450442 divided by 20 
The aim is to understand the frequency of 20 in 450442.

Going ahead 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
Subtracting 0 from 4 leaves us with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 20

Advancing 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
Subtract 40 from 45 to get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 20

Step 3:
20 can be fit into 50 2 times, resulting in a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we subtract 40 from 50, we get 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 20

On to step 4:
When dividing 104 by 20, we get 5 with a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 225.0
Deduct 100 from 104 and we're left with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 20

Step 5:
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: 2252.0
The remainder is 4 after subtracting 40 from 44.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 20

Step 6:
20 goes into 42 2 times with a remainder of 2.
The next digit of our result is 2. 
Result so far: 22522.0
The remainder is 2 after subtracting 40 from 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
20 divided by 20 is 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 22522.1
Subtracting 20 from 20 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.
The number 0 becomes the next digit in our result. 
Result so far: 22522.1
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 9:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 22522.1
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.

The quotient of the division is 22522.1, and the remainder is 0.0.
