We look at the division of 67763491 by 808 
The aim is to understand the frequency of 808 in 67763491.

Let's proceed to step 1:
The number 808 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 808

Going ahead to step 2:
If we divide 67 by 808, we get 0 and a remainder of 67.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 67 and we're left with 67.
Include the next digit (7) from the dividend after 67, then repeat: 677 / 808

Step 3:
808 goes into 677 0 times with a remainder of 677.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 677 to get 677.
Take the next digit (6) from the dividend and append it to 677, then repeat: 6776 / 808

Step 4:
808 goes into 6776 8 times with a remainder of 312.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 6464 away from 6776, we end up with 312.
Grab the next digit (3) from the dividend, add it to 312, then carry on: 3123 / 808

Step 5:
808 goes into 3123 3 times with a remainder of 699.
Use 3 as the next digit of our solution. 
Result so far: 83.0
If we subtract 2424 from 3123, we get 699.
Bring next digit (4) of the dividend behind the 699 and repeat the process: 6994 / 808

Step 6:
808 goes into 6994 8 times with a remainder of 530.
The number 8 becomes the next digit in our result. 
Result so far: 838.0
Subtract 6464 from 6994 to get 530.
Take the next digit (9) from the dividend and append it to 530, then repeat: 5309 / 808

Moving on to step 7:
5309 divided by 808 is 6 with a remainder of 461.
Record the quotient 6 as the next digit in the result. 
Result so far: 8386.0
Subtract 4848 from 5309 to get 461.
Grab the next digit (1) from the dividend, add it to 461, then carry on: 4611 / 808

On to step 8:
808 can be fit into 4611 5 times, resulting in a remainder of 571.
Put 5 as the next digit of the answer. 
Result so far: 83865.0
Deduct 4040 from 4611 and we're left with 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

Advancing to step 9:
The number 808 fits into 5710 7 times, leaving a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 83865.7
If we subtract 5656 from 5710, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 10:
808 can be fit into 540 0 times, resulting in a remainder of 540.
The next digit of our result is 0. 
Result so far: 83865.7
If we subtract 0 from 540, we get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Step 11:
5400 divided by 808 is 6 with a remainder of 552.
The number 6 becomes the next digit in our result. 
Result so far: 83865.706
Subtracting 4848 from 5400 leaves us with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

On to step 12:
808 can be fit into 5520 6 times, resulting in a remainder of 672.
Write down 6 as next digit of the result. 
Result so far: 83865.7066
If we subtract 4848 from 5520, we get 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

The final result is 83865.7066 with a remainder of 0.00672.
