We're dividing 452099 by 87 
Let's see how many times 87 fits into 452099.

On to step 1:
87 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 87

Going ahead to step 2:
If we divide 45 by 87, we get 0 and a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Take the next digit (2) from the dividend and append it to 45, then repeat: 452 / 87

On to step 3:
87 goes into 452 5 times with a remainder of 17.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 435 from 452, we get 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 87

Step 4:
87 goes into 170 1 times with a remainder of 83.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
Deduct 87 from 170 and we're left with 83.
Bring next digit (9) of the dividend behind the 83 and repeat the process: 839 / 87

Going ahead to step 5:
87 goes into 839 9 times with a remainder of 56.
Record the quotient 9 as the next digit in the result. 
Result so far: 519.0
Subtracting 783 from 839 leaves us with 56.
Include the next digit (9) from the dividend after 56, then repeat: 569 / 87

Step 6:
569 divided by 87 is 6 with a remainder of 47.
The next digit of our result is 6. 
Result so far: 5196.0
Deduct 522 from 569 and we're left 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.

Advancing to step 7:
When dividing 470 by 87, we get 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 5196.5
Subtract 435 from 470 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 8:
If we divide 350 by 87, we get 4 and a remainder of 2.
The next digit of our result is 4. 
Result so far: 5196.54
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.

Let's proceed to step 9:
If we divide 20 by 87, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 5196.54
The remainder is 20 after subtracting 0 from 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 10:
200 divided by 87 is 2 with a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 5196.5402
The remainder is 26 after subtracting 174 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 11:
When dividing 260 by 87, we get 2 with a remainder of 86.
Record the quotient 2 as the next digit in the result. 
Result so far: 5196.54022
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 final result is 5196.54022 with a remainder of 8.6e-05.
