4815191 ÷ 233 
The aim is to understand the frequency of 233 in 4815191.

Advancing to step 1:
The number 233 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 233

Moving on to step 2:
233 goes into 48 0 times with a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 48 to get 48.
Include the next digit (1) from the dividend after 48, then repeat: 481 / 233

Let's proceed to step 3:
233 goes into 481 2 times with a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 466 from 481 to get 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 233

Step 4:
155 divided by 233 is 0 with a remainder of 155.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we subtract 0 from 155, we get 155.
Append the next digit (1) from the dividend to 155 and continue with: 1551 / 233

Going ahead to step 5:
The number 233 fits into 1551 6 times, leaving a remainder of 153.
Put 6 as the next digit of the answer. 
Result so far: 206.0
The remainder is 153 after subtracting 1398 from 1551.
Include the next digit (9) from the dividend after 153, then repeat: 1539 / 233

Let's proceed to step 6:
When dividing 1539 by 233, we get 6 with a remainder of 141.
Write down 6 as next digit of the result. 
Result so far: 2066.0
If we subtract 1398 from 1539, we get 141.
Fetch the next digit (1) from the dividend, attach it to 141 and continue: 1411 / 233

Let's proceed to step 7:
If we divide 1411 by 233, we get 6 and a remainder of 13.
Write down 6 as next digit of the result. 
Result so far: 20666.0
If we subtract 1398 from 1411, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 8:
If we divide 130 by 233, we get 0 and a remainder of 130.
The next digit of our result is 0. 
Result so far: 20666.0
The remainder is 130 after subtracting 0 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 9:
1300 divided by 233 is 5 with a remainder of 135.
Write down 5 as next digit of the result. 
Result so far: 20666.05
Subtract 1165 from 1300 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 10:
233 can be fit into 1350 5 times, resulting in a remainder of 185.
Write down 5 as next digit of the result. 
Result so far: 20666.055
If we subtract 1165 from 1350, we get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Our division results in 20666.055 with a remaining 0.0185.
