Let's divide 69139161 by 689
The aim is to understand the frequency of 689 in 69139161.

Step 1:
689 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 689

Going ahead to step 2:
689 goes into 69 0 times with a remainder of 69.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 69 after subtracting 0 from 69.
Grab the next digit (1) from the dividend, add it to 69, then carry on: 691 / 689

Let's proceed to step 3:
691 divided by 689 is 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 689 away from 691, we end up with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 689

Step 4:
When dividing 23 by 689, we get 0 with a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 23 to get 23.
Take the next digit (9) from the dividend and append it to 23, then repeat: 239 / 689

Let's proceed to step 5:
If we divide 239 by 689, we get 0 and a remainder of 239.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
Deduct 0 from 239 and we're left with 239.
Include the next digit (1) from the dividend after 239, then repeat: 2391 / 689

Moving on to step 6:
When dividing 2391 by 689, we get 3 with a remainder of 324.
The next digit of our result is 3. 
Result so far: 1003.0
The remainder is 324 after subtracting 2067 from 2391.
Include the next digit (6) from the dividend after 324, then repeat: 3246 / 689

Moving on to step 7:
3246 divided by 689 is 4 with a remainder of 490.
Put 4 as the next digit of the answer. 
Result so far: 10034.0
If we subtract 2756 from 3246, we get 490.
Grab the next digit (1) from the dividend, add it to 490, then carry on: 4901 / 689

Going ahead to step 8:
689 can be fit into 4901 7 times, resulting in a remainder of 78.
Use 7 as the next digit of our solution. 
Result so far: 100347.0
The remainder is 78 after subtracting 4823 from 4901.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 9:
780 divided by 689 is 1 with a remainder of 91.
The number 1 becomes the next digit in our result. 
Result so far: 100347.1
If we take 689 away from 780, we end up with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

On to step 10:
If we divide 910 by 689, we get 1 and a remainder of 221.
Write down 1 as next digit of the result. 
Result so far: 100347.11
Subtract 689 from 910 to get 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

The quotient of the division is 100347.11, and the remainder is 0.221.
