544990 ÷ 4 
The aim is to understand the frequency of 4 in 544990.

Moving on to step 1:
When dividing 5 by 4, we get 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 1 after subtracting 4 from 5.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 4

Advancing to step 2:
If we divide 14 by 4, we get 3 and a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 13.0
The remainder is 2 after subtracting 12 from 14.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 4

Going ahead to step 3:
The number 4 fits into 24 6 times, leaving a remainder of 0.
The next digit of our result is 6. 
Result so far: 136.0
Deduct 24 from 24 and we're left with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 4

Going ahead to step 4:
4 can be fit into 9 2 times, resulting in a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 1362.0
The remainder is 1 after subtracting 8 from 9.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 4

Advancing to step 5:
The number 4 fits into 19 4 times, leaving a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 13624.0
If we subtract 16 from 19, we get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 4

Moving on to step 6:
30 divided by 4 is 7 with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 136247.0
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.

Step 7:
4 goes into 20 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 136247.5
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.

Moving on to step 8:
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: 136247.5
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.

Let's proceed to step 9:
If we divide 0 by 4, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 136247.5
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.

The final result is 136247.5 with a remainder of 0.0.
