Let's divide 483590 by 20
Let's see how many times 20 fits into 483590.

Let's proceed to step 1:
If we divide 4 by 20, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 20

Advancing to step 2:
20 goes into 48 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 40 from 48, we get 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 20

Moving on to step 3:
20 goes into 83 4 times with a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 24.0
The remainder is 3 after subtracting 80 from 83.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 20

Let's proceed to step 4:
20 can be fit into 35 1 times, resulting in a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 241.0
Subtract 20 from 35 to get 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 20

Moving on to step 5:
When dividing 159 by 20, we get 7 with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 2417.0
Subtract 140 from 159 to get 19.
Fetch the next digit (0) from the dividend, attach it to 19 and continue: 190 / 20

Step 6:
The number 20 fits into 190 9 times, leaving a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 24179.0
Subtracting 180 from 190 leaves us with 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 7:
If we divide 100 by 20, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 24179.5
The remainder is 0 after subtracting 100 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 24179.5
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.

Moving on to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 24179.5
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.

The final result is 24179.5 with a remainder of 0.0.
