We look at the division of 72240654 by 224 
The aim is to understand the frequency of 224 in 72240654.

Moving on to step 1:
The number 224 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 224

On to step 2:
If we divide 72 by 224, we get 0 and a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Include the next digit (2) from the dividend after 72, then repeat: 722 / 224

Let's proceed to step 3:
When dividing 722 by 224, we get 3 with a remainder of 50.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 672 from 722, we get 50.
Include the next digit (4) from the dividend after 50, then repeat: 504 / 224

On to step 4:
224 can be fit into 504 2 times, resulting in a remainder of 56.
The next digit of our result is 2. 
Result so far: 32.0
If we take 448 away from 504, we end up with 56.
Include the next digit (0) from the dividend after 56, then repeat: 560 / 224

On to step 5:
If we divide 560 by 224, we get 2 and a remainder of 112.
The next digit of our result is 2. 
Result so far: 322.0
Subtract 448 from 560 to get 112.
Fetch the next digit (6) from the dividend, attach it to 112 and continue: 1126 / 224

Step 6:
The number 224 fits into 1126 5 times, leaving a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 3225.0
Deduct 1120 from 1126 and we're left with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 224

Moving on to step 7:
224 goes into 65 0 times with a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 32250.0
Subtracting 0 from 65 leaves us with 65.
Include the next digit (4) from the dividend after 65, then repeat: 654 / 224

Advancing to step 8:
224 goes into 654 2 times with a remainder of 206.
The next digit of our result is 2. 
Result so far: 322502.0
Subtracting 448 from 654 leaves us with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Moving on to step 9:
If we divide 2060 by 224, we get 9 and a remainder of 44.
Write down 9 as next digit of the result. 
Result so far: 322502.9
The remainder is 44 after subtracting 2016 from 2060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 10:
The number 224 fits into 440 1 times, leaving a remainder of 216.
The next digit of our result is 1. 
Result so far: 322502.91
Deduct 224 from 440 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Moving on to step 11:
If we divide 2160 by 224, we get 9 and a remainder of 144.
The next digit of our result is 9. 
Result so far: 322502.919
If we take 2016 away from 2160, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 12:
224 can be fit into 1440 6 times, resulting in a remainder of 96.
Record the quotient 6 as the next digit in the result. 
Result so far: 322502.9196
Subtracting 1344 from 1440 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 13:
960 divided by 224 is 4 with a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 322502.91964
If we subtract 896 from 960, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 14:
If we divide 640 by 224, we get 2 and a remainder of 192.
Write down 2 as next digit of the result. 
Result so far: 322502.919642
If we subtract 448 from 640, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 15:
224 goes into 1920 8 times with a remainder of 128.
The number 8 becomes the next digit in our result. 
Result so far: 322502.9196428
Subtract 1792 from 1920 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 16:
The number 224 fits into 1280 5 times, leaving a remainder of 160.
Put 5 as the next digit of the answer. 
Result so far: 322502.91964285
If we take 1120 away from 1280, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Our division results in 322502.91964285 with a remaining 1.6e-07.
