Let's divide 181326 by 42
The aim is to understand the frequency of 42 in 181326.

Moving on to step 1:
The number 42 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 42

Step 2:
When dividing 18 by 42, we get 0 with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 42

Step 3:
When dividing 181 by 42, we get 4 with a remainder of 13.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 168 from 181 and we're left with 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 42

Going ahead to step 4:
When dividing 133 by 42, we get 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Deduct 126 from 133 and we're left with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 42

Step 5:
42 goes into 72 1 times with a remainder of 30.
The next digit of our result is 1. 
Result so far: 431.0
Subtracting 42 from 72 leaves us with 30.
Include the next digit (6) from the dividend after 30, then repeat: 306 / 42

Moving on to step 6:
42 can be fit into 306 7 times, resulting in a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 4317.0
Subtracting 294 from 306 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 7:
42 can be fit into 120 2 times, resulting in a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 4317.2
Subtracting 84 from 120 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 8:
The number 42 fits into 360 8 times, leaving a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 4317.28
If we take 336 away from 360, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
240 divided by 42 is 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 4317.285
The remainder is 30 after subtracting 210 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
42 can be fit into 300 7 times, resulting in a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 4317.2857
The remainder is 6 after subtracting 294 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 11:
42 goes into 60 1 times with a remainder of 18.
The next digit of our result is 1. 
Result so far: 4317.28571
Subtracting 42 from 60 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 12:
180 divided by 42 is 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 4317.285714
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 13:
The number 42 fits into 120 2 times, leaving a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 4317.2857142
Subtracting 84 from 120 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 14:
When dividing 360 by 42, we get 8 with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 4317.28571428
Subtract 336 from 360 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 4317.28571428 with a remaining 2.4e-08.
