689695 divided by 89 
The aim is to understand the frequency of 89 in 689695.

On to step 1:
6 divided by 89 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 89

Moving on to step 2:
89 can be fit into 68 0 times, resulting in a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Append the next digit (9) from the dividend to 68 and continue with: 689 / 89

Going ahead to step 3:
When dividing 689 by 89, we get 7 with a remainder of 66.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 623 away from 689, we end up with 66.
Bring next digit (6) of the dividend behind the 66 and repeat the process: 666 / 89

Let's proceed to step 4:
When dividing 666 by 89, we get 7 with a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 77.0
The remainder is 43 after subtracting 623 from 666.
Bring next digit (9) of the dividend behind the 43 and repeat the process: 439 / 89

Step 5:
If we divide 439 by 89, we get 4 and a remainder of 83.
The next digit of our result is 4. 
Result so far: 774.0
Subtract 356 from 439 to get 83.
Take the next digit (5) from the dividend and append it to 83, then repeat: 835 / 89

Moving on to step 6:
89 can be fit into 835 9 times, resulting in a remainder of 34.
Write down 9 as next digit of the result. 
Result so far: 7749.0
Deduct 801 from 835 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 7:
89 can be fit into 340 3 times, resulting in a remainder of 73.
Use 3 as the next digit of our solution. 
Result so far: 7749.3
If we subtract 267 from 340, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 8:
If we divide 730 by 89, we get 8 and a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 7749.38
Subtract 712 from 730 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 9:
180 divided by 89 is 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 7749.382
If we subtract 178 from 180, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
If we divide 20 by 89, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 7749.382
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
When dividing 200 by 89, we get 2 with a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 7749.38202
Subtract 178 from 200 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 12:
The number 89 fits into 220 2 times, leaving a remainder of 42.
The next digit of our result is 2. 
Result so far: 7749.382022
If we subtract 178 from 220, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

In conclusion, the division gives 7749.382022 with a balance of 4.2e-06.
