We look at the division of 135419 by 53 
The aim is to understand the frequency of 53 in 135419.

Let's proceed to step 1:
53 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 53

Let's proceed to step 2:
53 can be fit into 13 0 times, resulting in a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 53

Let's proceed to step 3:
If we divide 135 by 53, we get 2 and a remainder of 29.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 29 after subtracting 106 from 135.
Include the next digit (4) from the dividend after 29, then repeat: 294 / 53

Advancing to step 4:
The number 53 fits into 294 5 times, leaving a remainder of 29.
Write down 5 as next digit of the result. 
Result so far: 25.0
If we take 265 away from 294, we end up with 29.
Bring next digit (1) of the dividend behind the 29 and repeat the process: 291 / 53

Advancing to step 5:
53 goes into 291 5 times with a remainder of 26.
The next digit of our result is 5. 
Result so far: 255.0
The remainder is 26 after subtracting 265 from 291.
Grab the next digit (9) from the dividend, add it to 26, then carry on: 269 / 53

Moving on to step 6:
53 can be fit into 269 5 times, resulting in a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 2555.0
Deduct 265 from 269 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
When dividing 40 by 53, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 2555.0
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 8:
If we divide 400 by 53, we get 7 and a remainder of 29.
The next digit of our result is 7. 
Result so far: 2555.07
If we take 371 away from 400, we end up with 29.
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 9:
The number 53 fits into 290 5 times, leaving a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 2555.075
If we take 265 away from 290, we end up 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 10:
When dividing 250 by 53, we get 4 with a remainder of 38.
The next digit of our result is 4. 
Result so far: 2555.0754
Deduct 212 from 250 and we're left 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 11:
When dividing 380 by 53, we get 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 2555.07547
Subtracting 371 from 380 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 12:
53 can be fit into 90 1 times, resulting in a remainder of 37.
The next digit of our result is 1. 
Result so far: 2555.075471
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.

Moving on to step 13:
If we divide 370 by 53, we get 6 and a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 2555.0754716
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.

Moving on to step 14:
If we divide 520 by 53, we get 9 and a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 2555.07547169
If we subtract 477 from 520, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

In conclusion, the division gives 2555.07547169 with a balance of 4.3e-08.
