We're dividing 123782 by 28 
The aim is to understand the frequency of 28 in 123782.

Moving on to step 1:
The number 28 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 28

On to step 2:
If we divide 12 by 28, we get 0 and a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 28

Let's proceed to step 3:
28 can be fit into 123 4 times, resulting in a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 112 from 123 and we're left with 11.
Bring next digit (7) of the dividend behind the 11 and repeat the process: 117 / 28

On to step 4:
28 can be fit into 117 4 times, resulting in a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 44.0
Subtracting 112 from 117 leaves us with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 28

Step 5:
58 divided by 28 is 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 442.0
Subtracting 56 from 58 leaves us with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 28

On to step 6:
When dividing 22 by 28, we get 0 with a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 4420.0
Subtract 0 from 22 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
28 can be fit into 220 7 times, resulting in a remainder of 24.
The number 7 becomes the next digit in our result. 
Result so far: 4420.7
The remainder is 24 after subtracting 196 from 220.
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 8:
When dividing 240 by 28, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 4420.78
Subtracting 224 from 240 leaves us 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.

Step 9:
160 divided by 28 is 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 4420.785
Subtracting 140 from 160 leaves us 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.

On to step 10:
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: 4420.7857
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.

Moving on to step 11:
40 divided by 28 is 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 4420.78571
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.

Advancing to step 12:
120 divided by 28 is 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 4420.785714
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 13:
If we divide 80 by 28, we get 2 and a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 4420.7857142
The remainder is 24 after subtracting 56 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 14:
28 can be fit into 240 8 times, resulting in a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 4420.78571428
Deduct 224 from 240 and we're left 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.

The quotient of the division is 4420.78571428, and the remainder is 1.6e-08.
