We divide 673565 by 28
The aim is to understand the frequency of 28 in 673565.

Going ahead to step 1:
6 divided by 28 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 28

On to step 2:
28 can be fit into 67 2 times, resulting in a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 56 from 67, we get 11.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 28

Moving on to step 3:
The number 28 fits into 113 4 times, leaving a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 24.0
The remainder is 1 after subtracting 112 from 113.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 28

Let's proceed to step 4:
28 goes into 15 0 times with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 240.0
Subtract 0 from 15 to get 15.
Bring next digit (6) of the dividend behind the 15 and repeat the process: 156 / 28

Moving on to step 5:
28 goes into 156 5 times with a remainder of 16.
Use 5 as the next digit of our solution. 
Result so far: 2405.0
Deduct 140 from 156 and we're left with 16.
Grab the next digit (5) from the dividend, add it to 16, then carry on: 165 / 28

Moving on to step 6:
28 goes into 165 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 24055.0
Deduct 140 from 165 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 7:
If we divide 250 by 28, we get 8 and a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 24055.8
If we take 224 away from 250, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 8:
The number 28 fits into 260 9 times, leaving a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 24055.89
Subtracting 252 from 260 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.

On to step 9:
80 divided by 28 is 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 24055.892
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.

Step 10:
The number 28 fits into 240 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 24055.8928
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.

Going ahead to step 11:
The number 28 fits into 160 5 times, leaving a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 24055.89285
The remainder is 20 after subtracting 140 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
28 goes into 200 7 times with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 24055.892857
Subtracting 196 from 200 leaves us 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.

Advancing to step 13:
When dividing 40 by 28, we get 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 24055.8928571
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 14:
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: 24055.89285714
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 final outcome is 24055.89285714, with a leftover of 8e-09.
