499565 ÷ 7 
The aim is to understand the frequency of 7 in 499565.

On to step 1:
7 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 7

Advancing to step 2:
49 divided by 7 is 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 49 from 49 and we're left with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 7

On to step 3:
If we divide 9 by 7, we get 1 and a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 71.0
If we subtract 7 from 9, we get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 7

Going ahead to step 4:
25 divided by 7 is 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 713.0
If we take 21 away from 25, we end up with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 7

Going ahead to step 5:
If we divide 46 by 7, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 7136.0
Subtracting 42 from 46 leaves us with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 7

Let's proceed to step 6:
When dividing 45 by 7, we get 6 with a remainder of 3.
The next digit of our result is 6. 
Result so far: 71366.0
If we take 42 away from 45, 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 7:
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: 71366.4
If we subtract 28 from 30, we 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 8:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 71366.42
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.

On to step 9:
If we divide 60 by 7, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 71366.428
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.

Step 10:
40 divided by 7 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 71366.4285
Deduct 35 from 40 and we're left 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 11:
When dividing 50 by 7, we get 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 71366.42857
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.

Advancing to step 12:
The number 7 fits into 10 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 71366.428571
If we subtract 7 from 10, we 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.

On to step 13:
7 can be fit into 30 4 times, resulting in a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 71366.4285714
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.

Step 14:
20 divided by 7 is 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 71366.42857142
The remainder is 6 after subtracting 14 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The quotient of the division is 71366.42857142, and the remainder is 6e-09.
