We're dividing 394357 by 69 
The aim is to understand the frequency of 69 in 394357.

Let's proceed to step 1:
3 divided by 69 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 69

Advancing to step 2:
39 divided by 69 is 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Take the next digit (4) from the dividend and append it to 39, then repeat: 394 / 69

Advancing to step 3:
If we divide 394 by 69, we get 5 and a remainder of 49.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 345 from 394 and we're left with 49.
Fetch the next digit (3) from the dividend, attach it to 49 and continue: 493 / 69

Going ahead to step 4:
When dividing 493 by 69, we get 7 with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
If we subtract 483 from 493, we get 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 69

Step 5:
If we divide 105 by 69, we get 1 and a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 571.0
Subtracting 69 from 105 leaves us with 36.
Take the next digit (7) from the dividend and append it to 36, then repeat: 367 / 69

Advancing to step 6:
69 goes into 367 5 times with a remainder of 22.
Put 5 as the next digit of the answer. 
Result so far: 5715.0
If we take 345 away from 367, we end up 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.

Advancing to step 7:
The number 69 fits into 220 3 times, leaving a remainder of 13.
The next digit of our result is 3. 
Result so far: 5715.3
The remainder is 13 after subtracting 207 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 8:
130 divided by 69 is 1 with a remainder of 61.
Record the quotient 1 as the next digit in the result. 
Result so far: 5715.31
The remainder is 61 after subtracting 69 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 9:
69 can be fit into 610 8 times, resulting in a remainder of 58.
Record the quotient 8 as the next digit in the result. 
Result so far: 5715.318
Deduct 552 from 610 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 10:
When dividing 580 by 69, we get 8 with a remainder of 28.
The next digit of our result is 8. 
Result so far: 5715.3188
The remainder is 28 after subtracting 552 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 5715.3188 and a remainder of 0.00028.
