We're dividing 148925 by 28 
The aim is to understand the frequency of 28 in 148925.

Moving on to step 1:
When dividing 1 by 28, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 28

Advancing to step 2:
When dividing 14 by 28, we get 0 with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 28

Step 3:
The number 28 fits into 148 5 times, leaving a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 140 from 148, we get 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 28

Let's proceed to step 4:
The number 28 fits into 89 3 times, leaving a remainder of 5.
The next digit of our result is 3. 
Result so far: 53.0
Subtracting 84 from 89 leaves us with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 28

Going ahead to step 5:
If we divide 52 by 28, we get 1 and a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 531.0
Subtracting 28 from 52 leaves us with 24.
Fetch the next digit (5) from the dividend, attach it to 24 and continue: 245 / 28

Going ahead to step 6:
28 can be fit into 245 8 times, resulting in a remainder of 21.
Record the quotient 8 as the next digit in the result. 
Result so far: 5318.0
Subtracting 224 from 245 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
The number 28 fits into 210 7 times, leaving a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 5318.7
The remainder is 14 after subtracting 196 from 210.
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.
Use 5 as the next digit of our solution. 
Result so far: 5318.75
Deduct 140 from 140 and we're left 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.

Step 9:
28 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5318.75
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.

On to step 10:
The number 28 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5318.75
If we subtract 0 from 0, 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.

The final outcome is 5318.75, with a leftover of 0.0.
