We're dividing 51956304 by 223 
The aim is to understand the frequency of 223 in 51956304.

Moving on to step 1:
If we divide 5 by 223, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 223

Let's proceed to step 2:
223 can be fit into 51 0 times, resulting in a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Take the next digit (9) from the dividend and append it to 51, then repeat: 519 / 223

Going ahead to step 3:
The number 223 fits into 519 2 times, leaving a remainder of 73.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 446 from 519 to get 73.
Bring next digit (5) of the dividend behind the 73 and repeat the process: 735 / 223

Let's proceed to step 4:
735 divided by 223 is 3 with a remainder of 66.
The next digit of our result is 3. 
Result so far: 23.0
If we take 669 away from 735, we end up with 66.
Append the next digit (6) from the dividend to 66 and continue with: 666 / 223

Step 5:
666 divided by 223 is 2 with a remainder of 220.
Write down 2 as next digit of the result. 
Result so far: 232.0
The remainder is 220 after subtracting 446 from 666.
Take the next digit (3) from the dividend and append it to 220, then repeat: 2203 / 223

Advancing to step 6:
When dividing 2203 by 223, we get 9 with a remainder of 196.
The next digit of our result is 9. 
Result so far: 2329.0
If we subtract 2007 from 2203, we get 196.
Fetch the next digit (0) from the dividend, attach it to 196 and continue: 1960 / 223

Moving on to step 7:
1960 divided by 223 is 8 with a remainder of 176.
Record the quotient 8 as the next digit in the result. 
Result so far: 23298.0
The remainder is 176 after subtracting 1784 from 1960.
Fetch the next digit (4) from the dividend, attach it to 176 and continue: 1764 / 223

Moving on to step 8:
When dividing 1764 by 223, we get 7 with a remainder of 203.
Write down 7 as next digit of the result. 
Result so far: 232987.0
If we take 1561 away from 1764, we end up with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Step 9:
223 can be fit into 2030 9 times, resulting in a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 232987.9
If we subtract 2007 from 2030, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 10:
230 divided by 223 is 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 232987.91
Subtract 223 from 230 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 11:
223 can be fit into 70 0 times, resulting in a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 232987.91
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 12:
223 goes into 700 3 times with a remainder of 31.
Use 3 as the next digit of our solution. 
Result so far: 232987.9103
If we subtract 669 from 700, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 13:
If we divide 310 by 223, we get 1 and a remainder of 87.
Write down 1 as next digit of the result. 
Result so far: 232987.91031
If we subtract 223 from 310, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Moving on to step 14:
870 divided by 223 is 3 with a remainder of 201.
The number 3 becomes the next digit in our result. 
Result so far: 232987.910313
If we take 669 away from 870, we end up with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Let's proceed to step 15:
2010 divided by 223 is 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 232987.9103139
Subtracting 2007 from 2010 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 16:
If we divide 30 by 223, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 232987.9103139
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Our division results in 232987.9103139 with a remaining 3e-08.
