We look at the division of 478385 by 52 
The aim is to understand the frequency of 52 in 478385.

On to step 1:
When dividing 4 by 52, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 52

On to step 2:
52 can be fit into 47 0 times, resulting in a remainder of 47.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 47 and we're left with 47.
Fetch the next digit (8) from the dividend, attach it to 47 and continue: 478 / 52

Going ahead to step 3:
When dividing 478 by 52, we get 9 with a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 468 from 478 leaves us with 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 52

On to step 4:
If we divide 103 by 52, we get 1 and a remainder of 51.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
The remainder is 51 after subtracting 52 from 103.
Take the next digit (8) from the dividend and append it to 51, then repeat: 518 / 52

Moving on to step 5:
The number 52 fits into 518 9 times, leaving a remainder of 50.
The number 9 becomes the next digit in our result. 
Result so far: 919.0
Subtract 468 from 518 to get 50.
Fetch the next digit (5) from the dividend, attach it to 50 and continue: 505 / 52

Going ahead to step 6:
505 divided by 52 is 9 with a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 9199.0
Deduct 468 from 505 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 7:
If we divide 370 by 52, we get 7 and a remainder of 6.
The next digit of our result is 7. 
Result so far: 9199.7
Deduct 364 from 370 and we're left 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.

Moving on to step 8:
When dividing 60 by 52, we get 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 9199.71
If we subtract 52 from 60, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
80 divided by 52 is 1 with a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 9199.711
Subtracting 52 from 80 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 9199.711 and a remainder of 0.0028.
