20621692 divided by 480 
The aim is to understand the frequency of 480 in 20621692.

Going ahead to step 1:
The number 480 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 480

Let's proceed to step 2:
480 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 480

On to step 3:
480 can be fit into 206 0 times, resulting in a remainder of 206.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 206 to get 206.
Take the next digit (2) from the dividend and append it to 206, then repeat: 2062 / 480

Going ahead to step 4:
480 can be fit into 2062 4 times, resulting in a remainder of 142.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 1920 from 2062, we get 142.
Grab the next digit (1) from the dividend, add it to 142, then carry on: 1421 / 480

Step 5:
480 can be fit into 1421 2 times, resulting in a remainder of 461.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
The remainder is 461 after subtracting 960 from 1421.
Append the next digit (6) from the dividend to 461 and continue with: 4616 / 480

On to step 6:
When dividing 4616 by 480, we get 9 with a remainder of 296.
Write down 9 as next digit of the result. 
Result so far: 429.0
If we take 4320 away from 4616, we end up with 296.
Bring next digit (9) of the dividend behind the 296 and repeat the process: 2969 / 480

Step 7:
480 can be fit into 2969 6 times, resulting in a remainder of 89.
Use 6 as the next digit of our solution. 
Result so far: 4296.0
If we take 2880 away from 2969, we end up with 89.
Include the next digit (2) from the dividend after 89, then repeat: 892 / 480

Moving on to step 8:
892 divided by 480 is 1 with a remainder of 412.
The number 1 becomes the next digit in our result. 
Result so far: 42961.0
Deduct 480 from 892 and we're left with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Moving on to step 9:
When dividing 4120 by 480, we get 8 with a remainder of 280.
The number 8 becomes the next digit in our result. 
Result so far: 42961.8
If we subtract 3840 from 4120, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 10:
If we divide 2800 by 480, we get 5 and a remainder of 400.
Use 5 as the next digit of our solution. 
Result so far: 42961.85
Subtracting 2400 from 2800 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 11:
4000 divided by 480 is 8 with a remainder of 160.
Record the quotient 8 as the next digit in the result. 
Result so far: 42961.858
If we subtract 3840 from 4000, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 12:
1600 divided by 480 is 3 with a remainder of 160.
Write down 3 as next digit of the result. 
Result so far: 42961.8583
If we subtract 1440 from 1600, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 13:
480 goes into 1600 3 times with a remainder of 160.
Write down 3 as next digit of the result. 
Result so far: 42961.85833
Subtracting 1440 from 1600 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Our division results in 42961.85833 with a remaining 0.00016.
