We look at the division of 584976 by 7 
The aim is to understand the frequency of 7 in 584976.

Let's proceed to step 1:
If we divide 5 by 7, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 7

Let's proceed to step 2:
7 goes into 58 8 times with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 56 from 58 and we're left with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 7

Step 3:
The number 7 fits into 24 3 times, leaving a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
If we subtract 21 from 24, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 7

Let's proceed to step 4:
When dividing 39 by 7, we get 5 with a remainder of 4.
The next digit of our result is 5. 
Result so far: 835.0
If we take 35 away from 39, we end up with 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 7

Moving on to step 5:
7 goes into 47 6 times with a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 8356.0
If we take 42 away from 47, we end up with 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 7

On to step 6:
56 divided by 7 is 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 83568.0
Subtract 56 from 56 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
0 divided by 7 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 83568.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
If we divide 0 by 7, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 83568.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 83568.0 and a remainder of 0.0.
