89193791 divided by 664 
The aim is to understand the frequency of 664 in 89193791.

Moving on to step 1:
If we divide 8 by 664, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 664

Going ahead to step 2:
When dividing 89 by 664, we get 0 with a remainder of 89.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 89 after subtracting 0 from 89.
Grab the next digit (1) from the dividend, add it to 89, then carry on: 891 / 664

Going ahead to step 3:
664 can be fit into 891 1 times, resulting in a remainder of 227.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 664 from 891 to get 227.
Append the next digit (9) from the dividend to 227 and continue with: 2279 / 664

Moving on to step 4:
2279 divided by 664 is 3 with a remainder of 287.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 287 after subtracting 1992 from 2279.
Append the next digit (3) from the dividend to 287 and continue with: 2873 / 664

Let's proceed to step 5:
If we divide 2873 by 664, we get 4 and a remainder of 217.
Record the quotient 4 as the next digit in the result. 
Result so far: 134.0
Subtracting 2656 from 2873 leaves us with 217.
Grab the next digit (7) from the dividend, add it to 217, then carry on: 2177 / 664

Step 6:
664 goes into 2177 3 times with a remainder of 185.
Record the quotient 3 as the next digit in the result. 
Result so far: 1343.0
The remainder is 185 after subtracting 1992 from 2177.
Bring next digit (9) of the dividend behind the 185 and repeat the process: 1859 / 664

Advancing to step 7:
664 goes into 1859 2 times with a remainder of 531.
Put 2 as the next digit of the answer. 
Result so far: 13432.0
The remainder is 531 after subtracting 1328 from 1859.
Append the next digit (1) from the dividend to 531 and continue with: 5311 / 664

Advancing to step 8:
The number 664 fits into 5311 7 times, leaving a remainder of 663.
Put 7 as the next digit of the answer. 
Result so far: 134327.0
The remainder is 663 after subtracting 4648 from 5311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6630, and continue the process.

Advancing to step 9:
The number 664 fits into 6630 9 times, leaving a remainder of 654.
The next digit of our result is 9. 
Result so far: 134327.9
The remainder is 654 after subtracting 5976 from 6630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Going ahead to step 10:
When dividing 6540 by 664, we get 9 with a remainder of 564.
Record the quotient 9 as the next digit in the result. 
Result so far: 134327.99
Subtracting 5976 from 6540 leaves us with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Our division results in 134327.99 with a remaining 0.564.
