The number 530 fits into 5287 9 times, leaving a remainder of 517.
The number 9 becomes the next digit in our result. 
Result so far: 129.0
Subtract 4770 from 5287 to get 517.
Include the next digit (0) from the dividend after 517, then repeat: 5170 / 530

Step 6:
530 can be fit into 5170 9 times, resulting in a remainder of 400.
The number 9 becomes the next digit in our result. 
Result so far: 1299.0
Subtracting 4770 from 5170 leaves us with 400.
Append the next digit (9) from the dividend to 400 and continue with: 4009 / 530

Moving on to step 7:
The number 530 fits into 4009 7 times, leaving a remainder of 299.
Record the quotient 7 as the next digit in the result. 
Result so far: 12997.0
If we take 3710 away from 4009, we end up with 299.
Include the next digit (0) from the dividend after 299, then repeat: 2990 / 530

Let's proceed to step 8:
The number 530 fits into 2990 5 times, leaving a remainder of 340.
The number 5 becomes the next digit in our result. 
Result so far: 129975.0
Subtract 2650 from 2990 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 9:
530 can be fit into 3400 6 times, resulting in a remainder of 220.
The next digit of our result is 6. 
Result so far: 129975.6
Subtracting 3180 from 3400 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 10:
2200 divided by 530 is 4 with a remainder of 80.
The next digit of our result is 4. 
Result so far: 129975.64
If we subtract 2120 from 2200, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 11:
When dividing 800 by 530, we get 1 with a remainder of 270.
The number 1 becomes the next digit in our result. 
Result so far: 129975.641
The remainder is 270 after subtracting 530 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 12:
The number 530 fits into 2700 5 times, leaving a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 129975.6415
Subtracting 2650 from 2700 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 13:
500 divided by 530 is 0 with a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 129975.6415
Subtract 0 from 500 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

On to step 14:
The number 530 fits into 5000 9 times, leaving a remainder of 230.
Record the quotient 9 as the next digit in the result. 
Result so far: 129975.641509
Subtract 4770 from 5000 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 15:
2300 divided by 530 is 4 with a remainder of 180.
The number 4 becomes the next digit in our result. 
Result so far: 129975.6415094
If we subtract 2120 from 2300, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 16:
If we divide 1800 by 530, we get 3 and a remainder of 210.
The next digit of our result is 3. 
Result so far: 129975.64150943
Deduct 1590 from 1800 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

The final outcome is 129975.64150943, with a leftover of 2.1e-07.
