66458988 ÷ 765 
Let's see how many times 765 fits into 66458988.

Moving on to step 1:
6 divided by 765 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 765

Moving on to step 2:
If we divide 66 by 765, we get 0 and a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Fetch the next digit (4) from the dividend, attach it to 66 and continue: 664 / 765

On to step 3:
When dividing 664 by 765, we get 0 with a remainder of 664.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 664 to get 664.
Append the next digit (5) from the dividend to 664 and continue with: 6645 / 765

Let's proceed to step 4:
765 goes into 6645 8 times with a remainder of 525.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 525 after subtracting 6120 from 6645.
Append the next digit (8) from the dividend to 525 and continue with: 5258 / 765

Going ahead to step 5:
If we divide 5258 by 765, we get 6 and a remainder of 668.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
The remainder is 668 after subtracting 4590 from 5258.
Bring next digit (9) of the dividend behind the 668 and repeat the process: 6689 / 765

Step 6:
When dividing 6689 by 765, we get 8 with a remainder of 569.
Write down 8 as next digit of the result. 
Result so far: 868.0
Subtracting 6120 from 6689 leaves us with 569.
Bring next digit (8) of the dividend behind the 569 and repeat the process: 5698 / 765

Going ahead to step 7:
If we divide 5698 by 765, we get 7 and a remainder of 343.
The next digit of our result is 7. 
Result so far: 8687.0
If we subtract 5355 from 5698, we get 343.
Append the next digit (8) from the dividend to 343 and continue with: 3438 / 765

Going ahead to step 8:
765 goes into 3438 4 times with a remainder of 378.
Put 4 as the next digit of the answer. 
Result so far: 86874.0
The remainder is 378 after subtracting 3060 from 3438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Moving on to step 9:
3780 divided by 765 is 4 with a remainder of 720.
The number 4 becomes the next digit in our result. 
Result so far: 86874.4
Subtracting 3060 from 3780 leaves us with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Moving on to step 10:
765 goes into 7200 9 times with a remainder of 315.
The next digit of our result is 9. 
Result so far: 86874.49
If we subtract 6885 from 7200, we get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Step 11:
When dividing 3150 by 765, we get 4 with a remainder of 90.
The next digit of our result is 4. 
Result so far: 86874.494
The remainder is 90 after subtracting 3060 from 3150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 12:
The number 765 fits into 900 1 times, leaving a remainder of 135.
The number 1 becomes the next digit in our result. 
Result so far: 86874.4941
Deduct 765 from 900 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 13:
765 can be fit into 1350 1 times, resulting in a remainder of 585.
Record the quotient 1 as the next digit in the result. 
Result so far: 86874.49411
Subtract 765 from 1350 to get 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

In conclusion, the division gives 86874.49411 with a balance of 0.000585.
