456072 divided by 20 
Let's see how many times 20 fits into 456072.

Let's proceed to step 1:
20 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 20

Let's proceed to step 2:
45 divided by 20 is 2 with a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 40 away from 45, we end up with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 20

Step 3:
20 can be fit into 56 2 times, resulting in a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we take 40 away from 56, we end up with 16.
Fetch the next digit (0) from the dividend, attach it to 16 and continue: 160 / 20

Moving on to step 4:
When dividing 160 by 20, we get 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 228.0
Subtract 160 from 160 to get 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 20

On to step 5:
When dividing 7 by 20, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 2280.0
Subtract 0 from 7 to get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 20

Advancing to step 6:
20 goes into 72 3 times with a remainder of 12.
The next digit of our result is 3. 
Result so far: 22803.0
If we take 60 away from 72, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
The number 20 fits into 120 6 times, leaving a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 22803.6
If we subtract 120 from 120, 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 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 22803.6
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.

On to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 22803.6
If we take 0 away from 0, we end up 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 22803.6, with a leftover of 0.0.
