We're dividing 582575 by 7 
The aim is to understand the frequency of 7 in 582575.

Let's proceed to step 1:
7 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 7

Going ahead to step 2:
The number 7 fits into 58 8 times, leaving a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 56 from 58 to get 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 7

Going ahead to step 3:
The number 7 fits into 22 3 times, leaving a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 83.0
If we take 21 away from 22, we end up with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 7

Moving on to step 4:
7 can be fit into 15 2 times, resulting in a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 832.0
If we subtract 14 from 15, we get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 7

Going ahead to step 5:
If we divide 17 by 7, we get 2 and a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 8322.0
The remainder is 3 after subtracting 14 from 17.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 7

Step 6:
The number 7 fits into 35 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 83225.0
Subtract 35 from 35 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.

Advancing to step 7:
0 divided by 7 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 83225.0
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.

On to step 8:
7 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 83225.0
Subtract 0 from 0 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.

After the division, we end up with 83225.0 and a remainder of 0.0.
