We're dividing 4035840 by 224 
The aim is to understand the frequency of 224 in 4035840.

Moving on to step 1:
If we divide 4 by 224, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 224

Going ahead to step 2:
40 divided by 224 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Include the next digit (3) from the dividend after 40, then repeat: 403 / 224

Step 3:
If we divide 403 by 224, we get 1 and a remainder of 179.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 224 from 403 leaves us with 179.
Take the next digit (5) from the dividend and append it to 179, then repeat: 1795 / 224

Step 4:
224 goes into 1795 8 times with a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we subtract 1792 from 1795, we get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 224

Moving on to step 5:
If we divide 38 by 224, we get 0 and a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 180.0
If we take 0 away from 38, we end up with 38.
Grab the next digit (4) from the dividend, add it to 38, then carry on: 384 / 224

Going ahead to step 6:
When dividing 384 by 224, we get 1 with a remainder of 160.
Put 1 as the next digit of the answer. 
Result so far: 1801.0
Subtracting 224 from 384 leaves us with 160.
Bring next digit (0) of the dividend behind the 160 and repeat the process: 1600 / 224

Advancing to step 7:
1600 divided by 224 is 7 with a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 18017.0
If we take 1568 away from 1600, we end up 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 8:
224 goes into 320 1 times with a remainder of 96.
Record the quotient 1 as the next digit in the result. 
Result so far: 18017.1
Subtracting 224 from 320 leaves us 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.

Going ahead to step 9:
The number 224 fits into 960 4 times, leaving a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 18017.14
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.

On to step 10:
224 goes into 640 2 times with a remainder of 192.
The next digit of our result is 2. 
Result so far: 18017.142
Deduct 448 from 640 and we're left 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.

Step 11:
224 can be fit into 1920 8 times, resulting in a remainder of 128.
The next digit of our result is 8. 
Result so far: 18017.1428
The remainder is 128 after subtracting 1792 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 12:
The number 224 fits into 1280 5 times, leaving a remainder of 160.
Record the quotient 5 as the next digit in the result. 
Result so far: 18017.14285
Subtract 1120 from 1280 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 13:
The number 224 fits into 1600 7 times, leaving a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 18017.142857
Subtract 1568 from 1600 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.
The next digit of our result is 1. 
Result so far: 18017.1428571
The remainder is 96 after subtracting 224 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 15:
The number 224 fits into 960 4 times, leaving a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 18017.14285714
Subtract 896 from 960 to 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.

The final outcome is 18017.14285714, with a leftover of 6.4e-08.
