We're dividing 243607 by 28 
The aim is to understand the frequency of 28 in 243607.

On to step 1:
2 divided by 28 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 28

Step 2:
28 can be fit into 24 0 times, resulting in a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 24 leaves us with 24.
Fetch the next digit (3) from the dividend, attach it to 24 and continue: 243 / 28

Going ahead to step 3:
When dividing 243 by 28, we get 8 with a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 224 from 243 leaves us with 19.
Append the next digit (6) from the dividend to 19 and continue with: 196 / 28

Advancing to step 4:
If we divide 196 by 28, we get 7 and a remainder of 0.
The next digit of our result is 7. 
Result so far: 87.0
Subtract 196 from 196 to get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 28

On to step 5:
The number 28 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 870.0
If we subtract 0 from 0, we get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 28

Advancing to step 6:
If we divide 7 by 28, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 8700.0
Deduct 0 from 7 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
When dividing 70 by 28, we get 2 with a remainder of 14.
The next digit of our result is 2. 
Result so far: 8700.2
The remainder is 14 after subtracting 56 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
When dividing 140 by 28, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 8700.25
If we subtract 140 from 140, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
0 divided by 28 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 8700.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
0 divided by 28 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8700.25
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 8700.25, with a leftover of 0.0.
