Let's divide 593451 by 28
The aim is to understand the frequency of 28 in 593451.

Step 1:
28 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 28

Let's proceed to step 2:
When dividing 59 by 28, we get 2 with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 56 from 59 to get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 28

On to step 3:
If we divide 33 by 28, we get 1 and a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtracting 28 from 33 leaves us with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 28

On to step 4:
28 goes into 54 1 times with a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 211.0
Subtract 28 from 54 to get 26.
Fetch the next digit (5) from the dividend, attach it to 26 and continue: 265 / 28

Going ahead to step 5:
When dividing 265 by 28, we get 9 with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 2119.0
If we subtract 252 from 265, we get 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 28

Advancing to step 6:
28 can be fit into 131 4 times, resulting in a remainder of 19.
The number 4 becomes the next digit in our result. 
Result so far: 21194.0
Subtracting 112 from 131 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
The number 28 fits into 190 6 times, leaving a remainder of 22.
The next digit of our result is 6. 
Result so far: 21194.6
If we take 168 away from 190, we end up 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.

Going ahead to step 8:
The number 28 fits into 220 7 times, leaving a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 21194.67
If we subtract 196 from 220, 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.

Let's proceed to step 9:
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: 21194.678
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.

Advancing to step 10:
160 divided by 28 is 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 21194.6785
If we take 140 away from 160, we end up 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.

Let's proceed to step 11:
28 can be fit into 200 7 times, resulting in a remainder of 4.
The next digit of our result is 7. 
Result so far: 21194.67857
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.

Step 12:
If we divide 40 by 28, we get 1 and a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 21194.678571
Deduct 28 from 40 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.

Let's proceed to step 13:
28 goes into 120 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 21194.6785714
If we take 112 away from 120, we end up 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.

Let's proceed to step 14:
80 divided by 28 is 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 21194.67857142
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.

Our division results in 21194.67857142 with a remaining 2.4e-08.
