148488 ÷ 28 
The aim is to understand the frequency of 28 in 148488.

Going ahead to step 1:
When dividing 1 by 28, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 28

Advancing to step 2:
28 goes into 14 0 times with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Include the next digit (8) from the dividend after 14, then repeat: 148 / 28

Step 3:
28 can be fit into 148 5 times, resulting in a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 140 from 148 and we're left with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 28

Advancing to step 4:
If we divide 84 by 28, we get 3 and a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
If we subtract 84 from 84, we get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 28

Moving on to step 5:
If we divide 8 by 28, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 530.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 28

Step 6:
The number 28 fits into 88 3 times, leaving a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 5303.0
If we take 84 away from 88, we end up 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.

Moving on to step 7:
When dividing 40 by 28, we get 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 5303.1
The remainder is 12 after subtracting 28 from 40.
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 8:
120 divided by 28 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 5303.14
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.

Moving on to step 9:
80 divided by 28 is 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 5303.142
Subtracting 56 from 80 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
28 goes into 240 8 times with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 5303.1428
Subtract 224 from 240 to 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 11:
When dividing 160 by 28, we get 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 5303.14285
If we take 140 away from 160, we end up 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.

Moving on to step 12:
200 divided by 28 is 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 5303.142857
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:
28 can be fit into 40 1 times, resulting in a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 5303.1428571
Subtract 28 from 40 to 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.
Put 4 as the next digit of the answer. 
Result so far: 5303.14285714
If we take 112 away from 120, we end up 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.

After the division, we end up with 5303.14285714 and a remainder of 8e-09.
