We look at the division of 789817 by 53 
The aim is to understand the frequency of 53 in 789817.

Going ahead to step 1:
When dividing 7 by 53, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 53

On to step 2:
53 goes into 78 1 times with a remainder of 25.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 53 from 78 leaves us with 25.
Grab the next digit (9) from the dividend, add it to 25, then carry on: 259 / 53

Step 3:
259 divided by 53 is 4 with a remainder of 47.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we take 212 away from 259, we end up with 47.
Append the next digit (8) from the dividend to 47 and continue with: 478 / 53

Step 4:
478 divided by 53 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 149.0
Subtract 477 from 478 to get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 53

Step 5:
The number 53 fits into 11 0 times, leaving a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 1490.0
If we take 0 away from 11, we end up with 11.
Include the next digit (7) from the dividend after 11, then repeat: 117 / 53

Let's proceed to step 6:
117 divided by 53 is 2 with a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 14902.0
If we take 106 away from 117, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
The number 53 fits into 110 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 14902.2
The remainder is 4 after subtracting 106 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
The number 53 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 14902.2
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
400 divided by 53 is 7 with a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 14902.207
The remainder is 29 after subtracting 371 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 10:
53 goes into 290 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 14902.2075
Subtracting 265 from 290 leaves us 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.

Going ahead to step 11:
53 goes into 250 4 times with a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 14902.20754
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.

Advancing to step 12:
The number 53 fits into 380 7 times, leaving a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 14902.207547
The remainder is 9 after subtracting 371 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 13:
When dividing 90 by 53, we get 1 with a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 14902.2075471
The remainder is 37 after subtracting 53 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 14:
53 goes into 370 6 times with a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 14902.20754716
If we subtract 318 from 370, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Our division results in 14902.20754716 with a remaining 5.2e-08.
