry on: 2540 / 309

Advancing to step 7:
The number 309 fits into 2540 8 times, leaving a remainder of 68.
Write down 8 as next digit of the result. 
Result so far: 21648.0
The remainder is 68 after subtracting 2472 from 2540.
Bring next digit (6) of the dividend behind the 68 and repeat the process: 686 / 309

On to step 8:
309 can be fit into 686 2 times, resulting in a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 216482.0
If we take 618 away from 686, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 9:
When dividing 680 by 309, we get 2 with a remainder of 62.
Record the quotient 2 as the next digit in the result. 
Result so far: 216482.2
Subtracting 618 from 680 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 10:
If we divide 620 by 309, we get 2 and a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 216482.22
Subtract 618 from 620 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.

After the division, we end up with 216482.22 and a remainder of 0.002.
