Let's divide 14681521 by 42
The aim is to understand the frequency of 42 in 14681521.

Step 1:
1 divided by 42 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 42

Let's proceed to step 2:
If we divide 14 by 42, we get 0 and a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Bring next digit (6) of the dividend behind the 14 and repeat the process: 146 / 42

Step 3:
The number 42 fits into 146 3 times, leaving a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 126 from 146, we get 20.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 42

On to step 4:
42 goes into 208 4 times with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 34.0
Subtracting 168 from 208 leaves us with 40.
Include the next digit (1) from the dividend after 40, then repeat: 401 / 42

Let's proceed to step 5:
42 can be fit into 401 9 times, resulting in a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 349.0
The remainder is 23 after subtracting 378 from 401.
Include the next digit (5) from the dividend after 23, then repeat: 235 / 42

On to step 6:
42 can be fit into 235 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 3495.0
If we take 210 away from 235, we end up with 25.
Include the next digit (2) from the dividend after 25, then repeat: 252 / 42

Going ahead to step 7:
42 can be fit into 252 6 times, resulting in a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 34956.0
If we subtract 252 from 252, we get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 42

Advancing to step 8:
42 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 349560.0
The remainder is 1 after subtracting 0 from 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
When dividing 10 by 42, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 349560.0
Deduct 0 from 10 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.

Let's proceed to step 10:
42 can be fit into 100 2 times, resulting in a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 349560.02
Deduct 84 from 100 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
If we divide 160 by 42, we get 3 and a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 349560.023
The remainder is 34 after subtracting 126 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 12:
42 goes into 340 8 times with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 349560.0238
If we subtract 336 from 340, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
If we divide 40 by 42, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 349560.0238
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 14:
The number 42 fits into 400 9 times, leaving a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 349560.023809
If we subtract 378 from 400, we 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.

Step 15:
When dividing 220 by 42, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 349560.0238095
If we take 210 away from 220, we end up 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.

Let's proceed to step 16:
100 divided by 42 is 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 349560.02380952
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 349560.02380952 with a balance of 1.6e-08.
