We look at the division of 663895 by 87 
Let's see how many times 87 fits into 663895.

Moving on to step 1:
The number 87 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 87

Let's proceed to step 2:
87 can be fit into 66 0 times, resulting in a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Take the next digit (3) from the dividend and append it to 66, then repeat: 663 / 87

On to step 3:
The number 87 fits into 663 7 times, leaving a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 609 away from 663, we end up with 54.
Take the next digit (8) from the dividend and append it to 54, then repeat: 548 / 87

Step 4:
When dividing 548 by 87, we get 6 with a remainder of 26.
The next digit of our result is 6. 
Result so far: 76.0
Subtracting 522 from 548 leaves us with 26.
Fetch the next digit (9) from the dividend, attach it to 26 and continue: 269 / 87

Advancing to step 5:
When dividing 269 by 87, we get 3 with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 763.0
If we take 261 away from 269, we end up with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 87

Going ahead to step 6:
If we divide 85 by 87, we get 0 and a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 7630.0
The remainder is 85 after subtracting 0 from 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 7:
87 can be fit into 850 9 times, resulting in a remainder of 67.
Use 9 as the next digit of our solution. 
Result so far: 7630.9
The remainder is 67 after subtracting 783 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 8:
87 can be fit into 670 7 times, resulting in a remainder of 61.
The number 7 becomes the next digit in our result. 
Result so far: 7630.97
If we subtract 609 from 670, we 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.

On to step 9:
When dividing 610 by 87, we get 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 7630.977
Deduct 609 from 610 and we're left 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.

The final outcome is 7630.977, with a leftover of 0.0001.
