242394 ÷ 3 
The aim is to understand the frequency of 3 in 242394.

On to step 1:
When dividing 2 by 3, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 3

Step 2:
3 can be fit into 24 8 times, resulting in a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 24 away from 24, we end up with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 3

Going ahead to step 3:
When dividing 2 by 3, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 80.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 3

Going ahead to step 4:
If we divide 23 by 3, we get 7 and a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 807.0
If we take 21 away from 23, we end up with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 3

Step 5:
If we divide 29 by 3, we get 9 and a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 8079.0
Subtracting 27 from 29 leaves us with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 3

Advancing to step 6:
3 goes into 24 8 times with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 80798.0
If we take 24 away from 24, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
3 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 80798.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
3 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 80798.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 80798.0 with a remaining 0.0.
