430634 ÷ 28 
The aim is to understand the frequency of 28 in 430634.

Advancing to step 1:
If we divide 4 by 28, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 28

On to step 2:
43 divided by 28 is 1 with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 28 from 43, we get 15.
Fetch the next digit (0) from the dividend, attach it to 15 and continue: 150 / 28

Moving on to step 3:
28 can be fit into 150 5 times, resulting in a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 140 from 150 to get 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 28

Advancing to step 4:
The number 28 fits into 106 3 times, leaving a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 153.0
If we take 84 away from 106, we end up with 22.
Include the next digit (3) from the dividend after 22, then repeat: 223 / 28

Advancing to step 5:
28 goes into 223 7 times with a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 1537.0
Deduct 196 from 223 and we're left with 27.
Fetch the next digit (4) from the dividend, attach it to 27 and continue: 274 / 28

Moving on to step 6:
The number 28 fits into 274 9 times, leaving a remainder of 22.
The next digit of our result is 9. 
Result so far: 15379.0
Subtracting 252 from 274 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
28 can be fit into 220 7 times, resulting in a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 15379.7
The remainder is 24 after subtracting 196 from 220.
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 8:
The number 28 fits into 240 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 15379.78
Deduct 224 from 240 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
When dividing 160 by 28, we get 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 15379.785
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.

Let's proceed to step 10:
28 goes into 200 7 times with a remainder of 4.
The next digit of our result is 7. 
Result so far: 15379.7857
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.

Step 11:
28 goes into 40 1 times with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 15379.78571
Subtracting 28 from 40 leaves us 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 12:
28 goes into 120 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 15379.785714
Subtract 112 from 120 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 13:
The number 28 fits into 80 2 times, leaving a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 15379.7857142
The remainder is 24 after subtracting 56 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 14:
The number 28 fits into 240 8 times, leaving a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 15379.78571428
If we take 224 away from 240, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 15379.78571428 with a balance of 1.6e-08.
