We're dividing 209353 by 28 
The aim is to understand the frequency of 28 in 209353.

On to step 1:
2 divided by 28 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 28

On to step 2:
28 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 28

Moving on to step 3:
209 divided by 28 is 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 196 from 209 leaves us with 13.
Bring next digit (3) of the dividend behind the 13 and repeat the process: 133 / 28

Moving on to step 4:
The number 28 fits into 133 4 times, leaving a remainder of 21.
Use 4 as the next digit of our solution. 
Result so far: 74.0
The remainder is 21 after subtracting 112 from 133.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 28

Moving on to step 5:
28 can be fit into 215 7 times, resulting in a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 747.0
Subtracting 196 from 215 leaves us with 19.
Fetch the next digit (3) from the dividend, attach it to 19 and continue: 193 / 28

Step 6:
28 can be fit into 193 6 times, resulting in a remainder of 25.
Put 6 as the next digit of the answer. 
Result so far: 7476.0
Subtract 168 from 193 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 7:
If we divide 250 by 28, we get 8 and a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 7476.8
Deduct 224 from 250 and we're left 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.

Step 8:
28 goes into 260 9 times with a remainder of 8.
The next digit of our result is 9. 
Result so far: 7476.89
Deduct 252 from 260 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.

Step 9:
The number 28 fits into 80 2 times, leaving a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 7476.892
If we take 56 away from 80, we end up 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.

Step 10:
240 divided by 28 is 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 7476.8928
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.

Moving on to step 11:
28 can be fit into 160 5 times, resulting in a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 7476.89285
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.

Let's proceed to step 12:
28 goes into 200 7 times with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 7476.892857
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.

Going ahead to step 13:
28 goes into 40 1 times with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 7476.8928571
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.

Moving on to step 14:
When dividing 120 by 28, we get 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 7476.89285714
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.

The final outcome is 7476.89285714, with a leftover of 8e-09.
