We look at the division of 66907892 by 239 
Our goal is to divide 66907892 by 239.

Moving on to step 1:
If we divide 6 by 239, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 239

On to step 2:
If we divide 66 by 239, we get 0 and a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Append the next digit (9) from the dividend to 66 and continue with: 669 / 239

Advancing to step 3:
When dividing 669 by 239, we get 2 with a remainder of 191.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 478 from 669 to get 191.
Take the next digit (0) from the dividend and append it to 191, then repeat: 1910 / 239

Advancing to step 4:
1910 divided by 239 is 7 with a remainder of 237.
The next digit of our result is 7. 
Result so far: 27.0
Subtract 1673 from 1910 to get 237.
Bring next digit (7) of the dividend behind the 237 and repeat the process: 2377 / 239

Going ahead to step 5:
239 goes into 2377 9 times with a remainder of 226.
The number 9 becomes the next digit in our result. 
Result so far: 279.0
Subtracting 2151 from 2377 leaves us with 226.
Include the next digit (8) from the dividend after 226, then repeat: 2268 / 239

Moving on to step 6:
The number 239 fits into 2268 9 times, leaving a remainder of 117.
Write down 9 as next digit of the result. 
Result so far: 2799.0
Deduct 2151 from 2268 and we're left with 117.
Bring next digit (9) of the dividend behind the 117 and repeat the process: 1179 / 239

On to step 7:
The number 239 fits into 1179 4 times, leaving a remainder of 223.
Write down 4 as next digit of the result. 
Result so far: 27994.0
Subtracting 956 from 1179 leaves us with 223.
Include the next digit (2) from the dividend after 223, then repeat: 2232 / 239

Advancing to step 8:
2232 divided by 239 is 9 with a remainder of 81.
Use 9 as the next digit of our solution. 
Result so far: 279949.0
If we take 2151 away from 2232, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 9:
810 divided by 239 is 3 with a remainder of 93.
Record the quotient 3 as the next digit in the result. 
Result so far: 279949.3
Deduct 717 from 810 and we're left with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Step 10:
239 can be fit into 930 3 times, resulting in a remainder of 213.
The number 3 becomes the next digit in our result. 
Result so far: 279949.33
Subtract 717 from 930 to get 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

After the division, we end up with 279949.33 and a remainder of 0.213.
