We divide 16530 by 42
The aim is to understand the frequency of 42 in 16530.

Step 1:
42 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 42

Step 2:
When dividing 16 by 42, we get 0 with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 42

Going ahead to step 3:
The number 42 fits into 165 3 times, leaving a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 39 after subtracting 126 from 165.
Include the next digit (3) from the dividend after 39, then repeat: 393 / 42

Step 4:
42 can be fit into 393 9 times, resulting in a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 39.0
Subtract 378 from 393 to get 15.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 42

Let's proceed to step 5:
If we divide 150 by 42, we get 3 and a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 393.0
Subtracting 126 from 150 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.

Step 6:
If we divide 240 by 42, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 393.5
If we subtract 210 from 240, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 7:
If we divide 300 by 42, we get 7 and a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 393.57
Subtract 294 from 300 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
When dividing 60 by 42, we get 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 393.571
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 9:
When dividing 180 by 42, we get 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 393.5714
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.

Going ahead to step 10:
The number 42 fits into 120 2 times, leaving a remainder of 36.
The next digit of our result is 2. 
Result so far: 393.57142
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.

On to step 11:
42 goes into 360 8 times with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 393.571428
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.

On to step 12:
When dividing 240 by 42, we get 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 393.5714285
Subtracting 210 from 240 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 13:
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: 393.57142857
Subtract 294 from 300 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

In conclusion, the division gives 393.57142857 with a balance of 6e-09.
