We divide 485017 by 20
The aim is to understand the frequency of 20 in 485017.

On to step 1:
20 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 20

On to step 2:
If we divide 48 by 20, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 40 from 48 to get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 20

Step 3:
The number 20 fits into 85 4 times, leaving a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 24.0
If we subtract 80 from 85, we get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 20

Let's proceed to step 4:
When dividing 50 by 20, we get 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 242.0
If we subtract 40 from 50, we get 10.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 20

Going ahead to step 5:
101 divided by 20 is 5 with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 2425.0
If we take 100 away from 101, we end up with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 20

Advancing to step 6:
When dividing 17 by 20, we get 0 with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 24250.0
If we subtract 0 from 17, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 7:
If we divide 170 by 20, we get 8 and a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 24250.8
Subtract 160 from 170 to 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.

Advancing to step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 24250.85
If we take 100 away from 100, 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.

Let's proceed to step 9:
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: 24250.85
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.

Advancing to step 10:
20 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 24250.85
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 24250.85, and the remainder is 0.0.
