20707188 divided by 808 
The aim is to understand the frequency of 808 in 20707188.

Advancing to step 1:
2 divided by 808 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
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 / 808

On to step 2:
If we divide 20 by 808, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Bring next digit (7) of the dividend behind the 20 and repeat the process: 207 / 808

Step 3:
When dividing 207 by 808, we get 0 with a remainder of 207.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 207, we get 207.
Grab the next digit (0) from the dividend, add it to 207, then carry on: 2070 / 808

Moving on to step 4:
When dividing 2070 by 808, we get 2 with a remainder of 454.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 1616 from 2070 leaves us with 454.
Include the next digit (7) from the dividend after 454, then repeat: 4547 / 808

Advancing to step 5:
808 can be fit into 4547 5 times, resulting in a remainder of 507.
The next digit of our result is 5. 
Result so far: 25.0
The remainder is 507 after subtracting 4040 from 4547.
Append the next digit (1) from the dividend to 507 and continue with: 5071 / 808

Let's proceed to step 6:
When dividing 5071 by 808, we get 6 with a remainder of 223.
Put 6 as the next digit of the answer. 
Result so far: 256.0
If we take 4848 away from 5071, we end up with 223.
Include the next digit (8) from the dividend after 223, then repeat: 2238 / 808

Going ahead to step 7:
The number 808 fits into 2238 2 times, leaving a remainder of 622.
Write down 2 as next digit of the result. 
Result so far: 2562.0
If we subtract 1616 from 2238, we get 622.
Include the next digit (8) from the dividend after 622, then repeat: 6228 / 808

Step 8:
808 can be fit into 6228 7 times, resulting in a remainder of 572.
Record the quotient 7 as the next digit in the result. 
Result so far: 25627.0
Subtracting 5656 from 6228 leaves us with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Moving on to step 9:
808 can be fit into 5720 7 times, resulting in a remainder of 64.
Record the quotient 7 as the next digit in the result. 
Result so far: 25627.7
Subtracting 5656 from 5720 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 10:
808 goes into 640 0 times with a remainder of 640.
Use 0 as the next digit of our solution. 
Result so far: 25627.7
Subtracting 0 from 640 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

On to step 11:
6400 divided by 808 is 7 with a remainder of 744.
The next digit of our result is 7. 
Result so far: 25627.707
Subtracting 5656 from 6400 leaves us with 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

Advancing to step 12:
808 can be fit into 7440 9 times, resulting in a remainder of 168.
The number 9 becomes the next digit in our result. 
Result so far: 25627.7079
Subtracting 7272 from 7440 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Moving on to step 13:
The number 808 fits into 1680 2 times, leaving a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 25627.70792
The remainder is 64 after subtracting 1616 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 14:
When dividing 640 by 808, we get 0 with a remainder of 640.
Record the quotient 0 as the next digit in the result. 
Result so far: 25627.70792
Deduct 0 from 640 and we're left with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 15:
The number 808 fits into 6400 7 times, leaving a remainder of 744.
The number 7 becomes the next digit in our result. 
Result so far: 25627.7079207
The remainder is 744 after subtracting 5656 from 6400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

Step 16:
When dividing 7440 by 808, we get 9 with a remainder of 168.
The next digit of our result is 9. 
Result so far: 25627.70792079
The remainder is 168 after subtracting 7272 from 7440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Our division results in 25627.70792079 with a remaining 1.68e-07.
