We look at the division of 859661 by 87 
Let's see how many times 87 fits into 859661.

Going ahead to step 1:
When dividing 8 by 87, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 87

Step 2:
87 goes into 85 0 times with a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Bring next digit (9) of the dividend behind the 85 and repeat the process: 859 / 87

Step 3:
87 can be fit into 859 9 times, resulting in a remainder of 76.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 783 away from 859, we end up with 76.
Take the next digit (6) from the dividend and append it to 76, then repeat: 766 / 87

On to step 4:
When dividing 766 by 87, we get 8 with a remainder of 70.
The next digit of our result is 8. 
Result so far: 98.0
The remainder is 70 after subtracting 696 from 766.
Take the next digit (6) from the dividend and append it to 70, then repeat: 706 / 87

Going ahead to step 5:
When dividing 706 by 87, we get 8 with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 988.0
Subtracting 696 from 706 leaves us with 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 87

On to step 6:
87 can be fit into 101 1 times, resulting in a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 9881.0
The remainder is 14 after subtracting 87 from 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
If we divide 140 by 87, we get 1 and a remainder of 53.
Use 1 as the next digit of our solution. 
Result so far: 9881.1
The remainder is 53 after subtracting 87 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 8:
530 divided by 87 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 9881.16
If we subtract 522 from 530, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
87 can be fit into 80 0 times, resulting in a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 9881.16
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 10:
87 can be fit into 800 9 times, resulting in a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 9881.1609
If we take 783 away from 800, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 11:
87 can be fit into 170 1 times, resulting in a remainder of 83.
Put 1 as the next digit of the answer. 
Result so far: 9881.16091
The remainder is 83 after subtracting 87 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 12:
The number 87 fits into 830 9 times, leaving a remainder of 47.
Record the quotient 9 as the next digit in the result. 
Result so far: 9881.160919
Subtract 783 from 830 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 13:
87 can be fit into 470 5 times, resulting in a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 9881.1609195
If we subtract 435 from 470, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 14:
87 goes into 350 4 times with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 9881.16091954
The remainder is 2 after subtracting 348 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 9881.16091954 with a balance of 2e-09.
