We divide 464245 by 20
Let's see how many times 20 fits into 464245.

Moving on to step 1:
The number 20 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 20

Moving on to step 2:
46 divided by 20 is 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 40 from 46 to get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 20

Let's proceed to step 3:
When dividing 64 by 20, we get 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 23.0
Deduct 60 from 64 and we're left with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 20

Moving on to step 4:
20 goes into 42 2 times with a remainder of 2.
The next digit of our result is 2. 
Result so far: 232.0
Subtract 40 from 42 to get 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 20

Step 5:
When dividing 24 by 20, we get 1 with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 2321.0
The remainder is 4 after subtracting 20 from 24.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 20

Going ahead to step 6:
20 can be fit into 45 2 times, resulting in a remainder of 5.
The next digit of our result is 2. 
Result so far: 23212.0
If we take 40 away from 45, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
The number 20 fits into 50 2 times, leaving a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 23212.2
If we subtract 40 from 50, we get 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:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 23212.25
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.

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: 23212.25
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 10:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 23212.25
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.

After the division, we end up with 23212.25 and a remainder of 0.0.
