Step 4:
When dividing 587 by 312, we get 1 with a remainder of 275.
Write down 1 as next digit of the result. 
Result so far: 21.0
The remainder is 275 after subtracting 312 from 587.
Take the next digit (4) from the dividend and append it to 275, then repeat: 2754 / 312

Advancing to step 5:
312 goes into 2754 8 times with a remainder of 258.
Use 8 as the next digit of our solution. 
Result so far: 218.0
Subtract 2496 from 2754 to get 258.
Fetch the next digit (3) from the dividend, attach it to 258 and continue: 2583 / 312

Advancing to step 6:
2583 divided by 312 is 8 with a remainder of 87.
Record the quotient 8 as the next digit in the result. 
Result so far: 2188.0
Deduct 2496 from 2583 and we're left with 87.
Grab the next digit (9) from the dividend, add it to 87, then carry on: 879 / 312

Going ahead to step 7:
312 can be fit into 879 2 times, resulting in a remainder of 255.
Write down 2 as next digit of the result. 
Result so far: 21882.0
If we subtract 624 from 879, we get 255.
Grab the next digit (0) from the dividend, add it to 255, then carry on: 2550 / 312

Advancing to step 8:
312 can be fit into 2550 8 times, resulting in a remainder of 54.
Use 8 as the next digit of our solution. 
Result so far: 218828.0
If we subtract 2496 from 2550, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 9:
540 divided by 312 is 1 with a remainder of 228.
The number 1 becomes the next digit in our result. 
Result so far: 218828.1
The remainder is 228 after subtracting 312 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 10:
2280 divided by 312 is 7 with a remainder of 96.
Use 7 as the next digit of our solution. 
Result so far: 218828.17
Subtract 2184 from 2280 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 11:
312 can be fit into 960 3 times, resulting in a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 218828.173
Subtract 936 from 960 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 12:
312 can be fit into 240 0 times, resulting in a remainder of 240.
Put 0 as the next digit of the answer. 
Result so far: 218828.173
If we subtract 0 from 240, 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.

Let's proceed to step 13:
The number 312 fits into 2400 7 times, leaving a remainder of 216.
The number 7 becomes the next digit in our result. 
Result so far: 218828.17307
Subtracting 2184 from 2400 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 14:
When dividing 2160 by 312, we get 6 with a remainder of 288.
Use 6 as the next digit of our solution. 
Result so far: 218828.173076
Subtract 1872 from 2160 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

On to step 15:
312 can be fit into 2880 9 times, resulting in a remainder of 72.
Record the quotient 9 as the next digit in the result. 
Result so far: 218828.1730769
Subtract 2808 from 2880 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 16:
If we divide 720 by 312, we get 2 and a remainder of 96.
Use 2 as the next digit of our solution. 
Result so far: 218828.17307692
Subtract 624 from 720 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

The final outcome is 218828.17307692, with a leftover of 9.6e-08.
