996443 ÷ 4 
The aim is to understand the frequency of 4 in 996443.

Step 1:
4 can be fit into 9 2 times, resulting in a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 1 after subtracting 8 from 9.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 4

Moving on to step 2:
4 can be fit into 19 4 times, resulting in a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
Subtracting 16 from 19 leaves us with 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 4

On to step 3:
The number 4 fits into 36 9 times, leaving a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 249.0
The remainder is 0 after subtracting 36 from 36.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 4

Going ahead to step 4:
If we divide 4 by 4, we get 1 and a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 2491.0
Subtracting 4 from 4 leaves us with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 4

Step 5:
When dividing 4 by 4, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 24911.0
If we subtract 4 from 4, we get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 4

On to step 6:
4 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 249110.0
Subtracting 0 from 3 leaves us 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:
If we divide 30 by 4, we get 7 and a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 249110.7
The remainder is 2 after subtracting 28 from 30.
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.
Record the quotient 5 as the next digit in the result. 
Result so far: 249110.75
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.

Step 9:
4 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 249110.75
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.

Moving 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: 249110.75
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 249110.75 and a remainder of 0.0.
