We look at the division of 7219080 by 664 
The aim is to understand the frequency of 664 in 7219080.

Let's proceed to step 1:
The number 664 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 664

Advancing to step 2:
When dividing 72 by 664, we get 0 with a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Grab the next digit (1) from the dividend, add it to 72, then carry on: 721 / 664

Moving on to step 3:
664 goes into 721 1 times with a remainder of 57.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 664 from 721 to get 57.
Grab the next digit (9) from the dividend, add it to 57, then carry on: 579 / 664

Moving on to step 4:
If we divide 579 by 664, we get 0 and a remainder of 579.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 579, we end up with 579.
Append the next digit (0) from the dividend to 579 and continue with: 5790 / 664

Moving on to step 5:
When dividing 5790 by 664, we get 8 with a remainder of 478.
The number 8 becomes the next digit in our result. 
Result so far: 108.0
Subtracting 5312 from 5790 leaves us with 478.
Take the next digit (8) from the dividend and append it to 478, then repeat: 4788 / 664

Advancing to step 6:
664 goes into 4788 7 times with a remainder of 140.
The next digit of our result is 7. 
Result so far: 1087.0
If we subtract 4648 from 4788, we get 140.
Include the next digit (0) from the dividend after 140, then repeat: 1400 / 664

Let's proceed to step 7:
1400 divided by 664 is 2 with a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 10872.0
Deduct 1328 from 1400 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 8:
664 can be fit into 720 1 times, resulting in a remainder of 56.
The number 1 becomes the next digit in our result. 
Result so far: 10872.1
Subtract 664 from 720 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 9:
560 divided by 664 is 0 with a remainder of 560.
Put 0 as the next digit of the answer. 
Result so far: 10872.1
Subtract 0 from 560 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 10:
664 goes into 5600 8 times with a remainder of 288.
Use 8 as the next digit of our solution. 
Result so far: 10872.108
The remainder is 288 after subtracting 5312 from 5600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 11:
If we divide 2880 by 664, we get 4 and a remainder of 224.
Record the quotient 4 as the next digit in the result. 
Result so far: 10872.1084
Subtract 2656 from 2880 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 12:
When dividing 2240 by 664, we get 3 with a remainder of 248.
The next digit of our result is 3. 
Result so far: 10872.10843
The remainder is 248 after subtracting 1992 from 2240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Step 13:
The number 664 fits into 2480 3 times, leaving a remainder of 488.
The number 3 becomes the next digit in our result. 
Result so far: 10872.108433
If we take 1992 away from 2480, we end up with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

In conclusion, the division gives 10872.108433 with a balance of 4.88e-05.
