We divide 485250 by 20
We want to divide 485250 by 20.

Let's proceed to step 1:
20 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 20

Step 2:
The number 20 fits into 48 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 40 from 48, we get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 20

Advancing to step 3:
20 goes into 85 4 times with a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Subtracting 80 from 85 leaves us with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 20

Advancing to step 4:
52 divided by 20 is 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 242.0
If we take 40 away from 52, we end up with 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 20

On to step 5:
If we divide 125 by 20, we get 6 and a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 2426.0
The remainder is 5 after subtracting 120 from 125.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 20

Advancing to step 6:
20 goes into 50 2 times with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 24262.0
If we take 40 away from 50, we end up 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.

Moving on to step 7:
20 goes into 100 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 24262.5
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.

Advancing to step 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 24262.5
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.

Step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 24262.5
If we subtract 0 from 0, we 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.

The final result is 24262.5 with a remainder of 0.0.
