Let's divide 71223808 by 223
The aim is to understand the frequency of 223 in 71223808.

Step 1:
The number 223 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 223

Moving on to step 2:
223 goes into 71 0 times with a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Take the next digit (2) from the dividend and append it to 71, then repeat: 712 / 223

On to step 3:
223 can be fit into 712 3 times, resulting in a remainder of 43.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 669 from 712 leaves us with 43.
Fetch the next digit (2) from the dividend, attach it to 43 and continue: 432 / 223

Advancing to step 4:
223 goes into 432 1 times with a remainder of 209.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Subtracting 223 from 432 leaves us with 209.
Fetch the next digit (3) from the dividend, attach it to 209 and continue: 2093 / 223

Moving on to step 5:
2093 divided by 223 is 9 with a remainder of 86.
The number 9 becomes the next digit in our result. 
Result so far: 319.0
If we take 2007 away from 2093, we end up with 86.
Include the next digit (8) from the dividend after 86, then repeat: 868 / 223

Moving on to step 6:
When dividing 868 by 223, we get 3 with a remainder of 199.
The next digit of our result is 3. 
Result so far: 3193.0
If we take 669 away from 868, we end up with 199.
Grab the next digit (0) from the dividend, add it to 199, then carry on: 1990 / 223

Let's proceed to step 7:
1990 divided by 223 is 8 with a remainder of 206.
Record the quotient 8 as the next digit in the result. 
Result so far: 31938.0
Subtracting 1784 from 1990 leaves us with 206.
Include the next digit (8) from the dividend after 206, then repeat: 2068 / 223

Advancing to step 8:
2068 divided by 223 is 9 with a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 319389.0
Subtract 2007 from 2068 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 9:
The number 223 fits into 610 2 times, leaving a remainder of 164.
Record the quotient 2 as the next digit in the result. 
Result so far: 319389.2
Deduct 446 from 610 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

On to step 10:
When dividing 1640 by 223, we get 7 with a remainder of 79.
Use 7 as the next digit of our solution. 
Result so far: 319389.27
Subtract 1561 from 1640 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 11:
790 divided by 223 is 3 with a remainder of 121.
Use 3 as the next digit of our solution. 
Result so far: 319389.273
Subtract 669 from 790 to get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Moving on to step 12:
When dividing 1210 by 223, we get 5 with a remainder of 95.
The next digit of our result is 5. 
Result so far: 319389.2735
The remainder is 95 after subtracting 1115 from 1210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 13:
223 goes into 950 4 times with a remainder of 58.
Put 4 as the next digit of the answer. 
Result so far: 319389.27354
If we take 892 away from 950, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 14:
580 divided by 223 is 2 with a remainder of 134.
The next digit of our result is 2. 
Result so far: 319389.273542
Subtract 446 from 580 to get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

On to step 15:
The number 223 fits into 1340 6 times, leaving a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 319389.2735426
Subtract 1338 from 1340 to 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.

On to step 16:
When dividing 20 by 223, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 319389.2735426
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 319389.2735426 and a remainder of 2e-08.
