We look at the division of 261671 by 69 
The aim is to understand the frequency of 69 in 261671.

Going ahead to step 1:
69 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 69

Let's proceed to step 2:
69 can be fit into 26 0 times, resulting in a remainder of 26.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 26, we get 26.
Bring next digit (1) of the dividend behind the 26 and repeat the process: 261 / 69

Advancing to step 3:
261 divided by 69 is 3 with a remainder of 54.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 207 from 261, we get 54.
Take the next digit (6) from the dividend and append it to 54, then repeat: 546 / 69

Going ahead to step 4:
69 goes into 546 7 times with a remainder of 63.
The next digit of our result is 7. 
Result so far: 37.0
Subtract 483 from 546 to get 63.
Append the next digit (7) from the dividend to 63 and continue with: 637 / 69

Moving on to step 5:
If we divide 637 by 69, we get 9 and a remainder of 16.
The next digit of our result is 9. 
Result so far: 379.0
Deduct 621 from 637 and we're left with 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 69

Advancing to step 6:
If we divide 161 by 69, we get 2 and a remainder of 23.
The number 2 becomes the next digit in our result. 
Result so far: 3792.0
Subtracting 138 from 161 leaves us 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 7:
When dividing 230 by 69, we get 3 with a remainder of 23.
The next digit of our result is 3. 
Result so far: 3792.3
The remainder is 23 after subtracting 207 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 8:
69 can be fit into 230 3 times, resulting in a remainder of 23.
The next digit of our result is 3. 
Result so far: 3792.33
Subtract 207 from 230 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final outcome is 3792.33, with a leftover of 0.023.
