8670749 divided by 287 
We want to divide 8670749 by 287.

On to step 1:
8 divided by 287 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 287

Moving on to step 2:
If we divide 86 by 287, we get 0 and a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Include the next digit (7) from the dividend after 86, then repeat: 867 / 287

Advancing to step 3:
When dividing 867 by 287, we get 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 6 after subtracting 861 from 867.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 287

Advancing to step 4:
60 divided by 287 is 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 30.0
Subtracting 0 from 60 leaves us with 60.
Include the next digit (7) from the dividend after 60, then repeat: 607 / 287

Step 5:
The number 287 fits into 607 2 times, leaving a remainder of 33.
Record the quotient 2 as the next digit in the result. 
Result so far: 302.0
Subtracting 574 from 607 leaves us with 33.
Fetch the next digit (4) from the dividend, attach it to 33 and continue: 334 / 287

Let's proceed to step 6:
When dividing 334 by 287, we get 1 with a remainder of 47.
The number 1 becomes the next digit in our result. 
Result so far: 3021.0
Deduct 287 from 334 and we're left with 47.
Take the next digit (9) from the dividend and append it to 47, then repeat: 479 / 287

On to step 7:
When dividing 479 by 287, we get 1 with a remainder of 192.
Put 1 as the next digit of the answer. 
Result so far: 30211.0
If we subtract 287 from 479, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 8:
If we divide 1920 by 287, we get 6 and a remainder of 198.
The next digit of our result is 6. 
Result so far: 30211.6
Deduct 1722 from 1920 and we're left with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

On to step 9:
The number 287 fits into 1980 6 times, leaving a remainder of 258.
The next digit of our result is 6. 
Result so far: 30211.66
If we subtract 1722 from 1980, we get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

After the division, we end up with 30211.66 and a remainder of 0.258.
