Let's proceed to step 4:
92 divided by 143 is 0 with a remainder of 92.
Record the quotient 0 as the next digit in the result. 
Result so far: 60.0
Subtracting 0 from 92 leaves us with 92.
Fetch the next digit (4) from the dividend, attach it to 92 and continue: 924 / 143

Let's proceed to step 5:
924 divided by 143 is 6 with a remainder of 66.
Write down 6 as next digit of the result. 
Result so far: 606.0
The remainder is 66 after subtracting 858 from 924.
Fetch the next digit (3) from the dividend, attach it to 66 and continue: 663 / 143

Advancing to step 6:
If we divide 663 by 143, we get 4 and a remainder of 91.
Write down 4 as next digit of the result. 
Result so far: 6064.0
Subtract 572 from 663 to get 91.
Append the next digit (1) from the dividend to 91 and continue with: 911 / 143

Going ahead to step 7:
When dividing 911 by 143, we get 6 with a remainder of 53.
Record the quotient 6 as the next digit in the result. 
Result so far: 60646.0
The remainder is 53 after subtracting 858 from 911.
Fetch the next digit (4) from the dividend, attach it to 53 and continue: 534 / 143

Going ahead to step 8:
When dividing 534 by 143, we get 3 with a remainder of 105.
Write down 3 as next digit of the result. 
Result so far: 606463.0
The remainder is 105 after subtracting 429 from 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 9:
If we divide 1050 by 143, we get 7 and a remainder of 49.
The next digit of our result is 7. 
Result so far: 606463.7
Deduct 1001 from 1050 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 10:
When dividing 490 by 143, we get 3 with a remainder of 61.
The number 3 becomes the next digit in our result. 
Result so far: 606463.73
Subtracting 429 from 490 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 11:
If we divide 610 by 143, we get 4 and a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 606463.734
Subtract 572 from 610 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 12:
380 divided by 143 is 2 with a remainder of 94.
Record the quotient 2 as the next digit in the result. 
Result so far: 606463.7342
Subtracting 286 from 380 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 13:
If we divide 940 by 143, we get 6 and a remainder of 82.
The number 6 becomes the next digit in our result. 
Result so far: 606463.73426
Subtracting 858 from 940 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 14:
143 goes into 820 5 times with a remainder of 105.
Write down 5 as next digit of the result. 
Result so far: 606463.734265
If we subtract 715 from 820, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 15:
143 can be fit into 1050 7 times, resulting in a remainder of 49.
The number 7 becomes the next digit in our result. 
Result so far: 606463.7342657
Deduct 1001 from 1050 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 16:
143 goes into 490 3 times with a remainder of 61.
Use 3 as the next digit of our solution. 
Result so far: 606463.73426573
If we subtract 429 from 490, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

The final result is 606463.73426573 with a remainder of 6.1e-08.
