Let's divide 547331 by 28
The aim is to understand the frequency of 28 in 547331.

Step 1:
If we divide 5 by 28, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 28

Let's proceed to step 2:
If we divide 54 by 28, we get 1 and a remainder of 26.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 28 from 54 leaves us with 26.
Grab the next digit (7) from the dividend, add it to 26, then carry on: 267 / 28

Advancing to step 3:
28 can be fit into 267 9 times, resulting in a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtract 252 from 267 to get 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 28

Going ahead to step 4:
28 goes into 153 5 times with a remainder of 13.
Write down 5 as next digit of the result. 
Result so far: 195.0
If we take 140 away from 153, we end up with 13.
Take the next digit (3) from the dividend and append it to 13, then repeat: 133 / 28

Advancing to step 5:
28 can be fit into 133 4 times, resulting in a remainder of 21.
Put 4 as the next digit of the answer. 
Result so far: 1954.0
If we take 112 away from 133, we end up with 21.
Fetch the next digit (1) from the dividend, attach it to 21 and continue: 211 / 28

Going ahead to step 6:
28 can be fit into 211 7 times, resulting in a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 19547.0
The remainder is 15 after subtracting 196 from 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
When dividing 150 by 28, we get 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 19547.5
If we take 140 away from 150, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
100 divided by 28 is 3 with a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 19547.53
If we take 84 away from 100, 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 9:
If we divide 160 by 28, we get 5 and a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 19547.535
Deduct 140 from 160 and we're left 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.

Advancing to step 10:
When dividing 200 by 28, we get 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 19547.5357
Deduct 196 from 200 and we're left 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.

On to step 11:
The number 28 fits into 40 1 times, leaving a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 19547.53571
The remainder is 12 after subtracting 28 from 40.
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 12:
28 goes into 120 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 19547.535714
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.

Going ahead to step 13:
28 goes into 80 2 times with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 19547.5357142
If we subtract 56 from 80, we 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.

Moving on to step 14:
If we divide 240 by 28, we get 8 and a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 19547.53571428
Subtract 224 from 240 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 19547.53571428, with a leftover of 1.6e-08.
