Let's divide 330067 by 7
The aim is to understand the frequency of 7 in 330067.

Going ahead to step 1:
The number 7 fits into 3 0 times, leaving 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.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 7

Step 2:
The number 7 fits into 33 4 times, leaving a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 28 from 33 leaves us with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 7

Advancing to step 3:
The number 7 fits into 50 7 times, leaving a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 47.0
Subtracting 49 from 50 leaves us with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 7

Advancing to step 4:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 471.0
If we subtract 7 from 10, we get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 7

Going ahead to step 5:
7 goes into 36 5 times with a remainder of 1.
The next digit of our result is 5. 
Result so far: 4715.0
If we take 35 away from 36, we end up with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 7

Advancing to step 6:
If we divide 17 by 7, we get 2 and a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 47152.0
If we take 14 away from 17, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
7 goes into 30 4 times with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 47152.4
Subtract 28 from 30 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
7 goes into 20 2 times with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 47152.42
Deduct 14 from 20 and we're left 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.

Step 9:
7 goes into 60 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 47152.428
If we subtract 56 from 60, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
40 divided by 7 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 47152.4285
The remainder is 5 after subtracting 35 from 40.
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 11:
When dividing 50 by 7, we get 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 47152.42857
Deduct 49 from 50 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 12:
10 divided by 7 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 47152.428571
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 13:
30 divided by 7 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 47152.4285714
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 14:
7 goes into 20 2 times with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 47152.42857142
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.

Our division results in 47152.42857142 with a remaining 6e-09.
