We look at the division of 476700 by 20 
The aim is to understand the frequency of 20 in 476700.

Step 1:
When dividing 4 by 20, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 20

Moving 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
Subtract 40 from 47 to get 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 20

Moving on to step 3:
The number 20 fits into 76 3 times, leaving a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
The remainder is 16 after subtracting 60 from 76.
Bring next digit (7) of the dividend behind the 16 and repeat the process: 167 / 20

On to step 4:
When dividing 167 by 20, we get 8 with a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 238.0
Subtract 160 from 167 to get 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 20

Advancing to step 5:
70 divided by 20 is 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 2383.0
Deduct 60 from 70 and we're left with 10.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 20

Let's proceed to step 6:
100 divided by 20 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 23835.0
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.

Moving on to step 7:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 23835.0
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.

Let's proceed to step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 23835.0
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.

The final outcome is 23835.0, with a leftover of 0.0.
