5576 divided by 18 
The aim is to understand the frequency of 18 in 5576.

Let's proceed to step 1:
5 divided by 18 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 18

Let's proceed to step 2:
If we divide 55 by 18, we get 3 and a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 54 from 55 leaves us with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 18

Let's proceed to step 3:
If we divide 17 by 18, we get 0 and a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Subtracting 0 from 17 leaves us with 17.
Bring next digit (6) of the dividend behind the 17 and repeat the process: 176 / 18

Advancing to step 4:
18 goes into 176 9 times with a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 309.0
Subtracting 162 from 176 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 5:
18 goes into 140 7 times with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 309.7
Deduct 126 from 140 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 6:
140 divided by 18 is 7 with a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 309.77
Subtracting 126 from 140 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 309.77, with a leftover of 0.014.
