510647 ÷ 87 
Let's see how many times 87 fits into 510647.

Going ahead to step 1:
87 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 87

Going ahead to step 2:
87 goes into 51 0 times with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Grab the next digit (0) from the dividend, add it to 51, then carry on: 510 / 87

Let's proceed to step 3:
87 goes into 510 5 times with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 75 after subtracting 435 from 510.
Grab the next digit (6) from the dividend, add it to 75, then carry on: 756 / 87

Step 4:
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: 58.0
Subtract 696 from 756 to get 60.
Include the next digit (4) from the dividend after 60, then repeat: 604 / 87

Advancing to step 5:
When dividing 604 by 87, we get 6 with a remainder of 82.
The number 6 becomes the next digit in our result. 
Result so far: 586.0
If we subtract 522 from 604, we get 82.
Fetch the next digit (7) from the dividend, attach it to 82 and continue: 827 / 87

Let's proceed to step 6:
The number 87 fits into 827 9 times, leaving a remainder of 44.
The next digit of our result is 9. 
Result so far: 5869.0
Deduct 783 from 827 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 7:
When dividing 440 by 87, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 5869.5
Subtract 435 from 440 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
87 goes into 50 0 times with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 5869.5
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
500 divided by 87 is 5 with a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 5869.505
If we take 435 away from 500, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 10:
The number 87 fits into 650 7 times, leaving a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 5869.5057
If we subtract 609 from 650, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 11:
If we divide 410 by 87, we get 4 and a remainder of 62.
The number 4 becomes the next digit in our result. 
Result so far: 5869.50574
If we subtract 348 from 410, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 12:
620 divided by 87 is 7 with a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 5869.505747
Subtract 609 from 620 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 13:
When dividing 110 by 87, we get 1 with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 5869.5057471
The remainder is 23 after subtracting 87 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 14:
The number 87 fits into 230 2 times, leaving a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 5869.50574712
If we subtract 174 from 230, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final result is 5869.50574712 with a remainder of 5.6e-08.
