We look at the division of 522847 by 75 
The aim is to understand the frequency of 75 in 522847.

On to step 1:
The number 75 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 75

Going ahead to step 2:
52 divided by 75 is 0 with a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Take the next digit (2) from the dividend and append it to 52, then repeat: 522 / 75

On to step 3:
When dividing 522 by 75, we get 6 with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 450 away from 522, we end up with 72.
Bring next digit (8) of the dividend behind the 72 and repeat the process: 728 / 75

Advancing to step 4:
75 goes into 728 9 times with a remainder of 53.
Write down 9 as next digit of the result. 
Result so far: 69.0
Subtract 675 from 728 to get 53.
Append the next digit (4) from the dividend to 53 and continue with: 534 / 75

Going ahead to step 5:
When dividing 534 by 75, we get 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 697.0
Deduct 525 from 534 and we're left with 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 75

Let's proceed to step 6:
When dividing 97 by 75, we get 1 with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 6971.0
The remainder is 22 after subtracting 75 from 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
The number 75 fits into 220 2 times, leaving a remainder of 70.
Use 2 as the next digit of our solution. 
Result so far: 6971.2
If we take 150 away from 220, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 8:
75 can be fit into 700 9 times, resulting in a remainder of 25.
Write down 9 as next digit of the result. 
Result so far: 6971.29
If we subtract 675 from 700, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
When dividing 250 by 75, we get 3 with a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 6971.293
The remainder is 25 after subtracting 225 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
250 divided by 75 is 3 with a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 6971.2933
Deduct 225 from 250 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The quotient of the division is 6971.2933, and the remainder is 0.00025.
