We look at the division of 652917 by 7 
The aim is to understand the frequency of 7 in 652917.

Moving on to step 1:
When dividing 6 by 7, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 7

Moving on to step 2:
65 divided by 7 is 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 63 from 65 to get 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 7

Advancing to step 3:
If we divide 22 by 7, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 93.0
If we take 21 away from 22, we end up with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 7

Going ahead to step 4:
7 can be fit into 19 2 times, resulting in a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 932.0
Subtract 14 from 19 to get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 7

Advancing to step 5:
When dividing 51 by 7, we get 7 with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 9327.0
The remainder is 2 after subtracting 49 from 51.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 7

On to step 6:
If we divide 27 by 7, we get 3 and a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 93273.0
Subtract 21 from 27 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
60 divided by 7 is 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 93273.8
Subtract 56 from 60 to 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 8:
7 goes into 40 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 93273.85
Subtract 35 from 40 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
7 can be fit into 50 7 times, resulting in a remainder of 1.
The next digit of our result is 7. 
Result so far: 93273.857
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.

Let's proceed to step 10:
7 can be fit into 10 1 times, resulting in a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 93273.8571
Subtracting 7 from 10 leaves us 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.

Advancing to step 11:
If we divide 30 by 7, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 93273.85714
Deduct 28 from 30 and we're left 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.

Let's proceed to step 12:
If we divide 20 by 7, we get 2 and a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 93273.857142
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 13:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 93273.8571428
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.

Advancing to step 14:
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: 93273.85714285
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.

The final result is 93273.85714285 with a remainder of 5e-09.
