We look at the division of 15720499 by 580 
We want to divide 15720499 by 580.

On to step 1:
If we divide 1 by 580, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 580

Step 2:
The number 580 fits into 15 0 times, leaving a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Include the next digit (7) from the dividend after 15, then repeat: 157 / 580

On to step 3:
157 divided by 580 is 0 with a remainder of 157.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 157, we end up with 157.
Grab the next digit (2) from the dividend, add it to 157, then carry on: 1572 / 580

Step 4:
580 goes into 1572 2 times with a remainder of 412.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1160 from 1572 to get 412.
Bring next digit (0) of the dividend behind the 412 and repeat the process: 4120 / 580

Step 5:
580 can be fit into 4120 7 times, resulting in a remainder of 60.
Use 7 as the next digit of our solution. 
Result so far: 27.0
If we subtract 4060 from 4120, we get 60.
Fetch the next digit (4) from the dividend, attach it to 60 and continue: 604 / 580

On to step 6:
If we divide 604 by 580, we get 1 and a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 271.0
If we subtract 580 from 604, we get 24.
Fetch the next digit (9) from the dividend, attach it to 24 and continue: 249 / 580

Advancing to step 7:
580 can be fit into 249 0 times, resulting in a remainder of 249.
The number 0 becomes the next digit in our result. 
Result so far: 2710.0
Deduct 0 from 249 and we're left with 249.
Take the next digit (9) from the dividend and append it to 249, then repeat: 2499 / 580

Let's proceed to step 8:
If we divide 2499 by 580, we get 4 and a remainder of 179.
Write down 4 as next digit of the result. 
Result so far: 27104.0
If we subtract 2320 from 2499, we get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

On to step 9:
The number 580 fits into 1790 3 times, leaving a remainder of 50.
Put 3 as the next digit of the answer. 
Result so far: 27104.3
Subtract 1740 from 1790 to get 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 10:
The number 580 fits into 500 0 times, leaving a remainder of 500.
Record the quotient 0 as the next digit in the result. 
Result so far: 27104.3
Deduct 0 from 500 and we're left 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.

Let's proceed to step 11:
If we divide 5000 by 580, we get 8 and a remainder of 360.
The number 8 becomes the next digit in our result. 
Result so far: 27104.308
Subtracting 4640 from 5000 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 12:
If we divide 3600 by 580, we get 6 and a remainder of 120.
Put 6 as the next digit of the answer. 
Result so far: 27104.3086
Subtracting 3480 from 3600 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.

Step 13:
The number 580 fits into 1200 2 times, leaving a remainder of 40.
The next digit of our result is 2. 
Result so far: 27104.30862
The remainder is 40 after subtracting 1160 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 14:
580 can be fit into 400 0 times, resulting in a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 27104.30862
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 15:
580 goes into 4000 6 times with a remainder of 520.
The number 6 becomes the next digit in our result. 
Result so far: 27104.3086206
The remainder is 520 after subtracting 3480 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Advancing to step 16:
If we divide 5200 by 580, we get 8 and a remainder of 560.
Write down 8 as next digit of the result. 
Result so far: 27104.30862068
Subtracting 4640 from 5200 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

After the division, we end up with 27104.30862068 and a remainder of 5.6e-07.
