87102987 ÷ 881 
Our goal is to divide 87102987 by 881.

Going ahead to step 1:
If we divide 8 by 881, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 881

Going ahead to step 2:
881 can be fit into 87 0 times, resulting in a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Fetch the next digit (1) from the dividend, attach it to 87 and continue: 871 / 881

Step 3:
If we divide 871 by 881, we get 0 and a remainder of 871.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 871 and we're left with 871.
Fetch the next digit (0) from the dividend, attach it to 871 and continue: 8710 / 881

Moving on to step 4:
881 can be fit into 8710 9 times, resulting in a remainder of 781.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 7929 from 8710 leaves us with 781.
Bring next digit (2) of the dividend behind the 781 and repeat the process: 7812 / 881

Moving on to step 5:
881 goes into 7812 8 times with a remainder of 764.
Write down 8 as next digit of the result. 
Result so far: 98.0
Deduct 7048 from 7812 and we're left with 764.
Bring next digit (9) of the dividend behind the 764 and repeat the process: 7649 / 881

Moving on to step 6:
881 goes into 7649 8 times with a remainder of 601.
Record the quotient 8 as the next digit in the result. 
Result so far: 988.0
Subtract 7048 from 7649 to get 601.
Grab the next digit (8) from the dividend, add it to 601, then carry on: 6018 / 881

On to step 7:
6018 divided by 881 is 6 with a remainder of 732.
Write down 6 as next digit of the result. 
Result so far: 9886.0
If we take 5286 away from 6018, we end up with 732.
Append the next digit (7) from the dividend to 732 and continue with: 7327 / 881

Advancing to step 8:
The number 881 fits into 7327 8 times, leaving a remainder of 279.
Use 8 as the next digit of our solution. 
Result so far: 98868.0
If we take 7048 away from 7327, we end up with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Let's proceed to step 9:
881 goes into 2790 3 times with a remainder of 147.
Put 3 as the next digit of the answer. 
Result so far: 98868.3
The remainder is 147 after subtracting 2643 from 2790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

On to step 10:
881 can be fit into 1470 1 times, resulting in a remainder of 589.
Put 1 as the next digit of the answer. 
Result so far: 98868.31
If we subtract 881 from 1470, we get 589.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5890, and continue the process.

Step 11:
The number 881 fits into 5890 6 times, leaving a remainder of 604.
Use 6 as the next digit of our solution. 
Result so far: 98868.316
Subtract 5286 from 5890 to get 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Step 12:
881 can be fit into 6040 6 times, resulting in a remainder of 754.
The number 6 becomes the next digit in our result. 
Result so far: 98868.3166
The remainder is 754 after subtracting 5286 from 6040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

The final outcome is 98868.3166, with a leftover of 0.00754.
