We look at the division of 54756680 by 20 
The aim is to understand the frequency of 20 in 54756680.

Let's proceed to step 1:
The number 20 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 20

Going ahead to step 2:
The number 20 fits into 54 2 times, leaving a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 40 from 54 to get 14.
Bring next digit (7) of the dividend behind the 14 and repeat the process: 147 / 20

Let's proceed to step 3:
The number 20 fits into 147 7 times, leaving a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 27.0
Deduct 140 from 147 and we're left with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 20

Moving on to step 4:
The number 20 fits into 75 3 times, leaving a remainder of 15.
The next digit of our result is 3. 
Result so far: 273.0
Subtracting 60 from 75 leaves us with 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 20

Step 5:
156 divided by 20 is 7 with a remainder of 16.
The next digit of our result is 7. 
Result so far: 2737.0
The remainder is 16 after subtracting 140 from 156.
Take the next digit (6) from the dividend and append it to 16, then repeat: 166 / 20

On to step 6:
20 goes into 166 8 times with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 27378.0
If we take 160 away from 166, we end up with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 20

On to step 7:
The number 20 fits into 68 3 times, leaving a remainder of 8.
The next digit of our result is 3. 
Result so far: 273783.0
If we subtract 60 from 68, we get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 20

Going ahead to step 8:
The number 20 fits into 80 4 times, leaving a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 2737834.0
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.

Step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2737834.0
Subtract 0 from 0 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.

On to step 10:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2737834.0
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.

The quotient of the division is 2737834.0, and the remainder is 0.0.
