87287047 ÷ 312 
We want to divide 87287047 by 312.

Advancing to step 1:
If we divide 8 by 312, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 312

Let's proceed to step 2:
312 goes into 87 0 times with a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Include the next digit (2) from the dividend after 87, then repeat: 872 / 312

Moving on to step 3:
312 can be fit into 872 2 times, resulting in a remainder of 248.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 624 from 872 to get 248.
Fetch the next digit (8) from the dividend, attach it to 248 and continue: 2488 / 312

Going ahead to step 4:
The number 312 fits into 2488 7 times, leaving a remainder of 304.
Use 7 as the next digit of our solution. 
Result so far: 27.0
Deduct 2184 from 2488 and we're left with 304.
Fetch the next digit (7) from the dividend, attach it to 304 and continue: 3047 / 312

Let's proceed to step 5:
The number 312 fits into 3047 9 times, leaving a remainder of 239.
Write down 9 as next digit of the result. 
Result so far: 279.0
If we take 2808 away from 3047, we end up with 239.
Include the next digit (0) from the dividend after 239, then repeat: 2390 / 312

Going ahead to step 6:
The number 312 fits into 2390 7 times, leaving a remainder of 206.
The number 7 becomes the next digit in our result. 
Result so far: 2797.0
If we take 2184 away from 2390, we end up with 206.
Fetch the next digit (4) from the dividend, attach it to 206 and continue: 2064 / 312

Let's proceed to step 7:
If we divide 2064 by 312, we get 6 and a remainder of 192.
The next digit of our result is 6. 
Result so far: 27976.0
Deduct 1872 from 2064 and we're left with 192.
Take the next digit (7) from the dividend and append it to 192, then repeat: 1927 / 312

Let's proceed to step 8:
When dividing 1927 by 312, we get 6 with a remainder of 55.
The next digit of our result is 6. 
Result so far: 279766.0
If we subtract 1872 from 1927, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 9:
550 divided by 312 is 1 with a remainder of 238.
Put 1 as the next digit of the answer. 
Result so far: 279766.1
If we subtract 312 from 550, we get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

On to step 10:
When dividing 2380 by 312, we get 7 with a remainder of 196.
Write down 7 as next digit of the result. 
Result so far: 279766.17
If we subtract 2184 from 2380, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Going ahead to step 11:
312 goes into 1960 6 times with a remainder of 88.
Put 6 as the next digit of the answer. 
Result so far: 279766.176
If we take 1872 away from 1960, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 12:
312 can be fit into 880 2 times, resulting in a remainder of 256.
Write down 2 as next digit of the result. 
Result so far: 279766.1762
Deduct 624 from 880 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 13:
312 can be fit into 2560 8 times, resulting in a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 279766.17628
If we take 2496 away from 2560, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 14:
If we divide 640 by 312, we get 2 and a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 279766.176282
If we subtract 624 from 640, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 15:
If we divide 160 by 312, we get 0 and a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 279766.176282
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 16:
The number 312 fits into 1600 5 times, leaving a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 279766.17628205
The remainder is 40 after subtracting 1560 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 279766.17628205 and a remainder of 4e-08.
