The number 575 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 575

Advancing to step 2:
If we divide 39 by 575, we get 0 and a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 575

Moving on to step 3:
If we divide 399 by 575, we get 0 and a remainder of 399.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 399, we end up with 399.
Fetch the next digit (7) from the dividend, attach it to 399 and continue: 3997 / 575

On to step 4:
575 can be fit into 3997 6 times, resulting in a remainder of 547.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 3450 from 3997, we get 547.
Grab the next digit (8) from the dividend, add it to 547, then carry on: 5478 / 575

On to step 5:
5478 divided by 575 is 9 with a remainder of 303.
The next digit of our result is 9. 
Result so far: 69.0
Subtract 5175 from 5478 to get 303.
Grab the next digit (4) from the dividend, add it to 303, then carry on: 3034 / 575

Going ahead to step 6:
575 goes into 3034 5 times with a remainder of 159.
Use 5 as the next digit of our solution. 
Result so far: 695.0
Deduct 2875 from 3034 and we're left with 159.
Fetch the next digit (4) from the dividend, attach it to 159 and continue: 1594 / 575

Advancing to step 7:
575 goes into 1594 2 times with a remainder of 444.
The next digit of our result is 2. 
Result so far: 6952.0
Subtracting 1150 from 1594 leaves us with 444.
Append the next digit (2) from the dividend to 444 and continue with: 4442 / 575

Step 8:
When dividing 4442 by 575, we get 7 with a remainder of 417.
The next digit of our result is 7. 
Result so far: 69527.0
Deduct 4025 from 4442 and we're left with 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

On to step 9:
575 can be fit into 4170 7 times, resulting in a remainder of 145.
Use 7 as the next digit of our solution. 
Result so far: 69527.7
If we take 4025 away from 4170, we end up with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Advancing to step 10:
575 goes into 1450 2 times with a remainder of 300.
Use 2 as the next digit of our solution. 
Result so far: 69527.72
Subtracting 1150 from 1450 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 11:
575 goes into 3000 5 times with a remainder of 125.
The number 5 becomes the next digit in our result. 
Result so far: 69527.725
Subtract 2875 from 3000 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 12:
If we divide 1250 by 575, we get 2 and a remainder of 100.
Write down 2 as next digit of the result. 
Result so far: 69527.7252
Subtracting 1150 from 1250 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 13:
If we divide 1000 by 575, we get 1 and a remainder of 425.
The next digit of our result is 1. 
Result so far: 69527.72521
The remainder is 425 after subtracting 575 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Advancing to step 14:
If we divide 4250 by 575, we get 7 and a remainder of 225.
Use 7 as the next digit of our solution. 
Result so far: 69527.725217
Subtracting 4025 from 4250 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Moving on to step 15:
When dividing 2250 by 575, we get 3 with a remainder of 525.
The next digit of our result is 3. 
Result so far: 69527.7252173
The remainder is 525 after subtracting 1725 from 2250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

On to step 16:
The number 575 fits into 5250 9 times, leaving a remainder of 75.
The next digit of our result is 9. 
Result so far: 69527.72521739
Subtracting 5175 from 5250 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Our division results in 69527.72521739 with a remaining 7.5e-08.
