We look at the division of 414750 by 3 
The aim is to understand the frequency of 3 in 414750.

On to step 1:
3 can be fit into 4 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
If we take 3 away from 4, we end up with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 3

Going ahead to step 2:
If we divide 11 by 3, we get 3 and a remainder of 2.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 9 from 11 leaves us with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 3

On to step 3:
24 divided by 3 is 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 138.0
If we take 24 away from 24, we end up with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 3

Let's proceed to step 4:
The number 3 fits into 7 2 times, leaving a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 1382.0
If we take 6 away from 7, we end up with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 3

Step 5:
When dividing 15 by 3, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 13825.0
If we subtract 15 from 15, we get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 3

Step 6:
The number 3 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 138250.0
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.

On to step 7:
When dividing 0 by 3, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 138250.0
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.

On to step 8:
3 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 138250.0
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.

Our division results in 138250.0 with a remaining 0.0.
