300908 ÷ 42 
The aim is to understand the frequency of 42 in 300908.

On to step 1:
42 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 42

Let's proceed to step 2:
The number 42 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Take the next digit (0) from the dividend and append it to 30, then repeat: 300 / 42

On to step 3:
The number 42 fits into 300 7 times, leaving a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 294 from 300 leaves us with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 42

Moving on to step 4:
If we divide 69 by 42, we get 1 and a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 71.0
Subtracting 42 from 69 leaves us with 27.
Append the next digit (0) from the dividend to 27 and continue with: 270 / 42

Step 5:
When dividing 270 by 42, we get 6 with a remainder of 18.
The next digit of our result is 6. 
Result so far: 716.0
Deduct 252 from 270 and we're left with 18.
Fetch the next digit (8) from the dividend, attach it to 18 and continue: 188 / 42

Let's proceed to step 6:
188 divided by 42 is 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 7164.0
If we take 168 away from 188, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
When dividing 200 by 42, we get 4 with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 7164.4
Subtract 168 from 200 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 8:
When dividing 320 by 42, we get 7 with a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 7164.47
If we subtract 294 from 320, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 9:
The number 42 fits into 260 6 times, leaving a remainder of 8.
The next digit of our result is 6. 
Result so far: 7164.476
If we subtract 252 from 260, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
42 can be fit into 80 1 times, resulting in a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 7164.4761
If we subtract 42 from 80, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 11:
When dividing 380 by 42, we get 9 with a remainder of 2.
The next digit of our result is 9. 
Result so far: 7164.47619
If we subtract 378 from 380, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 12:
42 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 7164.47619
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
The number 42 fits into 200 4 times, leaving a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 7164.4761904
Subtract 168 from 200 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 14:
320 divided by 42 is 7 with a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 7164.47619047
The remainder is 26 after subtracting 294 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Our division results in 7164.47619047 with a remaining 2.6e-08.
