87189731 ÷ 663 
Let's see how many times 663 fits into 87189731.

Going ahead to step 1:
When dividing 8 by 663, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 663

Step 2:
87 divided by 663 is 0 with a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Include the next digit (1) from the dividend after 87, then repeat: 871 / 663

Going ahead to step 3:
If we divide 871 by 663, we get 1 and a remainder of 208.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 208 after subtracting 663 from 871.
Include the next digit (8) from the dividend after 208, then repeat: 2088 / 663

Step 4:
The number 663 fits into 2088 3 times, leaving a remainder of 99.
Write down 3 as next digit of the result. 
Result so far: 13.0
Deduct 1989 from 2088 and we're left with 99.
Take the next digit (9) from the dividend and append it to 99, then repeat: 999 / 663

Let's proceed to step 5:
If we divide 999 by 663, we get 1 and a remainder of 336.
The number 1 becomes the next digit in our result. 
Result so far: 131.0
Subtract 663 from 999 to get 336.
Include the next digit (7) from the dividend after 336, then repeat: 3367 / 663

On to step 6:
663 can be fit into 3367 5 times, resulting in a remainder of 52.
Write down 5 as next digit of the result. 
Result so far: 1315.0
If we take 3315 away from 3367, we end up with 52.
Append the next digit (3) from the dividend to 52 and continue with: 523 / 663

Step 7:
When dividing 523 by 663, we get 0 with a remainder of 523.
The number 0 becomes the next digit in our result. 
Result so far: 13150.0
If we take 0 away from 523, we end up with 523.
Include the next digit (1) from the dividend after 523, then repeat: 5231 / 663

Moving on to step 8:
663 can be fit into 5231 7 times, resulting in a remainder of 590.
Write down 7 as next digit of the result. 
Result so far: 131507.0
Deduct 4641 from 5231 and we're left with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Step 9:
663 goes into 5900 8 times with a remainder of 596.
Put 8 as the next digit of the answer. 
Result so far: 131507.8
If we subtract 5304 from 5900, we get 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Let's proceed to step 10:
When dividing 5960 by 663, we get 8 with a remainder of 656.
Use 8 as the next digit of our solution. 
Result so far: 131507.88
The remainder is 656 after subtracting 5304 from 5960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Our division results in 131507.88 with a remaining 0.656.
