144394 ÷ 28 
The aim is to understand the frequency of 28 in 144394.

On to step 1:
28 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 28

Let's proceed to step 2:
28 can be fit into 14 0 times, resulting in a remainder of 14.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Grab the next digit (4) from the dividend, add it to 14, then carry on: 144 / 28

Step 3:
The number 28 fits into 144 5 times, leaving a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 140 from 144 and we're left with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 28

Advancing to step 4:
If we divide 43 by 28, we get 1 and a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 51.0
Subtracting 28 from 43 leaves us with 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 28

On to step 5:
When dividing 159 by 28, we get 5 with a remainder of 19.
Use 5 as the next digit of our solution. 
Result so far: 515.0
The remainder is 19 after subtracting 140 from 159.
Fetch the next digit (4) from the dividend, attach it to 19 and continue: 194 / 28

Moving on to step 6:
If we divide 194 by 28, we get 6 and a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 5156.0
If we take 168 away from 194, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 7:
28 goes into 260 9 times with a remainder of 8.
The next digit of our result is 9. 
Result so far: 5156.9
The remainder is 8 after subtracting 252 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
28 goes into 80 2 times with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 5156.92
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.

On to step 9:
When dividing 240 by 28, we get 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 5156.928
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.

Let's proceed to step 10:
160 divided by 28 is 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 5156.9285
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.

Advancing to step 11:
The number 28 fits into 200 7 times, leaving a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 5156.92857
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.

Moving on to step 12:
When dividing 40 by 28, we get 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 5156.928571
If we subtract 28 from 40, 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.

On to step 13:
When dividing 120 by 28, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 5156.9285714
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.

Let's proceed to step 14:
When dividing 80 by 28, we get 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 5156.92857142
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.

The final result is 5156.92857142 with a remainder of 2.4e-08.
