We're dividing 452485 by 4 
The aim is to understand the frequency of 4 in 452485.

Advancing to step 1:
The number 4 fits into 4 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 4 from 4 leaves us with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 4

Let's proceed to step 2:
4 goes into 5 1 times with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 4 from 5 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 4

Moving on to step 3:
4 can be fit into 12 3 times, resulting in a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 113.0
If we subtract 12 from 12, we get 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 4

Going ahead to step 4:
4 divided by 4 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1131.0
Subtracting 4 from 4 leaves us with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 4

Going ahead to step 5:
8 divided by 4 is 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 11312.0
If we take 8 away from 8, we end up with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 4

Let's proceed to step 6:
The number 4 fits into 5 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 113121.0
Subtracting 4 from 5 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
The number 4 fits into 10 2 times, leaving a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 113121.2
If we subtract 8 from 10, 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.

Advancing to step 8:
4 can be fit into 20 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 113121.25
Subtracting 20 from 20 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.

Going ahead to step 9:
4 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 113121.25
If we take 0 away from 0, we end up 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.

Let's proceed to step 10:
0 divided by 4 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 113121.25
If we take 0 away from 0, we end up 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.

The final outcome is 113121.25, with a leftover of 0.0.
