Let's divide 470021 by 28
The aim is to understand the frequency of 28 in 470021.

Going ahead to step 1:
When dividing 4 by 28, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 28

Advancing to step 2:
If we divide 47 by 28, we get 1 and a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 28 from 47 and we're left with 19.
Append the next digit (0) from the dividend to 19 and continue with: 190 / 28

Moving on to step 3:
28 goes into 190 6 times with a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we subtract 168 from 190, we get 22.
Grab the next digit (0) from the dividend, add it to 22, then carry on: 220 / 28

Step 4:
When dividing 220 by 28, we get 7 with a remainder of 24.
Record the quotient 7 as the next digit in the result. 
Result so far: 167.0
Subtract 196 from 220 to get 24.
Bring next digit (2) of the dividend behind the 24 and repeat the process: 242 / 28

Moving on to step 5:
If we divide 242 by 28, we get 8 and a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 1678.0
Subtract 224 from 242 to get 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 28

Let's proceed to step 6:
The number 28 fits into 181 6 times, leaving a remainder of 13.
The number 6 becomes the next digit in our result. 
Result so far: 16786.0
Subtract 168 from 181 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
The number 28 fits into 130 4 times, leaving a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 16786.4
If we subtract 112 from 130, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
When dividing 180 by 28, we get 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 16786.46
Deduct 168 from 180 and we're left 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.

On to step 9:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 16786.464
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.

On to step 10:
28 goes into 80 2 times with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 16786.4642
If we take 56 away from 80, we end up 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 11:
28 goes into 240 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 16786.46428
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.

Step 12:
160 divided by 28 is 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 16786.464285
The remainder is 20 after subtracting 140 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
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: 16786.4642857
Subtracting 196 from 200 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 14:
40 divided by 28 is 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 16786.46428571
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.

In conclusion, the division gives 16786.46428571 with a balance of 1.2e-08.
