We're dividing 66643736 by 765 
We want to divide 66643736 by 765.

Moving on to step 1:
The number 765 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in 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 / 765

Step 2:
If we divide 66 by 765, we get 0 and a remainder of 66.
The next digit of our result is 0. 
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 / 765

Advancing to step 3:
When dividing 666 by 765, we get 0 with a remainder of 666.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 666 to get 666.
Bring next digit (4) of the dividend behind the 666 and repeat the process: 6664 / 765

Moving on to step 4:
765 can be fit into 6664 8 times, resulting in a remainder of 544.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 544 after subtracting 6120 from 6664.
Append the next digit (3) from the dividend to 544 and continue with: 5443 / 765

Moving on to step 5:
765 can be fit into 5443 7 times, resulting in a remainder of 88.
Put 7 as the next digit of the answer. 
Result so far: 87.0
If we subtract 5355 from 5443, we get 88.
Include the next digit (7) from the dividend after 88, then repeat: 887 / 765

Advancing to step 6:
If we divide 887 by 765, we get 1 and a remainder of 122.
Record the quotient 1 as the next digit in the result. 
Result so far: 871.0
The remainder is 122 after subtracting 765 from 887.
Include the next digit (3) from the dividend after 122, then repeat: 1223 / 765

Step 7:
The number 765 fits into 1223 1 times, leaving a remainder of 458.
Write down 1 as next digit of the result. 
Result so far: 8711.0
The remainder is 458 after subtracting 765 from 1223.
Include the next digit (6) from the dividend after 458, then repeat: 4586 / 765

Step 8:
765 goes into 4586 5 times with a remainder of 761.
Put 5 as the next digit of the answer. 
Result so far: 87115.0
Subtracting 3825 from 4586 leaves us with 761.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7610, and continue the process.

Let's proceed to step 9:
When dividing 7610 by 765, we get 9 with a remainder of 725.
The number 9 becomes the next digit in our result. 
Result so far: 87115.9
Subtracting 6885 from 7610 leaves us with 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

Advancing to step 10:
When dividing 7250 by 765, we get 9 with a remainder of 365.
The number 9 becomes the next digit in our result. 
Result so far: 87115.99
Subtracting 6885 from 7250 leaves us with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

The quotient of the division is 87115.99, and the remainder is 0.365.
