Let's divide 447285 by 4
The aim is to understand the frequency of 4 in 447285.

Advancing to step 1:
4 goes into 4 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
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

Advancing to step 2:
4 goes into 4 1 times with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 4 from 4, we get 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 4

On to step 3:
If we divide 7 by 4, we get 1 and a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 111.0
Deduct 4 from 7 and we're left with 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 4

Advancing to step 4:
The number 4 fits into 32 8 times, leaving a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 1118.0
Subtract 32 from 32 to get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 4

Let's proceed to step 5:
8 divided by 4 is 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 11182.0
Subtracting 8 from 8 leaves us with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 4

Going ahead to step 6:
If we divide 5 by 4, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 111821.0
Deduct 4 from 5 and we're left 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.

On to step 7:
If we divide 10 by 4, we get 2 and a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 111821.2
Subtract 8 from 10 to 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 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: 111821.25
If we subtract 20 from 20, 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 9:
When dividing 0 by 4, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 111821.25
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.

On to step 10:
4 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 111821.25
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.

After the division, we end up with 111821.25 and a remainder of 0.0.
