566207 ÷ 7 
The aim is to understand the frequency of 7 in 566207.

Moving on to 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
Subtract 0 from 5 to get 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 7

Moving on to step 2:
When dividing 56 by 7, we get 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 0 after subtracting 56 from 56.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 7

Step 3:
When dividing 6 by 7, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 80.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 7

Going ahead to step 4:
When dividing 62 by 7, we get 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 808.0
The remainder is 6 after subtracting 56 from 62.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 7

On to step 5:
When dividing 60 by 7, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 8088.0
If we take 56 away from 60, we end up with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 7

Step 6:
47 divided by 7 is 6 with a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 80886.0
If we take 42 away from 47, 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.

Moving on to step 7:
7 goes into 50 7 times with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 80886.7
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.

Let's proceed to step 8:
7 goes into 10 1 times with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 80886.71
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.

On to step 9:
7 goes into 30 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 80886.714
The remainder is 2 after subtracting 28 from 30.
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 10:
The number 7 fits into 20 2 times, leaving a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 80886.7142
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.

Going ahead to step 11:
7 goes into 60 8 times with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 80886.71428
The remainder is 4 after subtracting 56 from 60.
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 number 5 becomes the next digit in our result. 
Result so far: 80886.714285
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.

On to step 13:
7 goes into 50 7 times with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 80886.7142857
If we take 49 away from 50, we end up 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.

Moving on to step 14:
10 divided by 7 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 80886.71428571
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.

The final result is 80886.71428571 with a remainder of 3e-09.
