We look at the division of 999447 by 4 
The aim is to understand the frequency of 4 in 999447.

On to step 1:
The number 4 fits into 9 2 times, leaving a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 8 from 9 leaves us with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 4

Step 2:
4 can be fit into 19 4 times, resulting in a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 24.0
The remainder is 3 after subtracting 16 from 19.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 4

Let's proceed to step 3:
When dividing 39 by 4, we get 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 249.0
Subtracting 36 from 39 leaves us with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 4

Moving on to step 4:
If we divide 34 by 4, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 2498.0
Subtract 32 from 34 to get 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 4

Let's proceed to step 5:
When dividing 24 by 4, we get 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 24986.0
The remainder is 0 after subtracting 24 from 24.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 4

Advancing to step 6:
7 divided by 4 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 249861.0
If we take 4 away from 7, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
4 goes into 30 7 times with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 249861.7
Deduct 28 from 30 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.

Advancing to step 8:
The number 4 fits into 20 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 249861.75
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.

Going ahead to step 9:
4 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 249861.75
Subtracting 0 from 0 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.

Let's proceed to step 10:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 249861.75
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.

After the division, we end up with 249861.75 and a remainder of 0.0.
