Let's divide 24570 by 20
Let's see how many times 20 fits into 24570.

On to step 1:
20 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 20

Advancing to step 2:
20 goes into 24 1 times with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 4 after subtracting 20 from 24.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 20

Step 3:
The number 20 fits into 45 2 times, leaving a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 40 from 45, we get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 20

Step 4:
20 can be fit into 57 2 times, resulting in a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 122.0
The remainder is 17 after subtracting 40 from 57.
Take the next digit (0) from the dividend and append it to 17, then repeat: 170 / 20

Advancing to step 5:
The number 20 fits into 170 8 times, leaving a remainder of 10.
The next digit of our result is 8. 
Result so far: 1228.0
Deduct 160 from 170 and we're left 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.

Let's proceed to step 6:
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: 1228.5
Subtract 100 from 100 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 7:
If we divide 0 by 20, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1228.5
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.

Going ahead to step 8:
0 divided by 20 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1228.5
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 outcome is 1228.5, with a leftover of 0.0.
