520360 ÷ 87 
We want to figure out the number of times 520360 can be divided by 87.

On to step 1:
87 goes into 5 0 times 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.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 87

Step 2:
87 can be fit into 52 0 times, resulting in a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 52 after subtracting 0 from 52.
Fetch the next digit (0) from the dividend, attach it to 52 and continue: 520 / 87

Going ahead to step 3:
If we divide 520 by 87, we get 5 and a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 435 from 520 to get 85.
Bring next digit (3) of the dividend behind the 85 and repeat the process: 853 / 87

Going ahead to step 4:
853 divided by 87 is 9 with a remainder of 70.
Write down 9 as next digit of the result. 
Result so far: 59.0
Subtracting 783 from 853 leaves us with 70.
Fetch the next digit (6) from the dividend, attach it to 70 and continue: 706 / 87

Advancing to step 5:
When dividing 706 by 87, we get 8 with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 598.0
Subtract 696 from 706 to get 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 87

Step 6:
The number 87 fits into 100 1 times, leaving a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 5981.0
Deduct 87 from 100 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
87 can be fit into 130 1 times, resulting in a remainder of 43.
The number 1 becomes the next digit in our result. 
Result so far: 5981.1
Subtract 87 from 130 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 8:
87 goes into 430 4 times with a remainder of 82.
Use 4 as the next digit of our solution. 
Result so far: 5981.14
The remainder is 82 after subtracting 348 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 9:
87 goes into 820 9 times with a remainder of 37.
The next digit of our result is 9. 
Result so far: 5981.149
The remainder is 37 after subtracting 783 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 10:
87 can be fit into 370 4 times, resulting in a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 5981.1494
Subtracting 348 from 370 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 11:
When dividing 220 by 87, we get 2 with a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 5981.14942
If we subtract 174 from 220, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 12:
87 goes into 460 5 times with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 5981.149425
If we take 435 away from 460, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 13:
87 goes into 250 2 times with a remainder of 76.
Record the quotient 2 as the next digit in the result. 
Result so far: 5981.1494252
If we subtract 174 from 250, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 14:
When dividing 760 by 87, we get 8 with a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 5981.14942528
The remainder is 64 after subtracting 696 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 5981.14942528 with a remaining 6.4e-08.
