We're dividing 394049 by 28 
The aim is to understand the frequency of 28 in 394049.

Step 1:
3 divided by 28 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 28

On to step 2:
If we divide 39 by 28, we get 1 and a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 11 after subtracting 28 from 39.
Fetch the next digit (4) from the dividend, attach it to 11 and continue: 114 / 28

Moving on to step 3:
The number 28 fits into 114 4 times, leaving a remainder of 2.
The next digit of our result is 4. 
Result so far: 14.0
Subtracting 112 from 114 leaves us with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 28

Advancing to step 4:
The number 28 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 140.0
If we subtract 0 from 20, we get 20.
Grab the next digit (4) from the dividend, add it to 20, then carry on: 204 / 28

Let's proceed to step 5:
The number 28 fits into 204 7 times, leaving a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 1407.0
Deduct 196 from 204 and we're left with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 28

Going ahead to step 6:
When dividing 89 by 28, we get 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 14073.0
Subtract 84 from 89 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
50 divided by 28 is 1 with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 14073.1
The remainder is 22 after subtracting 28 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 8:
If we divide 220 by 28, we get 7 and a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 14073.17
Deduct 196 from 220 and we're left 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 9:
240 divided by 28 is 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 14073.178
If we subtract 224 from 240, we 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.

Advancing to step 10:
28 goes into 160 5 times with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 14073.1785
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:
When dividing 200 by 28, we get 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 14073.17857
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 12:
28 can be fit into 40 1 times, resulting in a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 14073.178571
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.

Let's proceed to step 13:
When dividing 120 by 28, we get 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 14073.1785714
Subtract 112 from 120 to get 8.
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 14:
When dividing 80 by 28, we get 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 14073.17857142
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.

The final outcome is 14073.17857142, with a leftover of 2.4e-08.
