We divide 553574 by 4
The aim is to understand the frequency of 4 in 553574.

Going ahead to step 1:
5 divided by 4 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 4 from 5 and we're left with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 4

Step 2:
4 goes into 15 3 times with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 12 from 15 leaves us with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 4

Let's proceed to step 3:
4 goes into 33 8 times with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 138.0
Deduct 32 from 33 and we're left with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 4

Step 4:
4 can be fit into 15 3 times, resulting in a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 1383.0
Subtracting 12 from 15 leaves us with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 4

Advancing to step 5:
37 divided by 4 is 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 13839.0
If we subtract 36 from 37, we get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 4

Step 6:
14 divided by 4 is 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 138393.0
If we subtract 12 from 14, we get 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 7:
20 divided by 4 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 138393.5
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.

Moving on to step 8:
When dividing 0 by 4, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 138393.5
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.

On to step 9:
4 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 138393.5
Deduct 0 from 0 and we're left 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.

The quotient of the division is 138393.5, and the remainder is 0.0.
