We look at the division of 946868 by 20 
The aim is to understand the frequency of 20 in 946868.

Moving on to step 1:
20 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 20

Advancing to step 2:
When dividing 94 by 20, we get 4 with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 80 from 94 and we're left with 14.
Include the next digit (6) from the dividend after 14, then repeat: 146 / 20

Let's proceed to step 3:
When dividing 146 by 20, we get 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 47.0
If we take 140 away from 146, we end up with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 20

Advancing to step 4:
68 divided by 20 is 3 with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 473.0
Deduct 60 from 68 and we're left with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 20

Advancing to step 5:
The number 20 fits into 86 4 times, leaving a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 4734.0
Subtract 80 from 86 to get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 20

Step 6:
If we divide 68 by 20, we get 3 and a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 47343.0
If we take 60 away from 68, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
If we divide 80 by 20, we get 4 and a remainder of 0.
The next digit of our result is 4. 
Result so far: 47343.4
If we subtract 80 from 80, 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 8:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 47343.4
If we take 0 away from 0, 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.

Step 9:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 47343.4
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 result is 47343.4 with a remainder of 0.0.
