664294 ÷ 89 
The aim is to understand the frequency of 89 in 664294.

Step 1:
The number 89 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 89

Moving on to step 2:
The number 89 fits into 66 0 times, leaving a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Bring next digit (4) of the dividend behind the 66 and repeat the process: 664 / 89

Let's proceed to step 3:
When dividing 664 by 89, we get 7 with a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 623 away from 664, we end up with 41.
Fetch the next digit (2) from the dividend, attach it to 41 and continue: 412 / 89

Going ahead to step 4:
When dividing 412 by 89, we get 4 with a remainder of 56.
The next digit of our result is 4. 
Result so far: 74.0
If we take 356 away from 412, we end up with 56.
Include the next digit (9) from the dividend after 56, then repeat: 569 / 89

Going ahead to step 5:
When dividing 569 by 89, we get 6 with a remainder of 35.
Put 6 as the next digit of the answer. 
Result so far: 746.0
The remainder is 35 after subtracting 534 from 569.
Append the next digit (4) from the dividend to 35 and continue with: 354 / 89

Going ahead to step 6:
89 can be fit into 354 3 times, resulting in a remainder of 87.
The next digit of our result is 3. 
Result so far: 7463.0
The remainder is 87 after subtracting 267 from 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 7:
The number 89 fits into 870 9 times, leaving a remainder of 69.
Record the quotient 9 as the next digit in the result. 
Result so far: 7463.9
Subtract 801 from 870 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 8:
89 can be fit into 690 7 times, resulting in a remainder of 67.
The number 7 becomes the next digit in our result. 
Result so far: 7463.97
Subtracting 623 from 690 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 9:
If we divide 670 by 89, we get 7 and a remainder of 47.
The next digit of our result is 7. 
Result so far: 7463.977
If we subtract 623 from 670, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The final outcome is 7463.977, with a leftover of 0.0047.
