We look at the division of 28861515 by 312 
We're looking to find how many times 312 goes into 28861515.

Moving on to step 1:
The number 312 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 312

Step 2:
The number 312 fits into 28 0 times, leaving a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Append the next digit (8) from the dividend to 28 and continue with: 288 / 312

Let's proceed to step 3:
When dividing 288 by 312, we get 0 with a remainder of 288.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 288 and we're left with 288.
Bring next digit (6) of the dividend behind the 288 and repeat the process: 2886 / 312

Going ahead to step 4:
312 can be fit into 2886 9 times, resulting in a remainder of 78.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 2808 from 2886, we get 78.
Fetch the next digit (1) from the dividend, attach it to 78 and continue: 781 / 312

Advancing to step 5:
781 divided by 312 is 2 with a remainder of 157.
Record the quotient 2 as the next digit in the result. 
Result so far: 92.0
Subtracting 624 from 781 leaves us with 157.
Take the next digit (5) from the dividend and append it to 157, then repeat: 1575 / 312

Step 6:
312 goes into 1575 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 925.0
Subtract 1560 from 1575 to get 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 312

Moving on to step 7:
If we divide 151 by 312, we get 0 and a remainder of 151.
Record the quotient 0 as the next digit in the result. 
Result so far: 9250.0
Subtracting 0 from 151 leaves us with 151.
Grab the next digit (5) from the dividend, add it to 151, then carry on: 1515 / 312

On to step 8:
1515 divided by 312 is 4 with a remainder of 267.
The next digit of our result is 4. 
Result so far: 92504.0
If we take 1248 away from 1515, we end up with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Step 9:
If we divide 2670 by 312, we get 8 and a remainder of 174.
Record the quotient 8 as the next digit in the result. 
Result so far: 92504.8
The remainder is 174 after subtracting 2496 from 2670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Step 10:
When dividing 1740 by 312, we get 5 with a remainder of 180.
Write down 5 as next digit of the result. 
Result so far: 92504.85
Deduct 1560 from 1740 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 11:
1800 divided by 312 is 5 with a remainder of 240.
Use 5 as the next digit of our solution. 
Result so far: 92504.855
If we subtract 1560 from 1800, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The final outcome is 92504.855, with a leftover of 0.024.
