We're dividing 441363 by 3 
The aim is to understand the frequency of 3 in 441363.

Going ahead to step 1:
4 divided by 3 is 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 3 from 4, we get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 3

Let's proceed to step 2:
3 can be fit into 14 4 times, resulting in a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 2 after subtracting 12 from 14.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 3

Advancing to step 3:
21 divided by 3 is 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 147.0
The remainder is 0 after subtracting 21 from 21.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 3

Moving on to step 4:
3 goes into 3 1 times with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1471.0
Deduct 3 from 3 and we're left with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 3

Advancing to step 5:
The number 3 fits into 6 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 14712.0
The remainder is 0 after subtracting 6 from 6.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 3

On to step 6:
3 goes into 3 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 147121.0
The remainder is 0 after subtracting 3 from 3.
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:
3 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 147121.0
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.

Step 8:
0 divided by 3 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 147121.0
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.

Our division results in 147121.0 with a remaining 0.0.
