When dividing 575 by 639, we get 0 with a remainder of 575.
The next digit of our result is 0. 
Result so far: 1350.0
The remainder is 575 after subtracting 0 from 575.
Fetch the next digit (6) from the dividend, attach it to 575 and continue: 5756 / 639

Advancing to step 7:
639 can be fit into 5756 9 times, resulting in a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 13509.0
Deduct 5751 from 5756 and we're left with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 639

Moving on to step 8:
639 goes into 50 0 times with a remainder of 50.
The next digit of our result is 0. 
Result so far: 135090.0
If we take 0 away from 50, we end up 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.

Step 9:
639 can be fit into 500 0 times, resulting in a remainder of 500.
Record the quotient 0 as the next digit in the result. 
Result so far: 135090.0
If we take 0 away from 500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Going ahead to step 10:
639 can be fit into 5000 7 times, resulting in a remainder of 527.
The number 7 becomes the next digit in our result. 
Result so far: 135090.07
Deduct 4473 from 5000 and we're left with 527.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5270, and continue the process.

On to step 11:
If we divide 5270 by 639, we get 8 and a remainder of 158.
Write down 8 as next digit of the result. 
Result so far: 135090.078
Deduct 5112 from 5270 and we're left with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Moving on to step 12:
639 can be fit into 1580 2 times, resulting in a remainder of 302.
The next digit of our result is 2. 
Result so far: 135090.0782
Deduct 1278 from 1580 and we're left with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Let's proceed to step 13:
If we divide 3020 by 639, we get 4 and a remainder of 464.
The number 4 becomes the next digit in our result. 
Result so far: 135090.07824
Deduct 2556 from 3020 and we're left with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Advancing to step 14:
4640 divided by 639 is 7 with a remainder of 167.
The number 7 becomes the next digit in our result. 
Result so far: 135090.078247
The remainder is 167 after subtracting 4473 from 4640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Step 15:
1670 divided by 639 is 2 with a remainder of 392.
Record the quotient 2 as the next digit in the result. 
Result so far: 135090.0782472
Subtract 1278 from 1670 to get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Moving on to step 16:
The number 639 fits into 3920 6 times, leaving a remainder of 86.
Put 6 as the next digit of the answer. 
Result so far: 135090.07824726
Subtracting 3834 from 3920 leaves us 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.

In conclusion, the division gives 135090.07824726 with a balance of 8.6e-08.
