87861314 ÷ 510 
We want to figure out the number of times 87861314 can be divided by 510.

Advancing to step 1:
If we divide 8 by 510, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 510

Moving on to step 2:
When dividing 87 by 510, we get 0 with a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Take the next digit (8) from the dividend and append it to 87, then repeat: 878 / 510

Moving on to step 3:
878 divided by 510 is 1 with a remainder of 368.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 368 after subtracting 510 from 878.
Bring next digit (6) of the dividend behind the 368 and repeat the process: 3686 / 510

Going ahead to step 4:
3686 divided by 510 is 7 with a remainder of 116.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtract 3570 from 3686 to get 116.
Take the next digit (1) from the dividend and append it to 116, then repeat: 1161 / 510

On to step 5:
510 can be fit into 1161 2 times, resulting in a remainder of 141.
Put 2 as the next digit of the answer. 
Result so far: 172.0
Deduct 1020 from 1161 and we're left with 141.
Grab the next digit (3) from the dividend, add it to 141, then carry on: 1413 / 510

Going ahead to step 6:
When dividing 1413 by 510, we get 2 with a remainder of 393.
The next digit of our result is 2. 
Result so far: 1722.0
Subtract 1020 from 1413 to get 393.
Fetch the next digit (1) from the dividend, attach it to 393 and continue: 3931 / 510

Advancing to step 7:
When dividing 3931 by 510, we get 7 with a remainder of 361.
Write down 7 as next digit of the result. 
Result so far: 17227.0
The remainder is 361 after subtracting 3570 from 3931.
Fetch the next digit (4) from the dividend, attach it to 361 and continue: 3614 / 510

Moving on to step 8:
The number 510 fits into 3614 7 times, leaving a remainder of 44.
The next digit of our result is 7. 
Result so far: 172277.0
If we take 3570 away from 3614, we end up 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 9:
The number 510 fits into 440 0 times, leaving a remainder of 440.
The number 0 becomes the next digit in our result. 
Result so far: 172277.0
Subtract 0 from 440 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Let's proceed to step 10:
510 goes into 4400 8 times with a remainder of 320.
Write down 8 as next digit of the result. 
Result so far: 172277.08
Deduct 4080 from 4400 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 11:
When dividing 3200 by 510, we get 6 with a remainder of 140.
The number 6 becomes the next digit in our result. 
Result so far: 172277.086
Subtracting 3060 from 3200 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 12:
510 goes into 1400 2 times with a remainder of 380.
Use 2 as the next digit of our solution. 
Result so far: 172277.0862
Deduct 1020 from 1400 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 13:
3800 divided by 510 is 7 with a remainder of 230.
Use 7 as the next digit of our solution. 
Result so far: 172277.08627
If we subtract 3570 from 3800, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 14:
When dividing 2300 by 510, we get 4 with a remainder of 260.
Record the quotient 4 as the next digit in the result. 
Result so far: 172277.086274
Subtracting 2040 from 2300 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 15:
When dividing 2600 by 510, we get 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 172277.0862745
Deduct 2550 from 2600 and we're left 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.

Let's proceed to step 16:
500 divided by 510 is 0 with a remainder of 500.
Record the quotient 0 as the next digit in the result. 
Result so far: 172277.0862745
Subtract 0 from 500 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The final result is 172277.0862745 with a remainder of 5e-07.
