Let's divide 456413 by 20
The aim is to understand the frequency of 20 in 456413.

On to step 1:
20 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 20

Step 2:
If we divide 45 by 20, we get 2 and a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 40 from 45 to get 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 20

Moving on to step 3:
56 divided by 20 is 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Deduct 40 from 56 and we're left with 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 20

Let's proceed to step 4:
The number 20 fits into 164 8 times, leaving a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 228.0
Deduct 160 from 164 and we're left with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 20

On to step 5:
If we divide 41 by 20, we get 2 and a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2282.0
If we take 40 away from 41, we end up with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 20

Moving on to step 6:
20 goes into 13 0 times with a remainder of 13.
The next digit of our result is 0. 
Result so far: 22820.0
Subtract 0 from 13 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
20 can be fit into 130 6 times, resulting in a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 22820.6
Deduct 120 from 130 and we're left 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.
Record the quotient 5 as the next digit in the result. 
Result so far: 22820.65
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.

Step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 22820.65
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.

On to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 22820.65
If we subtract 0 from 0, 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.

In conclusion, the division gives 22820.65 with a balance of 0.0.
