Let's divide 66631872 by 576
Let's see how many times 576 fits into 66631872.

Going ahead to step 1:
If we divide 6 by 576, 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.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 576

Moving on to step 2:
The number 576 fits into 66 0 times, leaving a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Append the next digit (6) from the dividend to 66 and continue with: 666 / 576

Advancing to step 3:
The number 576 fits into 666 1 times, leaving a remainder of 90.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 576 from 666 to get 90.
Include the next digit (3) from the dividend after 90, then repeat: 903 / 576

Moving on to step 4:
If we divide 903 by 576, we get 1 and a remainder of 327.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 576 from 903, we get 327.
Append the next digit (1) from the dividend to 327 and continue with: 3271 / 576

Advancing to step 5:
If we divide 3271 by 576, we get 5 and a remainder of 391.
The number 5 becomes the next digit in our result. 
Result so far: 115.0
The remainder is 391 after subtracting 2880 from 3271.
Grab the next digit (8) from the dividend, add it to 391, then carry on: 3918 / 576

Step 6:
If we divide 3918 by 576, we get 6 and a remainder of 462.
The next digit of our result is 6. 
Result so far: 1156.0
Subtract 3456 from 3918 to get 462.
Append the next digit (7) from the dividend to 462 and continue with: 4627 / 576

Going ahead to step 7:
4627 divided by 576 is 8 with a remainder of 19.
The next digit of our result is 8. 
Result so far: 11568.0
The remainder is 19 after subtracting 4608 from 4627.
Bring next digit (2) of the dividend behind the 19 and repeat the process: 192 / 576

Going ahead to step 8:
576 goes into 192 0 times with a remainder of 192.
Record the quotient 0 as the next digit in the result. 
Result so far: 115680.0
If we take 0 away from 192, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 9:
576 can be fit into 1920 3 times, resulting in a remainder of 192.
Use 3 as the next digit of our solution. 
Result so far: 115680.3
Subtract 1728 from 1920 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 10:
The number 576 fits into 1920 3 times, leaving a remainder of 192.
Record the quotient 3 as the next digit in the result. 
Result so far: 115680.33
Subtracting 1728 from 1920 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

The final result is 115680.33 with a remainder of 0.192.
