We look at the division of 669535 by 87 
We're looking to find how many times 87 goes into 669535.

Let's proceed to step 1:
6 divided by 87 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 87

Let's proceed to step 2:
87 goes into 66 0 times with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Fetch the next digit (9) from the dividend, attach it to 66 and continue: 669 / 87

On to step 3:
When dividing 669 by 87, we get 7 with a remainder of 60.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 609 from 669 to get 60.
Include the next digit (5) from the dividend after 60, then repeat: 605 / 87

Step 4:
605 divided by 87 is 6 with a remainder of 83.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
If we subtract 522 from 605, we get 83.
Bring next digit (3) of the dividend behind the 83 and repeat the process: 833 / 87

On to step 5:
When dividing 833 by 87, we get 9 with a remainder of 50.
The next digit of our result is 9. 
Result so far: 769.0
Subtracting 783 from 833 leaves us with 50.
Grab the next digit (5) from the dividend, add it to 50, then carry on: 505 / 87

Moving on to step 6:
When dividing 505 by 87, we get 5 with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 7695.0
Deduct 435 from 505 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 7:
When dividing 700 by 87, we get 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 7695.8
If we subtract 696 from 700, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
87 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 7695.8
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
400 divided by 87 is 4 with a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 7695.804
Subtracting 348 from 400 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 10:
The number 87 fits into 520 5 times, leaving a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 7695.8045
The remainder is 85 after subtracting 435 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 11:
850 divided by 87 is 9 with a remainder of 67.
The number 9 becomes the next digit in our result. 
Result so far: 7695.80459
Deduct 783 from 850 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 12:
The number 87 fits into 670 7 times, leaving a remainder of 61.
The number 7 becomes the next digit in our result. 
Result so far: 7695.804597
Subtract 609 from 670 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 13:
87 can be fit into 610 7 times, resulting in a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 7695.8045977
Subtracting 609 from 610 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 7695.8045977 with a balance of 1e-08.
