817001 divided by 28 
The aim is to understand the frequency of 28 in 817001.

Moving on to step 1:
8 divided by 28 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 28

Moving on to step 2:
If we divide 81 by 28, we get 2 and a remainder of 25.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 56 from 81 to get 25.
Append the next digit (7) from the dividend to 25 and continue with: 257 / 28

Moving on to step 3:
257 divided by 28 is 9 with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
If we take 252 away from 257, we end up with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 28

Advancing to step 4:
The number 28 fits into 50 1 times, leaving a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 291.0
Deduct 28 from 50 and we're left with 22.
Fetch the next digit (0) from the dividend, attach it to 22 and continue: 220 / 28

Going ahead to step 5:
28 goes into 220 7 times with a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 2917.0
Subtract 196 from 220 to get 24.
Grab the next digit (1) from the dividend, add it to 24, then carry on: 241 / 28

On to step 6:
When dividing 241 by 28, we get 8 with a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 29178.0
The remainder is 17 after subtracting 224 from 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
170 divided by 28 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 29178.6
Deduct 168 from 170 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
28 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 29178.6
Subtracting 0 from 20 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.

Step 9:
28 goes into 200 7 times with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 29178.607
The remainder is 4 after subtracting 196 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
When dividing 40 by 28, we get 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 29178.6071
Deduct 28 from 40 and we're left 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.

Moving on to step 11:
28 can be fit into 120 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 29178.60714
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 12:
When dividing 80 by 28, we get 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 29178.607142
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.

Going ahead to step 13:
28 goes into 240 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 29178.6071428
Subtract 224 from 240 to 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.

Going ahead to step 14:
If we divide 160 by 28, we get 5 and a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 29178.60714285
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.

The quotient of the division is 29178.60714285, and the remainder is 2e-08.
