We look at the division of 40810858 by 223 
The aim is to understand the frequency of 223 in 40810858.

Step 1:
223 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 223

Step 2:
The number 223 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Take the next digit (8) from the dividend and append it to 40, then repeat: 408 / 223

On to step 3:
223 goes into 408 1 times with a remainder of 185.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 223 from 408 leaves us with 185.
Fetch the next digit (1) from the dividend, attach it to 185 and continue: 1851 / 223

Advancing to step 4:
223 goes into 1851 8 times with a remainder of 67.
The next digit of our result is 8. 
Result so far: 18.0
Subtracting 1784 from 1851 leaves us with 67.
Fetch the next digit (0) from the dividend, attach it to 67 and continue: 670 / 223

Advancing to step 5:
223 goes into 670 3 times with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 183.0
If we subtract 669 from 670, we get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 223

On to step 6:
The number 223 fits into 18 0 times, leaving a remainder of 18.
The next digit of our result is 0. 
Result so far: 1830.0
The remainder is 18 after subtracting 0 from 18.
Bring next digit (5) of the dividend behind the 18 and repeat the process: 185 / 223

Moving on to step 7:
223 goes into 185 0 times with a remainder of 185.
Record the quotient 0 as the next digit in the result. 
Result so far: 18300.0
Subtracting 0 from 185 leaves us with 185.
Append the next digit (8) from the dividend to 185 and continue with: 1858 / 223

Advancing to step 8:
223 can be fit into 1858 8 times, resulting in a remainder of 74.
Put 8 as the next digit of the answer. 
Result so far: 183008.0
The remainder is 74 after subtracting 1784 from 1858.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 9:
If we divide 740 by 223, we get 3 and a remainder of 71.
The next digit of our result is 3. 
Result so far: 183008.3
If we take 669 away from 740, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 10:
710 divided by 223 is 3 with a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 183008.33
If we take 669 away from 710, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

The final result is 183008.33 with a remainder of 0.041.
