We look at the division of 668381 by 87 
Let's see how many times 87 fits into 668381.

Moving on to step 1:
6 divided by 87 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 87

Going ahead to step 2:
66 divided by 87 is 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Fetch the next digit (8) from the dividend, attach it to 66 and continue: 668 / 87

Advancing to step 3:
87 can be fit into 668 7 times, resulting in a remainder of 59.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 609 from 668 and we're left with 59.
Bring next digit (3) of the dividend behind the 59 and repeat the process: 593 / 87

Step 4:
The number 87 fits into 593 6 times, leaving a remainder of 71.
The next digit of our result is 6. 
Result so far: 76.0
The remainder is 71 after subtracting 522 from 593.
Append the next digit (8) from the dividend to 71 and continue with: 718 / 87

On to step 5:
718 divided by 87 is 8 with a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 768.0
If we subtract 696 from 718, we get 22.
Include the next digit (1) from the dividend after 22, then repeat: 221 / 87

On to step 6:
When dividing 221 by 87, we get 2 with a remainder of 47.
Write down 2 as next digit of the result. 
Result so far: 7682.0
Subtract 174 from 221 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.

Advancing to step 7:
87 goes into 470 5 times with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 7682.5
The remainder is 35 after subtracting 435 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 8:
If we divide 350 by 87, we get 4 and a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 7682.54
Subtract 348 from 350 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
87 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 7682.54
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
87 can be fit into 200 2 times, resulting in a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 7682.5402
Deduct 174 from 200 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 11:
The number 87 fits into 260 2 times, leaving a remainder of 86.
The number 2 becomes the next digit in our result. 
Result so far: 7682.54022
If we subtract 174 from 260, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

In conclusion, the division gives 7682.54022 with a balance of 8.6e-05.
