We look at the division of 665349 by 69 
The aim is to understand the frequency of 69 in 665349.

Moving on to step 1:
If we divide 6 by 69, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 69

Going ahead to step 2:
If we divide 66 by 69, we get 0 and a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Grab the next digit (5) from the dividend, add it to 66, then carry on: 665 / 69

Advancing to step 3:
69 can be fit into 665 9 times, resulting in a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 621 away from 665, we end up with 44.
Bring next digit (3) of the dividend behind the 44 and repeat the process: 443 / 69

Let's proceed to step 4:
69 goes into 443 6 times with a remainder of 29.
Write down 6 as next digit of the result. 
Result so far: 96.0
If we subtract 414 from 443, we get 29.
Include the next digit (4) from the dividend after 29, then repeat: 294 / 69

Step 5:
69 goes into 294 4 times with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 964.0
Deduct 276 from 294 and we're left with 18.
Take the next digit (9) from the dividend and append it to 18, then repeat: 189 / 69

On to step 6:
The number 69 fits into 189 2 times, leaving a remainder of 51.
The number 2 becomes the next digit in our result. 
Result so far: 9642.0
The remainder is 51 after subtracting 138 from 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 7:
When dividing 510 by 69, we get 7 with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 9642.7
If we subtract 483 from 510, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 8:
When dividing 270 by 69, we get 3 with a remainder of 63.
The number 3 becomes the next digit in our result. 
Result so far: 9642.73
The remainder is 63 after subtracting 207 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 9:
If we divide 630 by 69, we get 9 and a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 9642.739
If we take 621 away from 630, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 10:
When dividing 90 by 69, we get 1 with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 9642.7391
If we take 69 away from 90, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 11:
210 divided by 69 is 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 9642.73913
Subtract 207 from 210 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 12:
69 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 9642.73913
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 13:
The number 69 fits into 300 4 times, leaving a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 9642.7391304
Subtract 276 from 300 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 14:
69 can be fit into 240 3 times, resulting in a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 9642.73913043
Deduct 207 from 240 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

After the division, we end up with 9642.73913043 and a remainder of 3.3e-08.
