We look at the division of 520862 by 87 
We want to figure out the number of times 520862 can be divided by 87.

On to step 1:
5 divided by 87 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 87

Moving on to step 2:
87 goes into 52 0 times with a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 52 leaves us with 52.
Include the next digit (0) from the dividend after 52, then repeat: 520 / 87

Let's proceed to step 3:
87 can be fit into 520 5 times, resulting in a remainder of 85.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 435 from 520, we get 85.
Append the next digit (8) from the dividend to 85 and continue with: 858 / 87

On to step 4:
When dividing 858 by 87, we get 9 with a remainder of 75.
The next digit of our result is 9. 
Result so far: 59.0
If we take 783 away from 858, we end up with 75.
Bring next digit (6) of the dividend behind the 75 and repeat the process: 756 / 87

Step 5:
87 can be fit into 756 8 times, resulting in a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 598.0
Deduct 696 from 756 and we're left with 60.
Include the next digit (2) from the dividend after 60, then repeat: 602 / 87

Step 6:
The number 87 fits into 602 6 times, leaving a remainder of 80.
Write down 6 as next digit of the result. 
Result so far: 5986.0
The remainder is 80 after subtracting 522 from 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 7:
87 can be fit into 800 9 times, resulting in a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 5986.9
Deduct 783 from 800 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 8:
The number 87 fits into 170 1 times, leaving a remainder of 83.
The number 1 becomes the next digit in our result. 
Result so far: 5986.91
If we take 87 away from 170, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 9:
87 goes into 830 9 times with a remainder of 47.
Record the quotient 9 as the next digit in the result. 
Result so far: 5986.919
If we take 783 away from 830, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 10:
The number 87 fits into 470 5 times, leaving a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 5986.9195
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.

Going ahead to step 11:
If we divide 350 by 87, we get 4 and a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 5986.91954
If we subtract 348 from 350, we 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.

Step 12:
The number 87 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 5986.91954
If we take 0 away from 20, we end up 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.

On to step 13:
87 goes into 200 2 times with a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 5986.9195402
If we take 174 away from 200, we end up 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.

Going ahead to step 14:
When dividing 260 by 87, we get 2 with a remainder of 86.
Use 2 as the next digit of our solution. 
Result so far: 5986.91954022
If we take 174 away from 260, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The quotient of the division is 5986.91954022, and the remainder is 8.6e-08.
