We're dividing 20580523 by 578 
We're looking to find how many times 578 goes into 20580523.

Going ahead to step 1:
The number 578 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 578

Advancing to step 2:
The number 578 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Grab the next digit (5) from the dividend, add it to 20, then carry on: 205 / 578

Step 3:
The number 578 fits into 205 0 times, leaving a remainder of 205.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 205, we get 205.
Grab the next digit (8) from the dividend, add it to 205, then carry on: 2058 / 578

Going ahead to step 4:
The number 578 fits into 2058 3 times, leaving a remainder of 324.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 1734 away from 2058, we end up with 324.
Include the next digit (0) from the dividend after 324, then repeat: 3240 / 578

Advancing to step 5:
578 can be fit into 3240 5 times, resulting in a remainder of 350.
Write down 5 as next digit of the result. 
Result so far: 35.0
If we take 2890 away from 3240, we end up with 350.
Take the next digit (5) from the dividend and append it to 350, then repeat: 3505 / 578

Advancing to step 6:
578 can be fit into 3505 6 times, resulting in a remainder of 37.
Use 6 as the next digit of our solution. 
Result so far: 356.0
Deduct 3468 from 3505 and we're left with 37.
Fetch the next digit (2) from the dividend, attach it to 37 and continue: 372 / 578

On to step 7:
When dividing 372 by 578, we get 0 with a remainder of 372.
Use 0 as the next digit of our solution. 
Result so far: 3560.0
If we take 0 away from 372, we end up with 372.
Take the next digit (3) from the dividend and append it to 372, then repeat: 3723 / 578

Advancing to step 8:
578 goes into 3723 6 times with a remainder of 255.
Put 6 as the next digit of the answer. 
Result so far: 35606.0
The remainder is 255 after subtracting 3468 from 3723.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Going ahead to step 9:
The number 578 fits into 2550 4 times, leaving a remainder of 238.
Use 4 as the next digit of our solution. 
Result so far: 35606.4
Subtracting 2312 from 2550 leaves us with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 10:
2380 divided by 578 is 4 with a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 35606.44
Deduct 2312 from 2380 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

In conclusion, the division gives 35606.44 with a balance of 0.068.
