We divide 135259 by 42
The aim is to understand the frequency of 42 in 135259.

Going ahead to step 1:
When dividing 1 by 42, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 42

Moving on to step 2:
If we divide 13 by 42, we get 0 and a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 42

On to step 3:
When dividing 135 by 42, we get 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 126 away from 135, we end up with 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 42

Advancing to step 4:
42 goes into 92 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 32.0
Subtracting 84 from 92 leaves us with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 42

Advancing to step 5:
When dividing 85 by 42, we get 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 322.0
Deduct 84 from 85 and we're left with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 42

Going ahead to step 6:
42 can be fit into 19 0 times, resulting in a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 3220.0
The remainder is 19 after subtracting 0 from 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
190 divided by 42 is 4 with a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 3220.4
Subtract 168 from 190 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 8:
220 divided by 42 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 3220.45
Deduct 210 from 220 and we're left 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.

On to step 9:
42 goes into 100 2 times with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 3220.452
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
If we divide 160 by 42, we get 3 and a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 3220.4523
Deduct 126 from 160 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 11:
When dividing 340 by 42, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 3220.45238
If we take 336 away from 340, we end up 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.

Step 12:
42 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 3220.45238
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
When dividing 400 by 42, we get 9 with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 3220.4523809
Subtract 378 from 400 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 14:
42 can be fit into 220 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 3220.45238095
Subtracting 210 from 220 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.

The final result is 3220.45238095 with a remainder of 1e-08.
