We look at the division of 70157085 by 224 
The aim is to understand the frequency of 224 in 70157085.

Step 1:
If we divide 7 by 224, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 224

Step 2:
If we divide 70 by 224, we get 0 and a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Take the next digit (1) from the dividend and append it to 70, then repeat: 701 / 224

Step 3:
The number 224 fits into 701 3 times, leaving a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 672 away from 701, we end up with 29.
Grab the next digit (5) from the dividend, add it to 29, then carry on: 295 / 224

Advancing to step 4:
If we divide 295 by 224, we get 1 and a remainder of 71.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Subtract 224 from 295 to get 71.
Grab the next digit (7) from the dividend, add it to 71, then carry on: 717 / 224

Step 5:
When dividing 717 by 224, we get 3 with a remainder of 45.
Record the quotient 3 as the next digit in the result. 
Result so far: 313.0
The remainder is 45 after subtracting 672 from 717.
Take the next digit (0) from the dividend and append it to 45, then repeat: 450 / 224

On to step 6:
450 divided by 224 is 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 3132.0
The remainder is 2 after subtracting 448 from 450.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 224

Let's proceed to step 7:
The number 224 fits into 28 0 times, leaving a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 31320.0
Subtracting 0 from 28 leaves us with 28.
Append the next digit (5) from the dividend to 28 and continue with: 285 / 224

Step 8:
When dividing 285 by 224, we get 1 with a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 313201.0
Subtract 224 from 285 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 9:
610 divided by 224 is 2 with a remainder of 162.
Use 2 as the next digit of our solution. 
Result so far: 313201.2
If we subtract 448 from 610, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Step 10:
1620 divided by 224 is 7 with a remainder of 52.
Record the quotient 7 as the next digit in the result. 
Result so far: 313201.27
Subtracting 1568 from 1620 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 11:
If we divide 520 by 224, we get 2 and a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 313201.272
Subtracting 448 from 520 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 12:
When dividing 720 by 224, we get 3 with a remainder of 48.
The next digit of our result is 3. 
Result so far: 313201.2723
Subtracting 672 from 720 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 13:
224 goes into 480 2 times with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 313201.27232
Deduct 448 from 480 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.

Advancing to step 14:
320 divided by 224 is 1 with a remainder of 96.
Put 1 as the next digit of the answer. 
Result so far: 313201.272321
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.

Let's proceed to step 15:
224 can be fit into 960 4 times, resulting in a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 313201.2723214
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.

Advancing to step 16:
640 divided by 224 is 2 with a remainder of 192.
Write down 2 as next digit of the result. 
Result so far: 313201.27232142
Subtracting 448 from 640 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

The final result is 313201.27232142 with a remainder of 1.92e-07.
