We look at the division of 71611945 by 69 
The aim is to understand the frequency of 69 in 71611945.

Step 1:
69 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 69

Let's proceed to step 2:
69 can be fit into 71 1 times, resulting in a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 69 from 71 leaves us with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 69

Let's proceed to step 3:
The number 69 fits into 26 0 times, leaving a remainder of 26.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 26, we end up with 26.
Bring next digit (1) of the dividend behind the 26 and repeat the process: 261 / 69

On to step 4:
69 can be fit into 261 3 times, resulting in a remainder of 54.
The next digit of our result is 3. 
Result so far: 103.0
Subtracting 207 from 261 leaves us with 54.
Take the next digit (1) from the dividend and append it to 54, then repeat: 541 / 69

Advancing to step 5:
69 goes into 541 7 times with a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 1037.0
The remainder is 58 after subtracting 483 from 541.
Append the next digit (9) from the dividend to 58 and continue with: 589 / 69

Moving on to step 6:
69 goes into 589 8 times with a remainder of 37.
Record the quotient 8 as the next digit in the result. 
Result so far: 10378.0
Deduct 552 from 589 and we're left with 37.
Include the next digit (4) from the dividend after 37, then repeat: 374 / 69

On to step 7:
When dividing 374 by 69, we get 5 with a remainder of 29.
The number 5 becomes the next digit in our result. 
Result so far: 103785.0
Deduct 345 from 374 and we're left with 29.
Take the next digit (5) from the dividend and append it to 29, then repeat: 295 / 69

Let's proceed to step 8:
If we divide 295 by 69, we get 4 and a remainder of 19.
The number 4 becomes the next digit in our result. 
Result so far: 1037854.0
The remainder is 19 after subtracting 276 from 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 9:
190 divided by 69 is 2 with a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 1037854.2
If we subtract 138 from 190, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 10:
The number 69 fits into 520 7 times, leaving a remainder of 37.
The next digit of our result is 7. 
Result so far: 1037854.27
The remainder is 37 after subtracting 483 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 11:
If we divide 370 by 69, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 1037854.275
Deduct 345 from 370 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 12:
250 divided by 69 is 3 with a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 1037854.2753
The remainder is 43 after subtracting 207 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 13:
When dividing 430 by 69, we get 6 with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 1037854.27536
If we subtract 414 from 430, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 14:
69 can be fit into 160 2 times, resulting in a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 1037854.275362
Subtract 138 from 160 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 15:
220 divided by 69 is 3 with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 1037854.2753623
Subtract 207 from 220 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 16:
The number 69 fits into 130 1 times, leaving a remainder of 61.
Put 1 as the next digit of the answer. 
Result so far: 1037854.27536231
Subtract 69 from 130 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

In conclusion, the division gives 1037854.27536231 with a balance of 6.1e-08.
