We're dividing 924854 by 42 
The aim is to understand the frequency of 42 in 924854.

On to step 1:
If we divide 9 by 42, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 42

Let's proceed to step 2:
42 can be fit into 92 2 times, resulting in a remainder of 8.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 84 from 92 and we're left with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 42

Moving on to step 3:
When dividing 84 by 42, we get 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 22.0
If we take 84 away from 84, we end up with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 42

Advancing to step 4:
If we divide 8 by 42, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 220.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 42

Going ahead to step 5:
The number 42 fits into 85 2 times, leaving a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2202.0
Subtracting 84 from 85 leaves us with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 42

Let's proceed to step 6:
When dividing 14 by 42, we get 0 with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 22020.0
If we take 0 away from 14, we end up 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.

On to step 7:
The number 42 fits into 140 3 times, leaving a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 22020.3
Subtracting 126 from 140 leaves us 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.

On to step 8:
42 can be fit into 140 3 times, resulting in a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 22020.33
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 22020.33 with a remaining 0.014.
