We look at the division of 555040 by 87 
We want to figure out the number of times 555040 can be divided by 87.

On to step 1:
87 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 87

On to step 2:
87 goes into 55 0 times with a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Grab the next digit (5) from the dividend, add it to 55, then carry on: 555 / 87

Step 3:
87 goes into 555 6 times with a remainder of 33.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 33 after subtracting 522 from 555.
Bring next digit (0) of the dividend behind the 33 and repeat the process: 330 / 87

Moving on to step 4:
87 can be fit into 330 3 times, resulting in a remainder of 69.
Use 3 as the next digit of our solution. 
Result so far: 63.0
If we subtract 261 from 330, we get 69.
Fetch the next digit (4) from the dividend, attach it to 69 and continue: 694 / 87

Moving on to step 5:
When dividing 694 by 87, we get 7 with a remainder of 85.
Use 7 as the next digit of our solution. 
Result so far: 637.0
Subtracting 609 from 694 leaves us with 85.
Take the next digit (0) from the dividend and append it to 85, then repeat: 850 / 87

Step 6:
87 can be fit into 850 9 times, resulting in a remainder of 67.
Put 9 as the next digit of the answer. 
Result so far: 6379.0
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 7:
The number 87 fits into 670 7 times, leaving a remainder of 61.
Record the quotient 7 as the next digit in the result. 
Result so far: 6379.7
If we take 609 away from 670, we end up with 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 8:
610 divided by 87 is 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 6379.77
Subtract 609 from 610 to get 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 6379.77, with a leftover of 0.001.
