We look at the division of 42583373 by 135 
The aim is to understand the frequency of 135 in 42583373.

Going ahead to step 1:
The number 135 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 135

Step 2:
135 can be fit into 42 0 times, resulting in a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Fetch the next digit (5) from the dividend, attach it to 42 and continue: 425 / 135

Advancing to step 3:
135 goes into 425 3 times with a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 20 after subtracting 405 from 425.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 135

On to step 4:
If we divide 208 by 135, we get 1 and a remainder of 73.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Subtracting 135 from 208 leaves us with 73.
Grab the next digit (3) from the dividend, add it to 73, then carry on: 733 / 135

Moving on to step 5:
135 can be fit into 733 5 times, resulting in a remainder of 58.
The next digit of our result is 5. 
Result so far: 315.0
If we subtract 675 from 733, we get 58.
Grab the next digit (3) from the dividend, add it to 58, then carry on: 583 / 135

Going ahead to step 6:
The number 135 fits into 583 4 times, leaving a remainder of 43.
Put 4 as the next digit of the answer. 
Result so far: 3154.0
The remainder is 43 after subtracting 540 from 583.
Fetch the next digit (7) from the dividend, attach it to 43 and continue: 437 / 135

Going ahead to step 7:
437 divided by 135 is 3 with a remainder of 32.
Use 3 as the next digit of our solution. 
Result so far: 31543.0
If we take 405 away from 437, we end up with 32.
Grab the next digit (3) from the dividend, add it to 32, then carry on: 323 / 135

Step 8:
The number 135 fits into 323 2 times, leaving a remainder of 53.
The number 2 becomes the next digit in our result. 
Result so far: 315432.0
The remainder is 53 after subtracting 270 from 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 9:
135 goes into 530 3 times with a remainder of 125.
Record the quotient 3 as the next digit in the result. 
Result so far: 315432.3
If we take 405 away from 530, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 10:
If we divide 1250 by 135, we get 9 and a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 315432.39
If we take 1215 away from 1250, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 11:
135 goes into 350 2 times with a remainder of 80.
Put 2 as the next digit of the answer. 
Result so far: 315432.392
Subtracting 270 from 350 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 12:
800 divided by 135 is 5 with a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 315432.3925
If we take 675 away from 800, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 13:
The number 135 fits into 1250 9 times, leaving a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 315432.39259
Subtracting 1215 from 1250 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 14:
When dividing 350 by 135, we get 2 with a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 315432.392592
If we take 270 away from 350, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 15:
The number 135 fits into 800 5 times, leaving a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 315432.3925925
If we subtract 675 from 800, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 16:
135 can be fit into 1250 9 times, resulting in a remainder of 35.
Put 9 as the next digit of the answer. 
Result so far: 315432.39259259
If we subtract 1215 from 1250, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

In conclusion, the division gives 315432.39259259 with a balance of 3.5e-08.
