We're dividing 846942 by 3 
The aim is to understand the frequency of 3 in 846942.

On to step 1:
The number 3 fits into 8 2 times, leaving a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 6 from 8, we get 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 3

Advancing to step 2:
3 can be fit into 24 8 times, resulting in a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
If we subtract 24 from 24, we get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 3

Moving on to step 3:
3 can be fit into 6 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 282.0
If we take 6 away from 6, we end up with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 3

Step 4:
3 can be fit into 9 3 times, resulting in a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 2823.0
If we subtract 9 from 9, we get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 3

Let's proceed to step 5:
4 divided by 3 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 28231.0
Subtract 3 from 4 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 3

Advancing to step 6:
If we divide 12 by 3, we get 4 and a remainder of 0.
The next digit of our result is 4. 
Result so far: 282314.0
Deduct 12 from 12 and we're left 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 7:
3 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 282314.0
If we subtract 0 from 0, we get 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 8:
0 divided by 3 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 282314.0
Deduct 0 from 0 and we're left 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.

The quotient of the division is 282314.0, and the remainder is 0.0.
