We look at the division of 233069 by 7 
The aim is to understand the frequency of 7 in 233069.

On to step 1:
7 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 7

Going ahead to step 2:
When dividing 23 by 7, we get 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 21 from 23 and we're left with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 7

Let's proceed to step 3:
When dividing 23 by 7, we get 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 33.0
Deduct 21 from 23 and we're left with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 7

Step 4:
If we divide 20 by 7, we get 2 and a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 332.0
If we subtract 14 from 20, we get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 7

Going ahead to step 5:
If we divide 66 by 7, we get 9 and a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 3329.0
If we subtract 63 from 66, we get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 7

Going ahead to step 6:
The number 7 fits into 39 5 times, leaving a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 33295.0
The remainder is 4 after subtracting 35 from 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 33295.5
If we take 35 away from 40, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
7 goes into 50 7 times with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 33295.57
If we subtract 49 from 50, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 33295.571
The remainder is 3 after subtracting 7 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 33295.5714
If we take 28 away from 30, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
7 goes into 20 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 33295.57142
If we take 14 away from 20, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 12:
7 goes into 60 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 33295.571428
Deduct 56 from 60 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
When dividing 40 by 7, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 33295.5714285
If we take 35 away from 40, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 14:
7 goes into 50 7 times with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 33295.57142857
The remainder is 1 after subtracting 49 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Our division results in 33295.57142857 with a remaining 1e-09.
