We're dividing 662666 by 89 
The aim is to understand the frequency of 89 in 662666.

Moving on to step 1:
If we divide 6 by 89, we get 0 and a remainder of 6.
The next digit of our result is 0. 
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

Advancing to step 2:
If we divide 66 by 89, we get 0 and a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Fetch the next digit (2) from the dividend, attach it to 66 and continue: 662 / 89

Moving on to step 3:
662 divided by 89 is 7 with a remainder of 39.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 39 after subtracting 623 from 662.
Append the next digit (6) from the dividend to 39 and continue with: 396 / 89

Moving on to step 4:
When dividing 396 by 89, we get 4 with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 74.0
Subtracting 356 from 396 leaves us with 40.
Include the next digit (6) from the dividend after 40, then repeat: 406 / 89

Step 5:
89 goes into 406 4 times with a remainder of 50.
The next digit of our result is 4. 
Result so far: 744.0
Deduct 356 from 406 and we're left with 50.
Bring next digit (6) of the dividend behind the 50 and repeat the process: 506 / 89

Step 6:
89 can be fit into 506 5 times, resulting in a remainder of 61.
Write down 5 as next digit of the result. 
Result so far: 7445.0
If we take 445 away from 506, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 7:
When dividing 610 by 89, we get 6 with a remainder of 76.
Put 6 as the next digit of the answer. 
Result so far: 7445.6
If we subtract 534 from 610, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 8:
If we divide 760 by 89, we get 8 and a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 7445.68
The remainder is 48 after subtracting 712 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 9:
If we divide 480 by 89, we get 5 and a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 7445.685
The remainder is 35 after subtracting 445 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 10:
If we divide 350 by 89, we get 3 and a remainder of 83.
The next digit of our result is 3. 
Result so far: 7445.6853
If we take 267 away from 350, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 11:
When dividing 830 by 89, we get 9 with a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 7445.68539
Subtracting 801 from 830 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 12:
89 goes into 290 3 times with a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 7445.685393
If we take 267 away from 290, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 13:
89 goes into 230 2 times with a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 7445.6853932
Subtracting 178 from 230 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 14:
If we divide 520 by 89, we get 5 and a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 7445.68539325
Subtract 445 from 520 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

The final result is 7445.68539325 with a remainder of 7.5e-08.
