We look at the division of 517437 by 87 
Let's see how many times 87 fits into 517437.

Step 1:
87 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 87

Let's proceed to step 2:
The number 87 fits into 51 0 times, leaving a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Take the next digit (7) from the dividend and append it to 51, then repeat: 517 / 87

Advancing to step 3:
87 can be fit into 517 5 times, resulting in a remainder of 82.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 435 from 517 and we're left with 82.
Take the next digit (4) from the dividend and append it to 82, then repeat: 824 / 87

Moving on to step 4:
If we divide 824 by 87, we get 9 and a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 59.0
Subtracting 783 from 824 leaves us with 41.
Grab the next digit (3) from the dividend, add it to 41, then carry on: 413 / 87

Step 5:
When dividing 413 by 87, we get 4 with a remainder of 65.
The number 4 becomes the next digit in our result. 
Result so far: 594.0
The remainder is 65 after subtracting 348 from 413.
Fetch the next digit (7) from the dividend, attach it to 65 and continue: 657 / 87

Going ahead to step 6:
87 can be fit into 657 7 times, resulting in a remainder of 48.
Record the quotient 7 as the next digit in the result. 
Result so far: 5947.0
If we subtract 609 from 657, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 7:
87 goes into 480 5 times with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 5947.5
The remainder is 45 after subtracting 435 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 8:
When dividing 450 by 87, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 5947.55
Subtract 435 from 450 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 5947.55 with a remaining 0.015.
