445849 ÷ 4 
The aim is to understand the frequency of 4 in 445849.

Step 1:
4 can be fit into 4 1 times, resulting in a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 4 away from 4, we end up with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 4

Moving on to step 2:
4 divided by 4 is 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 4 from 4 to get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 4

Moving on to step 3:
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: 111.0
Subtracting 4 from 5 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 4

Moving on to step 4:
When dividing 18 by 4, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 1114.0
Subtract 16 from 18 to get 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 4

Advancing to step 5:
4 goes into 24 6 times with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 11146.0
If we take 24 away from 24, we end up with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 4

On to step 6:
4 goes into 9 2 times with a remainder of 1.
The next digit of our result is 2. 
Result so far: 111462.0
The remainder is 1 after subtracting 8 from 9.
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:
4 goes into 10 2 times with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 111462.2
Deduct 8 from 10 and we're left 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.

Let's proceed to step 8:
20 divided by 4 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 111462.25
Subtract 20 from 20 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.

Let's proceed to step 9:
0 divided by 4 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 111462.25
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.

On to step 10:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 111462.25
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.

The quotient of the division is 111462.25, and the remainder is 0.0.
