We divide 472373 by 28
The aim is to understand the frequency of 28 in 472373.

Going ahead 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
If we take 0 away from 4, we end up with 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 28

Moving on to step 2:
47 divided by 28 is 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 28 from 47 and we're left with 19.
Take the next digit (2) from the dividend and append it to 19, then repeat: 192 / 28

Moving on to step 3:
The number 28 fits into 192 6 times, leaving a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 16.0
The remainder is 24 after subtracting 168 from 192.
Append the next digit (3) from the dividend to 24 and continue with: 243 / 28

Let's proceed to step 4:
If we divide 243 by 28, we get 8 and a remainder of 19.
The number 8 becomes the next digit in our result. 
Result so far: 168.0
The remainder is 19 after subtracting 224 from 243.
Take the next digit (7) from the dividend and append it to 19, then repeat: 197 / 28

Step 5:
If we divide 197 by 28, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 1687.0
Subtract 196 from 197 to get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 28

Step 6:
13 divided by 28 is 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 16870.0
The remainder is 13 after subtracting 0 from 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:
28 goes into 130 4 times with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 16870.4
Deduct 112 from 130 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
28 goes into 180 6 times with a remainder of 12.
The next digit of our result is 6. 
Result so far: 16870.46
If we subtract 168 from 180, we 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.

Going ahead to step 9:
28 goes into 120 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 16870.464
Deduct 112 from 120 and we're left with 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 10:
If we divide 80 by 28, we get 2 and a remainder of 24.
The next digit of our result is 2. 
Result so far: 16870.4642
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.

On to step 11:
When dividing 240 by 28, we get 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 16870.46428
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.

Let's proceed to step 12:
If we divide 160 by 28, we get 5 and a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 16870.464285
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.

Going ahead to step 13:
28 goes into 200 7 times with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 16870.4642857
If we take 196 away from 200, we end up 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.

Advancing to step 14:
28 can be fit into 40 1 times, resulting in a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 16870.46428571
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.

The final outcome is 16870.46428571, with a leftover of 1.2e-08.
