We divide 464439 by 20
We want to figure out the number of times 464439 can be divided by 20.

Moving on to step 1:
The number 20 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 20

Let's proceed to step 2:
46 divided by 20 is 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 6 after subtracting 40 from 46.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 20

Going ahead to step 3:
64 divided by 20 is 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Subtract 60 from 64 to get 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 20

Going ahead to step 4:
20 can be fit into 44 2 times, resulting in a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 232.0
If we subtract 40 from 44, we get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 20

On to step 5:
The number 20 fits into 43 2 times, leaving a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 2322.0
If we subtract 40 from 43, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 20

Step 6:
39 divided by 20 is 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 23221.0
If we take 20 away from 39, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
20 can be fit into 190 9 times, resulting in a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 23221.9
If we take 180 away from 190, 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.

On to step 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 23221.95
If we subtract 100 from 100, 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.

Step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 23221.95
Deduct 0 from 0 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.

Going ahead to step 10:
0 divided by 20 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 23221.95
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.

The quotient of the division is 23221.95, and the remainder is 0.0.
