We look at the division of 243497 by 4 
The aim is to understand the frequency of 4 in 243497.

Moving on to step 1:
4 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 4

Going ahead to step 2:
The number 4 fits into 24 6 times, leaving a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 24 from 24 and we're left with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 4

Going ahead to step 3:
The number 4 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 60.0
Subtract 0 from 3 to get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 4

Moving on to step 4:
34 divided by 4 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 608.0
The remainder is 2 after subtracting 32 from 34.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 4

Let's proceed to step 5:
29 divided by 4 is 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 6087.0
Subtracting 28 from 29 leaves us with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 4

Step 6:
If we divide 17 by 4, we get 4 and a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 60874.0
Subtracting 16 from 17 leaves us 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.

Let's proceed to step 7:
The number 4 fits into 10 2 times, leaving a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 60874.2
Subtracting 8 from 10 leaves us 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.

Going ahead to step 8:
4 goes into 20 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 60874.25
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.

Going ahead to step 9:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 60874.25
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 10:
0 divided by 4 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 60874.25
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.

After the division, we end up with 60874.25 and a remainder of 0.0.
