We're dividing 468503 by 20 
We're looking to find how many times 20 goes into 468503.

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
Subtract 0 from 4 to get 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 20

On to step 2:
If we divide 46 by 20, we get 2 and a remainder of 6.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 6 after subtracting 40 from 46.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 20

Let's proceed to step 3:
If we divide 68 by 20, we get 3 and a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
The remainder is 8 after subtracting 60 from 68.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 20

Step 4:
20 goes into 85 4 times with a remainder of 5.
The next digit of our result is 4. 
Result so far: 234.0
Subtracting 80 from 85 leaves us with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 20

Step 5:
When dividing 50 by 20, we get 2 with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 2342.0
If we take 40 away from 50, we end up with 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 20

Step 6:
The number 20 fits into 103 5 times, leaving a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 23425.0
If we subtract 100 from 103, 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.

Let's proceed to step 7:
20 can be fit into 30 1 times, resulting in a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 23425.1
Deduct 20 from 30 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.

Moving on to step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 23425.15
Deduct 100 from 100 and we're left 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 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 23425.15
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.

Let's proceed to step 10:
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: 23425.15
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.

In conclusion, the division gives 23425.15 with a balance of 0.0.
