We're dividing 910936 by 28 
The aim is to understand the frequency of 28 in 910936.

On to step 1:
When dividing 9 by 28, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 28

Step 2:
91 divided by 28 is 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 84 from 91 to get 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 28

Let's proceed to step 3:
28 goes into 70 2 times with a remainder of 14.
The next digit of our result is 2. 
Result so far: 32.0
If we subtract 56 from 70, we get 14.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 28

Advancing to step 4:
When dividing 149 by 28, we get 5 with a remainder of 9.
The next digit of our result is 5. 
Result so far: 325.0
The remainder is 9 after subtracting 140 from 149.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 28

Moving on to step 5:
The number 28 fits into 93 3 times, leaving a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 3253.0
If we take 84 away from 93, we end up with 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 28

Advancing to step 6:
28 can be fit into 96 3 times, resulting in a remainder of 12.
The next digit of our result is 3. 
Result so far: 32533.0
If we take 84 away from 96, 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 7:
The number 28 fits into 120 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 32533.4
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.

Going ahead to step 8:
The number 28 fits into 80 2 times, leaving a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 32533.42
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.

Going ahead to step 9:
When dividing 240 by 28, we get 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 32533.428
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 can be fit into 160 5 times, resulting in a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 32533.4285
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.

Advancing to step 11:
When dividing 200 by 28, we get 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 32533.42857
If we subtract 196 from 200, we get 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:
28 can be fit into 40 1 times, resulting in a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 32533.428571
Subtract 28 from 40 to 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.
Use 4 as the next digit of our solution. 
Result so far: 32533.4285714
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.

Going ahead to step 14:
The number 28 fits into 80 2 times, leaving a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 32533.42857142
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.

Our division results in 32533.42857142 with a remaining 2.4e-08.
