Let's divide 361250 by 3
The aim is to understand the frequency of 3 in 361250.

On to step 1:
3 goes into 3 1 times with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
If we take 3 away from 3, we end up with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 3

Let's proceed to step 2:
6 divided by 3 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 0 after subtracting 6 from 6.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 3

Step 3:
1 divided by 3 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 120.0
If we subtract 0 from 1, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 3

Let's proceed to step 4:
12 divided by 3 is 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 1204.0
The remainder is 0 after subtracting 12 from 12.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 3

Going ahead to step 5:
When dividing 5 by 3, we get 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 12041.0
The remainder is 2 after subtracting 3 from 5.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 3

Step 6:
3 goes into 20 6 times with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 120416.0
If we subtract 18 from 20, we 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.

Let's proceed to step 7:
The number 3 fits into 20 6 times, leaving a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 120416.6
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.

Going ahead to step 8:
The number 3 fits into 20 6 times, leaving a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 120416.66
Subtracting 18 from 20 leaves us 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.

In conclusion, the division gives 120416.66 with a balance of 0.002.
