85509755 ÷ 663 
We want to figure out the number of times 85509755 can be divided by 663.

Step 1:
When dividing 8 by 663, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 663

Moving on to step 2:
663 goes into 85 0 times with a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Take the next digit (5) from the dividend and append it to 85, then repeat: 855 / 663

Going ahead to step 3:
855 divided by 663 is 1 with a remainder of 192.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 663 from 855 and we're left with 192.
Take the next digit (0) from the dividend and append it to 192, then repeat: 1920 / 663

Going ahead to step 4:
663 goes into 1920 2 times with a remainder of 594.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 1326 from 1920, we get 594.
Bring next digit (9) of the dividend behind the 594 and repeat the process: 5949 / 663

Going ahead to step 5:
663 goes into 5949 8 times with a remainder of 645.
Use 8 as the next digit of our solution. 
Result so far: 128.0
The remainder is 645 after subtracting 5304 from 5949.
Take the next digit (7) from the dividend and append it to 645, then repeat: 6457 / 663

Let's proceed to step 6:
The number 663 fits into 6457 9 times, leaving a remainder of 490.
The number 9 becomes the next digit in our result. 
Result so far: 1289.0
The remainder is 490 after subtracting 5967 from 6457.
Bring next digit (5) of the dividend behind the 490 and repeat the process: 4905 / 663

Advancing to step 7:
If we divide 4905 by 663, we get 7 and a remainder of 264.
Write down 7 as next digit of the result. 
Result so far: 12897.0
The remainder is 264 after subtracting 4641 from 4905.
Take the next digit (5) from the dividend and append it to 264, then repeat: 2645 / 663

Going ahead to step 8:
The number 663 fits into 2645 3 times, leaving a remainder of 656.
Record the quotient 3 as the next digit in the result. 
Result so far: 128973.0
Subtracting 1989 from 2645 leaves us with 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Moving on to step 9:
663 can be fit into 6560 9 times, resulting in a remainder of 593.
The number 9 becomes the next digit in our result. 
Result so far: 128973.9
Deduct 5967 from 6560 and we're left with 593.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5930, and continue the process.

Let's proceed to step 10:
663 can be fit into 5930 8 times, resulting in a remainder of 626.
The next digit of our result is 8. 
Result so far: 128973.98
Subtracting 5304 from 5930 leaves us with 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Advancing to step 11:
When dividing 6260 by 663, we get 9 with a remainder of 293.
Record the quotient 9 as the next digit in the result. 
Result so far: 128973.989
If we take 5967 away from 6260, we end up with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Going ahead to step 12:
The number 663 fits into 2930 4 times, leaving a remainder of 278.
Write down 4 as next digit of the result. 
Result so far: 128973.9894
Subtract 2652 from 2930 to get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Going ahead to step 13:
663 goes into 2780 4 times with a remainder of 128.
The number 4 becomes the next digit in our result. 
Result so far: 128973.98944
Deduct 2652 from 2780 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

In conclusion, the division gives 128973.98944 with a balance of 0.000128.
