463375 divided by 20 
The aim is to understand the frequency of 20 in 463375.

On to step 1:
If we divide 4 by 20, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 20

Moving on to step 2:
46 divided by 20 is 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 40 from 46, we get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 20

Let's proceed to step 3:
If we divide 63 by 20, we get 3 and a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtract 60 from 63 to get 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 20

Going ahead to step 4:
20 goes into 33 1 times with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 231.0
If we subtract 20 from 33, we get 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 20

Let's proceed to step 5:
If we divide 137 by 20, we get 6 and a remainder of 17.
Use 6 as the next digit of our solution. 
Result so far: 2316.0
The remainder is 17 after subtracting 120 from 137.
Fetch the next digit (5) from the dividend, attach it to 17 and continue: 175 / 20

Step 6:
If we divide 175 by 20, we get 8 and a remainder of 15.
Write down 8 as next digit of the result. 
Result so far: 23168.0
If we subtract 160 from 175, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
150 divided by 20 is 7 with a remainder of 10.
The next digit of our result is 7. 
Result so far: 23168.7
If we take 140 away from 150, 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.

Moving on to step 8:
100 divided by 20 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 23168.75
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.

Going ahead to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 23168.75
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.

Going ahead to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 23168.75
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.

The final result is 23168.75 with a remainder of 0.0.
