29538641 divided by 224 
The aim is to understand the frequency of 224 in 29538641.

Moving on to step 1:
If we divide 2 by 224, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 224

On to step 2:
When dividing 29 by 224, we get 0 with a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 29, we get 29.
Take the next digit (5) from the dividend and append it to 29, then repeat: 295 / 224

Let's proceed to step 3:
224 goes into 295 1 times with a remainder of 71.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 224 from 295 and we're left with 71.
Include the next digit (3) from the dividend after 71, then repeat: 713 / 224

Moving on to step 4:
If we divide 713 by 224, we get 3 and a remainder of 41.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 672 from 713 and we're left with 41.
Grab the next digit (8) from the dividend, add it to 41, then carry on: 418 / 224

Going ahead to step 5:
224 goes into 418 1 times with a remainder of 194.
The next digit of our result is 1. 
Result so far: 131.0
If we subtract 224 from 418, we get 194.
Bring next digit (6) of the dividend behind the 194 and repeat the process: 1946 / 224

On to step 6:
224 goes into 1946 8 times with a remainder of 154.
Put 8 as the next digit of the answer. 
Result so far: 1318.0
If we subtract 1792 from 1946, we get 154.
Include the next digit (4) from the dividend after 154, then repeat: 1544 / 224

Moving on to step 7:
The number 224 fits into 1544 6 times, leaving a remainder of 200.
Write down 6 as next digit of the result. 
Result so far: 13186.0
Subtract 1344 from 1544 to get 200.
Take the next digit (1) from the dividend and append it to 200, then repeat: 2001 / 224

Step 8:
224 goes into 2001 8 times with a remainder of 209.
The next digit of our result is 8. 
Result so far: 131868.0
If we take 1792 away from 2001, we end up with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Going ahead to step 9:
224 goes into 2090 9 times with a remainder of 74.
Use 9 as the next digit of our solution. 
Result so far: 131868.9
Deduct 2016 from 2090 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 10:
The number 224 fits into 740 3 times, leaving a remainder of 68.
The next digit of our result is 3. 
Result so far: 131868.93
If we take 672 away from 740, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 11:
224 goes into 680 3 times with a remainder of 8.
The next digit of our result is 3. 
Result so far: 131868.933
Deduct 672 from 680 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 131868.933 with a remaining 0.0008.
