Moving on to step 8:
591 goes into 4644 7 times with a remainder of 507.
The number 7 becomes the next digit in our result. 
Result so far: 148877.0
Deduct 4137 from 4644 and we're left with 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

Moving on to step 9:
When dividing 5070 by 591, we get 8 with a remainder of 342.
Record the quotient 8 as the next digit in the result. 
Result so far: 148877.8
Subtracting 4728 from 5070 leaves us with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Step 10:
When dividing 3420 by 591, we get 5 with a remainder of 465.
The next digit of our result is 5. 
Result so far: 148877.85
Subtract 2955 from 3420 to get 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Going ahead to step 11:
The number 591 fits into 4650 7 times, leaving a remainder of 513.
Use 7 as the next digit of our solution. 
Result so far: 148877.857
If we subtract 4137 from 4650, we get 513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

Advancing to step 12:
5130 divided by 591 is 8 with a remainder of 402.
Record the quotient 8 as the next digit in the result. 
Result so far: 148877.8578
Subtract 4728 from 5130 to get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

On to step 13:
If we divide 4020 by 591, we get 6 and a remainder of 474.
Use 6 as the next digit of our solution. 
Result so far: 148877.85786
The remainder is 474 after subtracting 3546 from 4020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Going ahead to step 14:
4740 divided by 591 is 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 148877.857868
Subtracting 4728 from 4740 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 15:
120 divided by 591 is 0 with a remainder of 120.
The next digit of our result is 0. 
Result so far: 148877.857868
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 16:
If we divide 1200 by 591, we get 2 and a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 148877.85786802
Subtract 1182 from 1200 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 148877.85786802, with a leftover of 1.8e-08.
