We look at the division of 80569755 by 663 
We want to figure out the number of times 80569755 can be divided by 663.

Moving on to step 1:
8 divided by 663 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 663

Going ahead to step 2:
663 goes into 80 0 times with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Include the next digit (5) from the dividend after 80, then repeat: 805 / 663

Going ahead to step 3:
805 divided by 663 is 1 with a remainder of 142.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 663 from 805 and we're left with 142.
Take the next digit (6) from the dividend and append it to 142, then repeat: 1426 / 663

Advancing to step 4:
1426 divided by 663 is 2 with a remainder of 100.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 1326 from 1426 to get 100.
Bring next digit (9) of the dividend behind the 100 and repeat the process: 1009 / 663

Moving on to step 5:
663 can be fit into 1009 1 times, resulting in a remainder of 346.
Use 1 as the next digit of our solution. 
Result so far: 121.0
The remainder is 346 after subtracting 663 from 1009.
Bring next digit (7) of the dividend behind the 346 and repeat the process: 3467 / 663

Moving on to step 6:
663 goes into 3467 5 times with a remainder of 152.
Put 5 as the next digit of the answer. 
Result so far: 1215.0
Deduct 3315 from 3467 and we're left with 152.
Grab the next digit (5) from the dividend, add it to 152, then carry on: 1525 / 663

Advancing to step 7:
1525 divided by 663 is 2 with a remainder of 199.
Put 2 as the next digit of the answer. 
Result so far: 12152.0
If we take 1326 away from 1525, we end up with 199.
Include the next digit (5) from the dividend after 199, then repeat: 1995 / 663

Going ahead to step 8:
1995 divided by 663 is 3 with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 121523.0
If we subtract 1989 from 1995, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
60 divided by 663 is 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 121523.0
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
When dividing 600 by 663, we get 0 with a remainder of 600.
Use 0 as the next digit of our solution. 
Result so far: 121523.0
Subtracting 0 from 600 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Our division results in 121523.0 with a remaining 0.6.
