Let's divide 94215 by 3
The aim is to understand the frequency of 3 in 94215.

On to step 1:
9 divided by 3 is 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 9 away from 9, we end up with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 3

Going ahead to step 2:
The number 3 fits into 4 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 31.0
Deduct 3 from 4 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 3

Going ahead to step 3:
3 goes into 12 4 times with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 314.0
The remainder is 0 after subtracting 12 from 12.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 3

Going ahead to step 4:
3 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 3140.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 3

Step 5:
3 can be fit into 15 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 31405.0
If we subtract 15 from 15, 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.

Going ahead to step 6:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 31405.0
Subtract 0 from 0 to 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.

Let's proceed to step 7:
When dividing 0 by 3, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 31405.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 31405.0 and a remainder of 0.0.
