We look at the division of 562280 by 7 
The aim is to understand the frequency of 7 in 562280.

Step 1:
5 divided by 7 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 7

Advancing to step 2:
56 divided by 7 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 56 from 56 and we're left with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 7

Moving on to step 3:
7 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 7

Moving on to step 4:
7 goes into 22 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 803.0
The remainder is 1 after subtracting 21 from 22.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 7

Moving on to step 5:
If we divide 18 by 7, we get 2 and a remainder of 4.
The next digit of our result is 2. 
Result so far: 8032.0
Deduct 14 from 18 and we're left with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 7

Let's proceed to step 6:
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: 80325.0
Subtracting 35 from 40 leaves us 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 7:
When dividing 50 by 7, we get 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 80325.7
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.

Step 8:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 80325.71
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.

Let's proceed to step 9:
30 divided by 7 is 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 80325.714
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 10:
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: 80325.7142
Subtract 14 from 20 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.

Advancing to step 11:
60 divided by 7 is 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 80325.71428
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.

Let's proceed to step 12:
7 can be fit into 40 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 80325.714285
Subtracting 35 from 40 leaves us 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.

Advancing to step 13:
7 goes into 50 7 times with a remainder of 1.
The next digit of our result is 7. 
Result so far: 80325.7142857
Subtracting 49 from 50 leaves us 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.

Step 14:
7 goes into 10 1 times with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 80325.71428571
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.

In conclusion, the division gives 80325.71428571 with a balance of 3e-09.
