5541 ÷ 42 
The aim is to understand the frequency of 42 in 5541.

Advancing to step 1:
42 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 42

Let's proceed to step 2:
The number 42 fits into 55 1 times, leaving a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 42 away from 55, we end up with 13.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 42

Going ahead to step 3:
42 goes into 134 3 times with a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 126 from 134 leaves us with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 42

Let's proceed to step 4:
42 can be fit into 81 1 times, resulting in a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 131.0
If we subtract 42 from 81, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 5:
42 can be fit into 390 9 times, resulting in a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 131.9
Subtracting 378 from 390 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 6:
If we divide 120 by 42, we get 2 and a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 131.92
The remainder is 36 after subtracting 84 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 7:
360 divided by 42 is 8 with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 131.928
Subtracting 336 from 360 leaves us 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.

Moving on to step 8:
42 can be fit into 240 5 times, resulting in a remainder of 30.
The next digit of our result is 5. 
Result so far: 131.9285
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.

Going ahead to step 9:
The number 42 fits into 300 7 times, leaving a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 131.92857
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.

Going ahead to step 10:
42 goes into 60 1 times with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 131.928571
If we take 42 away from 60, we end up 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.

Let's proceed to step 11:
The number 42 fits into 180 4 times, leaving a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 131.9285714
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
120 divided by 42 is 2 with a remainder of 36.
The next digit of our result is 2. 
Result so far: 131.92857142
If we take 84 away from 120, we end up 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.

After the division, we end up with 131.92857142 and a remainder of 3.6e-08.
