124231 divided by 28 
The aim is to understand the frequency of 28 in 124231.

On to step 1:
28 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 28

Step 2:
The number 28 fits into 12 0 times, leaving a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 28

Going ahead to step 3:
When dividing 124 by 28, we get 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 112 from 124 leaves us with 12.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 28

Step 4:
The number 28 fits into 122 4 times, leaving a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
The remainder is 10 after subtracting 112 from 122.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 28

Let's proceed to step 5:
28 can be fit into 103 3 times, resulting in a remainder of 19.
The next digit of our result is 3. 
Result so far: 443.0
If we subtract 84 from 103, we get 19.
Bring next digit (1) of the dividend behind the 19 and repeat the process: 191 / 28

Step 6:
191 divided by 28 is 6 with a remainder of 23.
Write down 6 as next digit of the result. 
Result so far: 4436.0
The remainder is 23 after subtracting 168 from 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
The number 28 fits into 230 8 times, leaving a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 4436.8
If we subtract 224 from 230, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
28 goes into 60 2 times with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 4436.82
The remainder is 4 after subtracting 56 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
The number 28 fits into 40 1 times, leaving a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 4436.821
Deduct 28 from 40 and we're left with 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 10:
The number 28 fits into 120 4 times, leaving a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 4436.8214
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.

On to step 11:
If we divide 80 by 28, we get 2 and a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 4436.82142
Deduct 56 from 80 and we're left 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.

Let's proceed to step 12:
28 can be fit into 240 8 times, resulting in a remainder of 16.
The next digit of our result is 8. 
Result so far: 4436.821428
The remainder is 16 after subtracting 224 from 240.
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 13:
If we divide 160 by 28, we get 5 and a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 4436.8214285
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.

Moving on to step 14:
200 divided by 28 is 7 with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 4436.82142857
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.

After the division, we end up with 4436.82142857 and a remainder of 4e-09.
