We look at the division of 993128 by 4 
The aim is to understand the frequency of 4 in 993128.

Let's proceed to 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.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 4

Step 2:
4 goes into 19 4 times with a remainder of 3.
The next digit of our result is 4. 
Result so far: 24.0
Subtracting 16 from 19 leaves us with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 4

Going ahead to step 3:
4 goes into 33 8 times with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 248.0
If we take 32 away from 33, we end up with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 4

Step 4:
When dividing 11 by 4, we get 2 with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 2482.0
Subtracting 8 from 11 leaves us with 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 4

Step 5:
4 goes into 32 8 times with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 24828.0
If we subtract 32 from 32, we get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 4

Let's proceed to step 6:
When dividing 8 by 4, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 248282.0
The remainder is 0 after subtracting 8 from 8.
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 7:
0 divided by 4 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 248282.0
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.

On to step 8:
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: 248282.0
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.

Our division results in 248282.0 with a remaining 0.0.
