518914 divided by 69 
The aim is to understand the frequency of 69 in 518914.

Moving on to step 1:
If we divide 5 by 69, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 69

Advancing to step 2:
The number 69 fits into 51 0 times, leaving a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Include the next digit (8) from the dividend after 51, then repeat: 518 / 69

Advancing to step 3:
The number 69 fits into 518 7 times, leaving a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 483 away from 518, we end up with 35.
Grab the next digit (9) from the dividend, add it to 35, then carry on: 359 / 69

Moving on to step 4:
69 goes into 359 5 times with a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 75.0
The remainder is 14 after subtracting 345 from 359.
Append the next digit (1) from the dividend to 14 and continue with: 141 / 69

Moving on to step 5:
The number 69 fits into 141 2 times, leaving a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 752.0
Subtract 138 from 141 to get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 69

Advancing to step 6:
34 divided by 69 is 0 with a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 7520.0
Subtract 0 from 34 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 7:
If we divide 340 by 69, we get 4 and a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 7520.4
Deduct 276 from 340 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 8:
69 can be fit into 640 9 times, resulting in a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 7520.49
Subtract 621 from 640 to get 19.
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:
The number 69 fits into 190 2 times, leaving a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 7520.492
If we take 138 away from 190, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 10:
520 divided by 69 is 7 with a remainder of 37.
The next digit of our result is 7. 
Result so far: 7520.4927
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.

On to step 11:
If we divide 370 by 69, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 7520.49275
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.

Let's proceed to step 12:
250 divided by 69 is 3 with a remainder of 43.
The next digit of our result is 3. 
Result so far: 7520.492753
Subtracting 207 from 250 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 13:
If we divide 430 by 69, we get 6 and a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 7520.4927536
Subtracting 414 from 430 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 14:
The number 69 fits into 160 2 times, leaving a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 7520.49275362
Deduct 138 from 160 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 7520.49275362, with a leftover of 2.2e-08.
