805400 divided by 28 
The aim is to understand the frequency of 28 in 805400.

On to step 1:
8 divided by 28 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 28

Advancing to step 2:
When dividing 80 by 28, we get 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 56 from 80 to get 24.
Grab the next digit (5) from the dividend, add it to 24, then carry on: 245 / 28

Moving on to step 3:
245 divided by 28 is 8 with a remainder of 21.
Use 8 as the next digit of our solution. 
Result so far: 28.0
The remainder is 21 after subtracting 224 from 245.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 28

On to step 4:
28 goes into 214 7 times with a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 287.0
The remainder is 18 after subtracting 196 from 214.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 28

On to step 5:
28 can be fit into 180 6 times, resulting in a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 2876.0
If we subtract 168 from 180, we get 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 28

Step 6:
If we divide 120 by 28, we get 4 and a remainder of 8.
The next digit of our result is 4. 
Result so far: 28764.0
If we take 112 away from 120, we end up 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.

Moving on to step 7:
28 can be fit into 80 2 times, resulting in a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 28764.2
Deduct 56 from 80 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.

Step 8:
240 divided by 28 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 28764.28
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.

On to step 9:
The number 28 fits into 160 5 times, leaving a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 28764.285
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.

Moving on to step 10:
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: 28764.2857
Subtract 196 from 200 to 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.

Moving on to step 11:
28 goes into 40 1 times with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 28764.28571
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 12:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 28764.285714
Subtracting 112 from 120 leaves us 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.

Advancing to step 13:
28 can be fit into 80 2 times, resulting in a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 28764.2857142
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.

Advancing to step 14:
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: 28764.28571428
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.

Our division results in 28764.28571428 with a remaining 1.6e-08.
