473471 divided by 20 
The aim is to understand the frequency of 20 in 473471.

Let's proceed to step 1:
4 divided by 20 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 20

On to step 2:
When dividing 47 by 20, we get 2 with a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 40 from 47 and we're left with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 20

Going ahead to step 3:
If we divide 73 by 20, we get 3 and a remainder of 13.
The next digit of our result is 3. 
Result so far: 23.0
Subtract 60 from 73 to get 13.
Fetch the next digit (4) from the dividend, attach it to 13 and continue: 134 / 20

Advancing to step 4:
If we divide 134 by 20, we get 6 and a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 236.0
If we take 120 away from 134, we end up with 14.
Append the next digit (7) from the dividend to 14 and continue with: 147 / 20

Advancing to step 5:
20 can be fit into 147 7 times, resulting in a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 2367.0
The remainder is 7 after subtracting 140 from 147.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 20

Let's proceed to step 6:
If we divide 71 by 20, we get 3 and a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 23673.0
Subtracting 60 from 71 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
If we divide 110 by 20, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 23673.5
If we take 100 away from 110, 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:
If we divide 100 by 20, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 23673.55
Subtract 100 from 100 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.

The final result is 23673.55 with a remainder of 0.0.
