Let's divide 23898243 by 224
The aim is to understand the frequency of 224 in 23898243.

On to step 1:
When dividing 2 by 224, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 224

On to step 2:
23 divided by 224 is 0 with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Bring next digit (8) of the dividend behind the 23 and repeat the process: 238 / 224

On to step 3:
224 can be fit into 238 1 times, resulting in a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 224 from 238 to get 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 224

Advancing to step 4:
When dividing 149 by 224, we get 0 with a remainder of 149.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 149, we get 149.
Bring next digit (8) of the dividend behind the 149 and repeat the process: 1498 / 224

Advancing to step 5:
224 goes into 1498 6 times with a remainder of 154.
Write down 6 as next digit of the result. 
Result so far: 106.0
Deduct 1344 from 1498 and we're left with 154.
Bring next digit (2) of the dividend behind the 154 and repeat the process: 1542 / 224

Moving on to step 6:
1542 divided by 224 is 6 with a remainder of 198.
Write down 6 as next digit of the result. 
Result so far: 1066.0
Subtract 1344 from 1542 to get 198.
Take the next digit (4) from the dividend and append it to 198, then repeat: 1984 / 224

On to step 7:
The number 224 fits into 1984 8 times, leaving a remainder of 192.
The next digit of our result is 8. 
Result so far: 10668.0
If we take 1792 away from 1984, we end up with 192.
Take the next digit (3) from the dividend and append it to 192, then repeat: 1923 / 224

Moving on to step 8:
224 goes into 1923 8 times with a remainder of 131.
The next digit of our result is 8. 
Result so far: 106688.0
Subtracting 1792 from 1923 leaves us with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Advancing to step 9:
When dividing 1310 by 224, we get 5 with a remainder of 190.
Write down 5 as next digit of the result. 
Result so far: 106688.5
If we take 1120 away from 1310, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 10:
224 can be fit into 1900 8 times, resulting in a remainder of 108.
Record the quotient 8 as the next digit in the result. 
Result so far: 106688.58
If we take 1792 away from 1900, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

On to step 11:
If we divide 1080 by 224, we get 4 and a remainder of 184.
Put 4 as the next digit of the answer. 
Result so far: 106688.584
If we take 896 away from 1080, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Let's proceed to step 12:
The number 224 fits into 1840 8 times, leaving a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 106688.5848
Subtract 1792 from 1840 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 13:
224 can be fit into 480 2 times, resulting in a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 106688.58482
Subtract 448 from 480 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 14:
320 divided by 224 is 1 with a remainder of 96.
Write down 1 as next digit of the result. 
Result so far: 106688.584821
If we subtract 224 from 320, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 15:
When dividing 960 by 224, we get 4 with a remainder of 64.
The next digit of our result is 4. 
Result so far: 106688.5848214
The remainder is 64 after subtracting 896 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 16:
When dividing 640 by 224, we get 2 with a remainder of 192.
Use 2 as the next digit of our solution. 
Result so far: 106688.58482142
The remainder is 192 after subtracting 448 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

After the division, we end up with 106688.58482142 and a remainder of 1.92e-07.
