We look at the division of 87857618 by 510 
We're looking to find how many times 510 goes into 87857618.

Let's proceed to step 1:
When dividing 8 by 510, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 510

Moving on to step 2:
510 goes into 87 0 times with a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Grab the next digit (8) from the dividend, add it to 87, then carry on: 878 / 510

Moving on to step 3:
The number 510 fits into 878 1 times, leaving a remainder of 368.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 510 from 878 and we're left with 368.
Append the next digit (5) from the dividend to 368 and continue with: 3685 / 510

Advancing to step 4:
3685 divided by 510 is 7 with a remainder of 115.
The next digit of our result is 7. 
Result so far: 17.0
If we take 3570 away from 3685, we end up with 115.
Append the next digit (7) from the dividend to 115 and continue with: 1157 / 510

Going ahead to step 5:
510 can be fit into 1157 2 times, resulting in a remainder of 137.
Put 2 as the next digit of the answer. 
Result so far: 172.0
If we subtract 1020 from 1157, we get 137.
Append the next digit (6) from the dividend to 137 and continue with: 1376 / 510

Advancing to step 6:
The number 510 fits into 1376 2 times, leaving a remainder of 356.
The next digit of our result is 2. 
Result so far: 1722.0
Deduct 1020 from 1376 and we're left with 356.
Include the next digit (1) from the dividend after 356, then repeat: 3561 / 510

Going ahead to step 7:
When dividing 3561 by 510, we get 6 with a remainder of 501.
The number 6 becomes the next digit in our result. 
Result so far: 17226.0
Subtract 3060 from 3561 to get 501.
Take the next digit (8) from the dividend and append it to 501, then repeat: 5018 / 510

On to step 8:
510 can be fit into 5018 9 times, resulting in a remainder of 428.
Write down 9 as next digit of the result. 
Result so far: 172269.0
The remainder is 428 after subtracting 4590 from 5018.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

On to step 9:
510 goes into 4280 8 times with a remainder of 200.
Put 8 as the next digit of the answer. 
Result so far: 172269.8
Subtracting 4080 from 4280 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 10:
510 can be fit into 2000 3 times, resulting in a remainder of 470.
Put 3 as the next digit of the answer. 
Result so far: 172269.83
If we subtract 1530 from 2000, we get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Moving on to step 11:
When dividing 4700 by 510, we get 9 with a remainder of 110.
The next digit of our result is 9. 
Result so far: 172269.839
Subtracting 4590 from 4700 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 12:
If we divide 1100 by 510, we get 2 and a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 172269.8392
The remainder is 80 after subtracting 1020 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 13:
800 divided by 510 is 1 with a remainder of 290.
Put 1 as the next digit of the answer. 
Result so far: 172269.83921
Deduct 510 from 800 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 14:
If we divide 2900 by 510, we get 5 and a remainder of 350.
Write down 5 as next digit of the result. 
Result so far: 172269.839215
If we take 2550 away from 2900, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Moving on to step 15:
3500 divided by 510 is 6 with a remainder of 440.
Use 6 as the next digit of our solution. 
Result so far: 172269.8392156
The remainder is 440 after subtracting 3060 from 3500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 16:
If we divide 4400 by 510, we get 8 and a remainder of 320.
Record the quotient 8 as the next digit in the result. 
Result so far: 172269.83921568
Subtract 4080 from 4400 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The final result is 172269.83921568 with a remainder of 3.2e-07.
