430384 divided by 28 
The aim is to understand the frequency of 28 in 430384.

On to step 1:
If we divide 4 by 28, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 28

Let's proceed to step 2:
43 divided by 28 is 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 28 from 43 and we're left with 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 28

Moving on to step 3:
150 divided by 28 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 140 from 150 and we're left with 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 28

Going ahead to step 4:
The number 28 fits into 103 3 times, leaving a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 153.0
Subtract 84 from 103 to get 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 28

Let's proceed to step 5:
28 can be fit into 198 7 times, resulting in a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 1537.0
Subtracting 196 from 198 leaves us with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 28

Advancing to step 6:
When dividing 24 by 28, we get 0 with a remainder of 24.
The next digit of our result is 0. 
Result so far: 15370.0
Subtracting 0 from 24 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.

Moving on to step 7:
28 goes into 240 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 15370.8
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.

On to step 8:
28 can be fit into 160 5 times, resulting in a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 15370.85
Subtracting 140 from 160 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
When dividing 200 by 28, we get 7 with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 15370.857
The remainder is 4 after subtracting 196 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
40 divided by 28 is 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 15370.8571
Subtract 28 from 40 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
28 goes into 120 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 15370.85714
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.

Moving on to step 12:
The number 28 fits into 80 2 times, leaving a remainder of 24.
The next digit of our result is 2. 
Result so far: 15370.857142
Subtract 56 from 80 to get 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 13:
28 goes into 240 8 times with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 15370.8571428
Subtracting 224 from 240 leaves us 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.

Going ahead to step 14:
28 can be fit into 160 5 times, resulting in a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 15370.85714285
Subtracting 140 from 160 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 15370.85714285 with a remaining 2e-08.
