We look at the division of 685902 by 53 
The aim is to understand the frequency of 53 in 685902.

Going ahead to step 1:
53 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 53

Advancing to step 2:
53 can be fit into 68 1 times, resulting in a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 53 away from 68, we end up with 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 53

Moving on to step 3:
The number 53 fits into 155 2 times, leaving a remainder of 49.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 106 from 155, we get 49.
Fetch the next digit (9) from the dividend, attach it to 49 and continue: 499 / 53

Going ahead to step 4:
If we divide 499 by 53, we get 9 and a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 129.0
If we take 477 away from 499, we end up with 22.
Append the next digit (0) from the dividend to 22 and continue with: 220 / 53

Let's proceed to step 5:
The number 53 fits into 220 4 times, leaving a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 1294.0
Subtracting 212 from 220 leaves us with 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 53

Moving on to step 6:
The number 53 fits into 82 1 times, leaving a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 12941.0
Subtract 53 from 82 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 7:
When dividing 290 by 53, we get 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 12941.5
Deduct 265 from 290 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.

Step 8:
53 goes into 250 4 times with a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 12941.54
If we take 212 away from 250, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 9:
If we divide 380 by 53, we get 7 and a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 12941.547
Subtract 371 from 380 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 10:
53 can be fit into 90 1 times, resulting in a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 12941.5471
If we take 53 away from 90, we end up 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.

On to step 11:
53 can be fit into 370 6 times, resulting in a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 12941.54716
The remainder is 52 after subtracting 318 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 12:
53 can be fit into 520 9 times, resulting in a remainder of 43.
Write down 9 as next digit of the result. 
Result so far: 12941.547169
If we take 477 away from 520, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 13:
When dividing 430 by 53, we get 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 12941.5471698
If we subtract 424 from 430, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 14:
53 goes into 60 1 times with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 12941.54716981
If we take 53 away from 60, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final result is 12941.54716981 with a remainder of 7e-09.
