We're dividing 749751 by 89 
The aim is to understand the frequency of 89 in 749751.

Let's proceed to step 1:
If we divide 7 by 89, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 89

Moving on to step 2:
When dividing 74 by 89, we get 0 with a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Bring next digit (9) of the dividend behind the 74 and repeat the process: 749 / 89

Going ahead to step 3:
89 can be fit into 749 8 times, resulting in a remainder of 37.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 712 from 749, we get 37.
Include the next digit (7) from the dividend after 37, then repeat: 377 / 89

Let's proceed to step 4:
When dividing 377 by 89, we get 4 with a remainder of 21.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
Subtracting 356 from 377 leaves us with 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 89

On to step 5:
If we divide 215 by 89, we get 2 and a remainder of 37.
The number 2 becomes the next digit in our result. 
Result so far: 842.0
Deduct 178 from 215 and we're left with 37.
Bring next digit (1) of the dividend behind the 37 and repeat the process: 371 / 89

Let's proceed to step 6:
When dividing 371 by 89, we get 4 with a remainder of 15.
Record the quotient 4 as the next digit in the result. 
Result so far: 8424.0
The remainder is 15 after subtracting 356 from 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
When dividing 150 by 89, we get 1 with a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 8424.1
If we take 89 away from 150, 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.

Let's proceed to step 8:
89 goes into 610 6 times with a remainder of 76.
The next digit of our result is 6. 
Result so far: 8424.16
Subtracting 534 from 610 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 9:
The number 89 fits into 760 8 times, leaving a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 8424.168
Subtract 712 from 760 to get 48.
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 10:
89 goes into 480 5 times with a remainder of 35.
The next digit of our result is 5. 
Result so far: 8424.1685
If we subtract 445 from 480, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 11:
89 can be fit into 350 3 times, resulting in a remainder of 83.
The number 3 becomes the next digit in our result. 
Result so far: 8424.16853
The remainder is 83 after subtracting 267 from 350.
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 12:
When dividing 830 by 89, we get 9 with a remainder of 29.
The next digit of our result is 9. 
Result so far: 8424.168539
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.

On to step 13:
89 can be fit into 290 3 times, resulting in a remainder of 23.
The next digit of our result is 3. 
Result so far: 8424.1685393
Deduct 267 from 290 and we're left 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.

Going ahead to step 14:
230 divided by 89 is 2 with a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 8424.16853932
The remainder is 52 after subtracting 178 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

In conclusion, the division gives 8424.16853932 with a balance of 5.2e-08.
