Advancing to step 4:
568 goes into 3114 5 times with a remainder of 274.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 2840 away from 3114, we end up with 274.
Include the next digit (2) from the dividend after 274, then repeat: 2742 / 568

Going ahead to step 5:
568 can be fit into 2742 4 times, resulting in a remainder of 470.
Put 4 as the next digit of the answer. 
Result so far: 54.0
If we take 2272 away from 2742, we end up with 470.
Fetch the next digit (5) from the dividend, attach it to 470 and continue: 4705 / 568

Moving on to step 6:
The number 568 fits into 4705 8 times, leaving a remainder of 161.
The next digit of our result is 8. 
Result so far: 548.0
If we take 4544 away from 4705, we end up with 161.
Append the next digit (7) from the dividend to 161 and continue with: 1617 / 568

Moving on to step 7:
When dividing 1617 by 568, we get 2 with a remainder of 481.
Put 2 as the next digit of the answer. 
Result so far: 5482.0
Subtract 1136 from 1617 to get 481.
Take the next digit (8) from the dividend and append it to 481, then repeat: 4818 / 568

Going ahead to step 8:
4818 divided by 568 is 8 with a remainder of 274.
Record the quotient 8 as the next digit in the result. 
Result so far: 54828.0
Subtract 4544 from 4818 to get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Step 9:
When dividing 2740 by 568, we get 4 with a remainder of 468.
Use 4 as the next digit of our solution. 
Result so far: 54828.4
If we subtract 2272 from 2740, we get 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Step 10:
If we divide 4680 by 568, we get 8 and a remainder of 136.
Record the quotient 8 as the next digit in the result. 
Result so far: 54828.48
The remainder is 136 after subtracting 4544 from 4680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 11:
The number 568 fits into 1360 2 times, leaving a remainder of 224.
The next digit of our result is 2. 
Result so far: 54828.482
Subtracting 1136 from 1360 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Moving on to step 12:
568 can be fit into 2240 3 times, resulting in a remainder of 536.
Use 3 as the next digit of our solution. 
Result so far: 54828.4823
If we take 1704 away from 2240, we end up with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Advancing to step 13:
568 goes into 5360 9 times with a remainder of 248.
Use 9 as the next digit of our solution. 
Result so far: 54828.48239
Deduct 5112 from 5360 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Step 14:
2480 divided by 568 is 4 with a remainder of 208.
The number 4 becomes the next digit in our result. 
Result so far: 54828.482394
The remainder is 208 after subtracting 2272 from 2480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 15:
The number 568 fits into 2080 3 times, leaving a remainder of 376.
Write down 3 as next digit of the result. 
Result so far: 54828.4823943
Deduct 1704 from 2080 and we're left with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Let's proceed to step 16:
The number 568 fits into 3760 6 times, leaving a remainder of 352.
The next digit of our result is 6. 
Result so far: 54828.48239436
Subtract 3408 from 3760 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

The final outcome is 54828.48239436, with a leftover of 3.52e-07.
