Let's divide 909432 by 28
The aim is to understand the frequency of 28 in 909432.

Moving on to step 1:
28 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 28

On to step 2:
28 can be fit into 90 3 times, resulting in a remainder of 6.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 6 after subtracting 84 from 90.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 28

Going ahead to step 3:
The number 28 fits into 69 2 times, leaving a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
Deduct 56 from 69 and we're left with 13.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 28

Moving on to step 4:
When dividing 134 by 28, we get 4 with a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 324.0
Deduct 112 from 134 and we're left with 22.
Include the next digit (3) from the dividend after 22, then repeat: 223 / 28

Advancing to step 5:
When dividing 223 by 28, we get 7 with a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 3247.0
The remainder is 27 after subtracting 196 from 223.
Fetch the next digit (2) from the dividend, attach it to 27 and continue: 272 / 28

On to step 6:
272 divided by 28 is 9 with a remainder of 20.
The next digit of our result is 9. 
Result so far: 32479.0
Deduct 252 from 272 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.

Moving on to step 7:
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: 32479.7
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.

On to step 8:
If we divide 40 by 28, we get 1 and a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 32479.71
If we take 28 away from 40, we end up 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.

Going ahead to step 9:
The number 28 fits into 120 4 times, leaving a remainder of 8.
The next digit of our result is 4. 
Result so far: 32479.714
If we subtract 112 from 120, we 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.

Going ahead to step 10:
28 goes into 80 2 times with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 32479.7142
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.

Advancing to step 11:
28 can be fit into 240 8 times, resulting in a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 32479.71428
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.

Advancing to step 12:
160 divided by 28 is 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 32479.714285
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.

Going ahead to step 13:
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: 32479.7142857
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.

Step 14:
28 goes into 40 1 times with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 32479.71428571
If we take 28 away from 40, we end up 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.

The final outcome is 32479.71428571, with a leftover of 1.2e-08.
