We divide 581788 by 20
Let's see how many times 20 fits into 581788.

Moving on to step 1:
The number 20 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 20

Going ahead to step 2:
20 goes into 58 2 times with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 40 from 58 to get 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 20

Let's proceed to step 3:
20 goes into 181 9 times with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 29.0
Subtracting 180 from 181 leaves us with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 20

Let's proceed to step 4:
20 can be fit into 17 0 times, resulting in a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 290.0
Subtracting 0 from 17 leaves us with 17.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 20

Advancing to step 5:
The number 20 fits into 178 8 times, leaving a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 2908.0
The remainder is 18 after subtracting 160 from 178.
Bring next digit (8) of the dividend behind the 18 and repeat the process: 188 / 20

Advancing to step 6:
20 can be fit into 188 9 times, resulting in a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 29089.0
If we take 180 away from 188, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
If we divide 80 by 20, we get 4 and a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 29089.4
If we take 80 away from 80, 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.

Moving on to step 8:
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: 29089.4
Subtracting 0 from 0 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.
The next digit of our result is 0. 
Result so far: 29089.4
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 29089.4 with a remainder of 0.0.
