We're dividing 20565592 by 580 
Let's see how many times 580 fits into 20565592.

Step 1:
2 divided by 580 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 580

Advancing to step 2:
580 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Bring next digit (5) of the dividend behind the 20 and repeat the process: 205 / 580

On to step 3:
When dividing 205 by 580, we get 0 with a remainder of 205.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 205 and we're left with 205.
Grab the next digit (6) from the dividend, add it to 205, then carry on: 2056 / 580

Let's proceed to step 4:
If we divide 2056 by 580, we get 3 and a remainder of 316.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 1740 away from 2056, we end up with 316.
Append the next digit (5) from the dividend to 316 and continue with: 3165 / 580

Moving on to step 5:
580 can be fit into 3165 5 times, resulting in a remainder of 265.
Write down 5 as next digit of the result. 
Result so far: 35.0
Deduct 2900 from 3165 and we're left with 265.
Take the next digit (5) from the dividend and append it to 265, then repeat: 2655 / 580

Step 6:
If we divide 2655 by 580, we get 4 and a remainder of 335.
Use 4 as the next digit of our solution. 
Result so far: 354.0
Deduct 2320 from 2655 and we're left with 335.
Take the next digit (9) from the dividend and append it to 335, then repeat: 3359 / 580

On to step 7:
3359 divided by 580 is 5 with a remainder of 459.
The next digit of our result is 5. 
Result so far: 3545.0
If we subtract 2900 from 3359, we get 459.
Fetch the next digit (2) from the dividend, attach it to 459 and continue: 4592 / 580

Moving on to step 8:
4592 divided by 580 is 7 with a remainder of 532.
The number 7 becomes the next digit in our result. 
Result so far: 35457.0
Subtract 4060 from 4592 to get 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Going ahead to step 9:
580 can be fit into 5320 9 times, resulting in a remainder of 100.
Put 9 as the next digit of the answer. 
Result so far: 35457.9
If we subtract 5220 from 5320, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 10:
580 can be fit into 1000 1 times, resulting in a remainder of 420.
The next digit of our result is 1. 
Result so far: 35457.91
Deduct 580 from 1000 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 11:
If we divide 4200 by 580, we get 7 and a remainder of 140.
Use 7 as the next digit of our solution. 
Result so far: 35457.917
If we subtract 4060 from 4200, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 12:
The number 580 fits into 1400 2 times, leaving a remainder of 240.
The number 2 becomes the next digit in our result. 
Result so far: 35457.9172
Subtract 1160 from 1400 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 13:
2400 divided by 580 is 4 with a remainder of 80.
The number 4 becomes the next digit in our result. 
Result so far: 35457.91724
If we subtract 2320 from 2400, 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.

Going ahead to step 14:
If we divide 800 by 580, we get 1 and a remainder of 220.
The next digit of our result is 1. 
Result so far: 35457.917241
Deduct 580 from 800 and we're left 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.

Let's proceed to step 15:
580 goes into 2200 3 times with a remainder of 460.
Write down 3 as next digit of the result. 
Result so far: 35457.9172413
If we subtract 1740 from 2200, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 16:
4600 divided by 580 is 7 with a remainder of 540.
Write down 7 as next digit of the result. 
Result so far: 35457.91724137
Deduct 4060 from 4600 and we're left with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

The final result is 35457.91724137 with a remainder of 5.4e-07.
