We're dividing 429764 by 28 
The aim is to understand the frequency of 28 in 429764.

Going ahead to step 1:
4 divided by 28 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 28

On to step 2:
42 divided by 28 is 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 28 from 42 and we're left with 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 28

Moving on to step 3:
149 divided by 28 is 5 with a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 140 from 149 leaves us with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 28

Moving on to step 4:
97 divided by 28 is 3 with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 153.0
Deduct 84 from 97 and we're left with 13.
Include the next digit (6) from the dividend after 13, then repeat: 136 / 28

On to step 5:
28 can be fit into 136 4 times, resulting in a remainder of 24.
The next digit of our result is 4. 
Result so far: 1534.0
The remainder is 24 after subtracting 112 from 136.
Grab the next digit (4) from the dividend, add it to 24, then carry on: 244 / 28

Step 6:
244 divided by 28 is 8 with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 15348.0
Subtract 224 from 244 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
28 goes into 200 7 times with a remainder of 4.
The next digit of our result is 7. 
Result so far: 15348.7
Subtract 196 from 200 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
28 goes into 40 1 times with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 15348.71
If we take 28 away from 40, we end up 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.

Advancing to step 9:
The number 28 fits into 120 4 times, leaving a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 15348.714
The remainder is 8 after subtracting 112 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
When dividing 80 by 28, we get 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 15348.7142
Subtracting 56 from 80 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.

Advancing to step 11:
28 goes into 240 8 times with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 15348.71428
The remainder is 16 after subtracting 224 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 12:
When dividing 160 by 28, we get 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 15348.714285
If we subtract 140 from 160, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 13:
28 can be fit into 200 7 times, resulting in a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 15348.7142857
Subtract 196 from 200 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 14:
When dividing 40 by 28, we get 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 15348.71428571
If we take 28 away from 40, we end up 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.

The final result is 15348.71428571 with a remainder of 1.2e-08.
