Advancing to step 6:
143 goes into 57 0 times with a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 6140.0
Subtract 0 from 57 to get 57.
Take the next digit (7) from the dividend and append it to 57, then repeat: 577 / 143

Advancing to step 7:
143 can be fit into 577 4 times, resulting in a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 61404.0
The remainder is 5 after subtracting 572 from 577.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 143

Step 8:
The number 143 fits into 57 0 times, leaving a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 614040.0
Subtracting 0 from 57 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 9:
570 divided by 143 is 3 with a remainder of 141.
Write down 3 as next digit of the result. 
Result so far: 614040.3
Subtracting 429 from 570 leaves us with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Advancing to step 10:
143 goes into 1410 9 times with a remainder of 123.
Use 9 as the next digit of our solution. 
Result so far: 614040.39
The remainder is 123 after subtracting 1287 from 1410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

On to step 11:
When dividing 1230 by 143, we get 8 with a remainder of 86.
Use 8 as the next digit of our solution. 
Result so far: 614040.398
If we take 1144 away from 1230, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 12:
The number 143 fits into 860 6 times, leaving a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 614040.3986
Deduct 858 from 860 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 13:
143 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 614040.3986
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 14:
If we divide 200 by 143, we get 1 and a remainder of 57.
Use 1 as the next digit of our solution. 
Result so far: 614040.398601
If we take 143 away from 200, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 15:
143 can be fit into 570 3 times, resulting in a remainder of 141.
Put 3 as the next digit of the answer. 
Result so far: 614040.3986013
If we take 429 away from 570, we end up with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Let's proceed to step 16:
When dividing 1410 by 143, we get 9 with a remainder of 123.
The number 9 becomes the next digit in our result. 
Result so far: 614040.39860139
The remainder is 123 after subtracting 1287 from 1410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

The final result is 614040.39860139 with a remainder of 1.23e-07.
