We look at the division of 63936275 by 224 
The aim is to understand the frequency of 224 in 63936275.

Going ahead to step 1:
224 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 224

On to step 2:
If we divide 63 by 224, we get 0 and a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Take the next digit (9) from the dividend and append it to 63, then repeat: 639 / 224

Let's proceed to step 3:
When dividing 639 by 224, we get 2 with a remainder of 191.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 448 away from 639, we end up with 191.
Append the next digit (3) from the dividend to 191 and continue with: 1913 / 224

Advancing to step 4:
When dividing 1913 by 224, we get 8 with a remainder of 121.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Subtracting 1792 from 1913 leaves us with 121.
Take the next digit (6) from the dividend and append it to 121, then repeat: 1216 / 224

On to step 5:
224 goes into 1216 5 times with a remainder of 96.
Record the quotient 5 as the next digit in the result. 
Result so far: 285.0
Subtract 1120 from 1216 to get 96.
Take the next digit (2) from the dividend and append it to 96, then repeat: 962 / 224

Advancing to step 6:
The number 224 fits into 962 4 times, leaving a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 2854.0
Subtracting 896 from 962 leaves us with 66.
Fetch the next digit (7) from the dividend, attach it to 66 and continue: 667 / 224

On to step 7:
224 goes into 667 2 times with a remainder of 219.
The number 2 becomes the next digit in our result. 
Result so far: 28542.0
Deduct 448 from 667 and we're left with 219.
Bring next digit (5) of the dividend behind the 219 and repeat the process: 2195 / 224

Going ahead to step 8:
When dividing 2195 by 224, we get 9 with a remainder of 179.
The next digit of our result is 9. 
Result so far: 285429.0
If we subtract 2016 from 2195, we get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Going ahead to step 9:
1790 divided by 224 is 7 with a remainder of 222.
Put 7 as the next digit of the answer. 
Result so far: 285429.7
If we subtract 1568 from 1790, we get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

On to step 10:
The number 224 fits into 2220 9 times, leaving a remainder of 204.
The number 9 becomes the next digit in our result. 
Result so far: 285429.79
If we take 2016 away from 2220, we end up with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Going ahead to step 11:
224 goes into 2040 9 times with a remainder of 24.
The next digit of our result is 9. 
Result so far: 285429.799
Subtracting 2016 from 2040 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 285429.799 and a remainder of 0.0024.
