We're dividing 711435 by 28 
The aim is to understand the frequency of 28 in 711435.

On to step 1:
7 divided by 28 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 28

Going ahead to step 2:
The number 28 fits into 71 2 times, leaving a remainder of 15.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 56 away from 71, we end up with 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 28

On to step 3:
When dividing 151 by 28, we get 5 with a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Subtract 140 from 151 to get 11.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 28

On to step 4:
28 goes into 114 4 times with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 254.0
If we take 112 away from 114, we end up with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 28

On to step 5:
23 divided by 28 is 0 with a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 2540.0
If we take 0 away from 23, we end up with 23.
Take the next digit (5) from the dividend and append it to 23, then repeat: 235 / 28

Going ahead to step 6:
28 can be fit into 235 8 times, resulting in a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 25408.0
Subtract 224 from 235 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
If we divide 110 by 28, we get 3 and a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 25408.3
If we subtract 84 from 110, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 8:
When dividing 260 by 28, we get 9 with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 25408.39
The remainder is 8 after subtracting 252 from 260.
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 9:
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: 25408.392
The remainder is 24 after subtracting 56 from 80.
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:
28 goes into 240 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 25408.3928
If we take 224 away from 240, we end up 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 11:
160 divided by 28 is 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 25408.39285
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 12:
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: 25408.392857
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.

On to step 13:
The number 28 fits into 40 1 times, leaving a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 25408.3928571
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.

On to step 14:
28 goes into 120 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 25408.39285714
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.

The quotient of the division is 25408.39285714, and the remainder is 8e-09.
