We look at the division of 685035 by 53 
The aim is to understand the frequency of 53 in 685035.

Let's proceed to step 1:
If we divide 6 by 53, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 53

On to step 2:
The number 53 fits into 68 1 times, leaving a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 15 after subtracting 53 from 68.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 53

On to step 3:
155 divided by 53 is 2 with a remainder of 49.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 106 from 155, we get 49.
Fetch the next digit (0) from the dividend, attach it to 49 and continue: 490 / 53

Let's proceed to step 4:
53 goes into 490 9 times with a remainder of 13.
The next digit of our result is 9. 
Result so far: 129.0
If we take 477 away from 490, we end up with 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 53

Going ahead to step 5:
The number 53 fits into 133 2 times, leaving a remainder of 27.
Put 2 as the next digit of the answer. 
Result so far: 1292.0
If we take 106 away from 133, we end up with 27.
Include the next digit (5) from the dividend after 27, then repeat: 275 / 53

On to step 6:
53 goes into 275 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 12925.0
Subtracting 265 from 275 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
When dividing 100 by 53, we get 1 with a remainder of 47.
Put 1 as the next digit of the answer. 
Result so far: 12925.1
Subtracting 53 from 100 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 8:
53 can be fit into 470 8 times, resulting in a remainder of 46.
Use 8 as the next digit of our solution. 
Result so far: 12925.18
Subtract 424 from 470 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 9:
53 can be fit into 460 8 times, resulting in a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 12925.188
Subtract 424 from 460 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 12925.188 and a remainder of 0.0036.
