307029 divided by 7 
The aim is to understand the frequency of 7 in 307029.

Going ahead to step 1:
When dividing 3 by 7, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 7

Let's proceed to step 2:
7 goes into 30 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 28 away from 30, we end up with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 7

Moving on to step 3:
The number 7 fits into 27 3 times, leaving a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 43.0
Deduct 21 from 27 and we're left with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 7

Let's proceed to step 4:
7 goes into 60 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 438.0
The remainder is 4 after subtracting 56 from 60.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 7

Step 5:
7 goes into 42 6 times with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 4386.0
Subtract 42 from 42 to get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 7

Step 6:
7 can be fit into 9 1 times, resulting in a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 43861.0
If we take 7 away from 9, 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.

Advancing to step 7:
7 goes into 20 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 43861.2
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.

Advancing to step 8:
60 divided by 7 is 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 43861.28
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.

Step 9:
7 goes into 40 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 43861.285
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 10:
The number 7 fits into 50 7 times, leaving a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 43861.2857
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.

Moving on to step 11:
If we divide 10 by 7, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 43861.28571
Deduct 7 from 10 and we're left 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.

Moving on to step 12:
If we divide 30 by 7, we get 4 and a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 43861.285714
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.

Going ahead to step 13:
7 goes into 20 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 43861.2857142
Subtracting 14 from 20 leaves us 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.

On to step 14:
If we divide 60 by 7, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 43861.28571428
Subtracting 56 from 60 leaves us 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.

The quotient of the division is 43861.28571428, and the remainder is 4e-09.
