577723 divided by 20 
We want to figure out the number of times 577723 can be divided by 20.

Going ahead to step 1:
If we divide 5 by 20, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 20

Moving on to step 2:
If we divide 57 by 20, we get 2 and a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 40 away from 57, we end up with 17.
Bring next digit (7) of the dividend behind the 17 and repeat the process: 177 / 20

Going ahead to step 3:
If we divide 177 by 20, we get 8 and a remainder of 17.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Deduct 160 from 177 and we're left with 17.
Fetch the next digit (7) from the dividend, attach it to 17 and continue: 177 / 20

Going ahead to step 4:
The number 20 fits into 177 8 times, leaving a remainder of 17.
The next digit of our result is 8. 
Result so far: 288.0
The remainder is 17 after subtracting 160 from 177.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 20

Going ahead to step 5:
The number 20 fits into 172 8 times, leaving a remainder of 12.
The next digit of our result is 8. 
Result so far: 2888.0
Subtracting 160 from 172 leaves us with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 20

Advancing to step 6:
The number 20 fits into 123 6 times, leaving a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 28886.0
If we subtract 120 from 123, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
The number 20 fits into 30 1 times, leaving a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 28886.1
If we subtract 20 from 30, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 28886.15
Subtracting 100 from 100 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
20 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 28886.15
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 28886.15
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 28886.15 and a remainder of 0.0.
