Moving on to step 6:
159 can be fit into 1342 8 times, resulting in a remainder of 70.
Record the quotient 8 as the next digit in the result. 
Result so far: 5258.0
If we subtract 1272 from 1342, we get 70.
Include the next digit (5) from the dividend after 70, then repeat: 705 / 159

Moving on to step 7:
If we divide 705 by 159, we get 4 and a remainder of 69.
Record the quotient 4 as the next digit in the result. 
Result so far: 52584.0
Subtract 636 from 705 to get 69.
Include the next digit (3) from the dividend after 69, then repeat: 693 / 159

On to step 8:
When dividing 693 by 159, we get 4 with a remainder of 57.
Put 4 as the next digit of the answer. 
Result so far: 525844.0
The remainder is 57 after subtracting 636 from 693.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 9:
If we divide 570 by 159, we get 3 and a remainder of 93.
Put 3 as the next digit of the answer. 
Result so far: 525844.3
The remainder is 93 after subtracting 477 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Going ahead to step 10:
When dividing 930 by 159, we get 5 with a remainder of 135.
The next digit of our result is 5. 
Result so far: 525844.35
Deduct 795 from 930 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 11:
1350 divided by 159 is 8 with a remainder of 78.
The next digit of our result is 8. 
Result so far: 525844.358
Subtract 1272 from 1350 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 12:
159 can be fit into 780 4 times, resulting in a remainder of 144.
Write down 4 as next digit of the result. 
Result so far: 525844.3584
Subtracting 636 from 780 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 13:
If we divide 1440 by 159, we get 9 and a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 525844.35849
If we subtract 1431 from 1440, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 14:
If we divide 90 by 159, we get 0 and a remainder of 90.
The next digit of our result is 0. 
Result so far: 525844.35849
The remainder is 90 after subtracting 0 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 15:
The number 159 fits into 900 5 times, leaving a remainder of 105.
The next digit of our result is 5. 
Result so far: 525844.3584905
Subtracting 795 from 900 leaves us with 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 16:
1050 divided by 159 is 6 with a remainder of 96.
The number 6 becomes the next digit in our result. 
Result so far: 525844.35849056
The remainder is 96 after subtracting 954 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Our division results in 525844.35849056 with a remaining 9.6e-08.
