Let's divide 15663373 by 580
We want to divide 15663373 by 580.

Advancing to step 1:
1 divided by 580 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 580

Moving on to step 2:
15 divided by 580 is 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 580

Advancing to step 3:
580 can be fit into 156 0 times, resulting in a remainder of 156.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 156 leaves us with 156.
Bring next digit (6) of the dividend behind the 156 and repeat the process: 1566 / 580

On to step 4:
580 goes into 1566 2 times with a remainder of 406.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 1160 from 1566 leaves us with 406.
Take the next digit (3) from the dividend and append it to 406, then repeat: 4063 / 580

Step 5:
4063 divided by 580 is 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 27.0
Deduct 4060 from 4063 and we're left with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 580

Moving on to step 6:
580 can be fit into 33 0 times, resulting in a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 270.0
Subtract 0 from 33 to get 33.
Append the next digit (7) from the dividend to 33 and continue with: 337 / 580

On to step 7:
337 divided by 580 is 0 with a remainder of 337.
Use 0 as the next digit of our solution. 
Result so far: 2700.0
If we take 0 away from 337, we end up with 337.
Include the next digit (3) from the dividend after 337, then repeat: 3373 / 580

Advancing to step 8:
The number 580 fits into 3373 5 times, leaving a remainder of 473.
Put 5 as the next digit of the answer. 
Result so far: 27005.0
The remainder is 473 after subtracting 2900 from 3373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Moving on to step 9:
4730 divided by 580 is 8 with a remainder of 90.
The next digit of our result is 8. 
Result so far: 27005.8
The remainder is 90 after subtracting 4640 from 4730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 10:
580 can be fit into 900 1 times, resulting in a remainder of 320.
The next digit of our result is 1. 
Result so far: 27005.81
The remainder is 320 after subtracting 580 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 11:
The number 580 fits into 3200 5 times, leaving a remainder of 300.
The next digit of our result is 5. 
Result so far: 27005.815
The remainder is 300 after subtracting 2900 from 3200.
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 12:
If we divide 3000 by 580, we get 5 and a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 27005.8155
Deduct 2900 from 3000 and we're left 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.

In conclusion, the division gives 27005.8155 with a balance of 0.001.
