We're dividing 928379 by 3 
The aim is to understand the frequency of 3 in 928379.

Step 1:
When dividing 9 by 3, we get 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 0 after subtracting 9 from 9.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 3

Step 2:
If we divide 2 by 3, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 30.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 3

On to step 3:
3 can be fit into 28 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 309.0
If we take 27 away from 28, we end up with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 3

Moving on to step 4:
13 divided by 3 is 4 with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 3094.0
Subtract 12 from 13 to get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 3

Moving on to step 5:
3 goes into 17 5 times with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 30945.0
Subtracting 15 from 17 leaves us with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 3

Step 6:
3 goes into 29 9 times with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 309459.0
Deduct 27 from 29 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
If we divide 20 by 3, we get 6 and a remainder of 2.
The next digit of our result is 6. 
Result so far: 309459.6
If we take 18 away from 20, we end up with 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 8:
3 goes into 20 6 times with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 309459.66
Subtract 18 from 20 to 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.

The final outcome is 309459.66, with a leftover of 0.002.
