We look at the division of 97570115 by 224 
The aim is to understand the frequency of 224 in 97570115.

Step 1:
9 divided by 224 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 224

Moving on to step 2:
If we divide 97 by 224, we get 0 and a remainder of 97.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 97 after subtracting 0 from 97.
Include the next digit (5) from the dividend after 97, then repeat: 975 / 224

Advancing to step 3:
The number 224 fits into 975 4 times, leaving a remainder of 79.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 79 after subtracting 896 from 975.
Take the next digit (7) from the dividend and append it to 79, then repeat: 797 / 224

Going ahead to step 4:
When dividing 797 by 224, we get 3 with a remainder of 125.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Subtract 672 from 797 to get 125.
Grab the next digit (0) from the dividend, add it to 125, then carry on: 1250 / 224

Advancing to step 5:
If we divide 1250 by 224, we get 5 and a remainder of 130.
Use 5 as the next digit of our solution. 
Result so far: 435.0
The remainder is 130 after subtracting 1120 from 1250.
Take the next digit (1) from the dividend and append it to 130, then repeat: 1301 / 224

Going ahead to step 6:
If we divide 1301 by 224, we get 5 and a remainder of 181.
Record the quotient 5 as the next digit in the result. 
Result so far: 4355.0
Subtract 1120 from 1301 to get 181.
Take the next digit (1) from the dividend and append it to 181, then repeat: 1811 / 224

Advancing to step 7:
The number 224 fits into 1811 8 times, leaving a remainder of 19.
The next digit of our result is 8. 
Result so far: 43558.0
The remainder is 19 after subtracting 1792 from 1811.
Append the next digit (5) from the dividend to 19 and continue with: 195 / 224

Moving on to step 8:
If we divide 195 by 224, we get 0 and a remainder of 195.
Use 0 as the next digit of our solution. 
Result so far: 435580.0
Deduct 0 from 195 and we're left with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

On to step 9:
224 can be fit into 1950 8 times, resulting in a remainder of 158.
The next digit of our result is 8. 
Result so far: 435580.8
The remainder is 158 after subtracting 1792 from 1950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 10:
The number 224 fits into 1580 7 times, leaving a remainder of 12.
The next digit of our result is 7. 
Result so far: 435580.87
Deduct 1568 from 1580 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 11:
When dividing 120 by 224, we get 0 with a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 435580.87
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 12:
When dividing 1200 by 224, we get 5 with a remainder of 80.
The number 5 becomes the next digit in our result. 
Result so far: 435580.8705
The remainder is 80 after subtracting 1120 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 13:
If we divide 800 by 224, we get 3 and a remainder of 128.
Use 3 as the next digit of our solution. 
Result so far: 435580.87053
If we subtract 672 from 800, we 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.

Step 14:
224 can be fit into 1280 5 times, resulting in a remainder of 160.
Write down 5 as next digit of the result. 
Result so far: 435580.870535
The remainder is 160 after subtracting 1120 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 15:
1600 divided by 224 is 7 with a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 435580.8705357
Deduct 1568 from 1600 and we're left with 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 16:
If we divide 320 by 224, we get 1 and a remainder of 96.
The number 1 becomes the next digit in our result. 
Result so far: 435580.87053571
If we take 224 away from 320, we end up 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.

The final outcome is 435580.87053571, with a leftover of 9.6e-08.
