Let's divide 449012 by 4
The aim is to understand the frequency of 4 in 449012.

Advancing to step 1:
The number 4 fits into 4 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 4 from 4 and we're left with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 4

Let's proceed to step 2:
4 goes into 4 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 4 away from 4, we end up with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 4

On to step 3:
9 divided by 4 is 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 112.0
If we take 8 away from 9, we end up with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 4

On to step 4:
4 can be fit into 10 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 1122.0
If we subtract 8 from 10, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 4

Going ahead to step 5:
If we divide 21 by 4, we get 5 and a remainder of 1.
The next digit of our result is 5. 
Result so far: 11225.0
The remainder is 1 after subtracting 20 from 21.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 4

Moving on to step 6:
12 divided by 4 is 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 112253.0
Subtract 12 from 12 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.

Going ahead to step 7:
If we divide 0 by 4, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 112253.0
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.

Let's proceed to step 8:
If we divide 0 by 4, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 112253.0
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.

The quotient of the division is 112253.0, and the remainder is 0.0.
