We're dividing 392022 by 7 
The aim is to understand the frequency of 7 in 392022.

Going ahead to step 1:
3 divided by 7 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 7

Let's proceed to step 2:
7 can be fit into 39 5 times, resulting in a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 35 from 39, we get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 7

Let's proceed to step 3:
If we divide 42 by 7, we get 6 and a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 56.0
If we subtract 42 from 42, we get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 7

Advancing to step 4:
7 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 560.0
Subtract 0 from 0 to get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 7

Let's proceed to step 5:
2 divided by 7 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 5600.0
Subtract 0 from 2 to get 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 7

Let's proceed to step 6:
If we divide 22 by 7, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 56003.0
The remainder is 1 after subtracting 21 from 22.
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 7:
The number 7 fits into 10 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 56003.1
Subtract 7 from 10 to get 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 8:
30 divided by 7 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 56003.14
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.

Step 9:
20 divided by 7 is 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 56003.142
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 10:
7 can be fit into 60 8 times, resulting in a remainder of 4.
The next digit of our result is 8. 
Result so far: 56003.1428
If we take 56 away from 60, we end up 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 11:
When dividing 40 by 7, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 56003.14285
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.

On to step 12:
When dividing 50 by 7, we get 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 56003.142857
Subtract 49 from 50 to 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.

Going ahead to step 13:
When dividing 10 by 7, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 56003.1428571
If we take 7 away from 10, 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.

On to step 14:
7 goes into 30 4 times with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 56003.14285714
Subtracting 28 from 30 leaves us 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.

The final result is 56003.14285714 with a remainder of 2e-09.
