We divide 364217 by 3
The aim is to understand the frequency of 3 in 364217.

Moving on to step 1:
3 can be fit into 3 1 times, resulting in a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 3 from 3 leaves us with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 3

Advancing to step 2:
3 goes into 6 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 6 from 6, we get 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 3

Step 3:
4 divided by 3 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 121.0
The remainder is 1 after subtracting 3 from 4.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 3

Advancing to step 4:
12 divided by 3 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 1214.0
The remainder is 0 after subtracting 12 from 12.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 3

Let's proceed to step 5:
3 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 12140.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 3

Let's proceed to step 6:
3 can be fit into 17 5 times, resulting in a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 121405.0
Subtract 15 from 17 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.

Going ahead to step 7:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 121405.6
Deduct 18 from 20 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.

Let's proceed to step 8:
3 can be fit into 20 6 times, resulting in a remainder of 2.
The next digit of our result is 6. 
Result so far: 121405.66
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.

After the division, we end up with 121405.66 and a remainder of 0.002.
