675344 divided by 28 
The aim is to understand the frequency of 28 in 675344.

Moving on to step 1:
When dividing 6 by 28, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 28

Advancing to step 2:
The number 28 fits into 67 2 times, leaving a remainder of 11.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 56 from 67 to get 11.
Bring next digit (5) of the dividend behind the 11 and repeat the process: 115 / 28

Advancing to step 3:
If we divide 115 by 28, we get 4 and a remainder of 3.
The next digit of our result is 4. 
Result so far: 24.0
Deduct 112 from 115 and we're left with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 28

Step 4:
The number 28 fits into 33 1 times, leaving a remainder of 5.
The next digit of our result is 1. 
Result so far: 241.0
Subtracting 28 from 33 leaves us with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 28

Moving on to step 5:
The number 28 fits into 54 1 times, leaving a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 2411.0
Deduct 28 from 54 and we're left with 26.
Bring next digit (4) of the dividend behind the 26 and repeat the process: 264 / 28

On to step 6:
If we divide 264 by 28, we get 9 and a remainder of 12.
The next digit of our result is 9. 
Result so far: 24119.0
If we take 252 away from 264, 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.

On to step 7:
120 divided by 28 is 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 24119.4
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.

Advancing to step 8:
The number 28 fits into 80 2 times, leaving a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 24119.42
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.

On to step 9:
240 divided by 28 is 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 24119.428
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.

Step 10:
If we divide 160 by 28, we get 5 and a remainder of 20.
The next digit of our result is 5. 
Result so far: 24119.4285
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.

Step 11:
The number 28 fits into 200 7 times, leaving a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 24119.42857
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.

Step 12:
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: 24119.428571
Subtracting 28 from 40 leaves us 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.

Advancing to step 13:
28 goes into 120 4 times with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 24119.4285714
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.

On to step 14:
80 divided by 28 is 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 24119.42857142
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.

After the division, we end up with 24119.42857142 and a remainder of 2.4e-08.
