91469 ÷ 42 
The aim is to understand the frequency of 42 in 91469.

On to step 1:
The number 42 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 42

Moving on to step 2:
42 goes into 91 2 times with a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 84 from 91 leaves us with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 42

Let's proceed to step 3:
When dividing 74 by 42, we get 1 with a remainder of 32.
The next digit of our result is 1. 
Result so far: 21.0
If we take 42 away from 74, we end up with 32.
Bring next digit (6) of the dividend behind the 32 and repeat the process: 326 / 42

Advancing to step 4:
42 can be fit into 326 7 times, resulting in a remainder of 32.
The next digit of our result is 7. 
Result so far: 217.0
Deduct 294 from 326 and we're left with 32.
Fetch the next digit (9) from the dividend, attach it to 32 and continue: 329 / 42

Advancing to step 5:
When dividing 329 by 42, we get 7 with a remainder of 35.
The next digit of our result is 7. 
Result so far: 2177.0
If we take 294 away from 329, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 6:
42 goes into 350 8 times with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 2177.8
Subtract 336 from 350 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
If we divide 140 by 42, we get 3 and a remainder of 14.
The next digit of our result is 3. 
Result so far: 2177.83
The remainder is 14 after subtracting 126 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
The number 42 fits into 140 3 times, leaving a remainder of 14.
The next digit of our result is 3. 
Result so far: 2177.833
Deduct 126 from 140 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 2177.833 with a remaining 0.0014.
