We divide 312375 by 28
The aim is to understand the frequency of 28 in 312375.

Let's proceed to step 1:
If we divide 3 by 28, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 28

Step 2:
The number 28 fits into 31 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 28 from 31 leaves us with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 28

Going ahead to step 3:
When dividing 32 by 28, we get 1 with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 28 from 32 to get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 28

Moving on to step 4:
28 can be fit into 43 1 times, resulting in a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 111.0
Deduct 28 from 43 and we're left with 15.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 28

Let's proceed to step 5:
If we divide 157 by 28, we get 5 and a remainder of 17.
The next digit of our result is 5. 
Result so far: 1115.0
Subtract 140 from 157 to get 17.
Grab the next digit (5) from the dividend, add it to 17, then carry on: 175 / 28

Advancing to step 6:
28 can be fit into 175 6 times, resulting in a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 11156.0
Deduct 168 from 175 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.

Let's proceed to step 7:
70 divided by 28 is 2 with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 11156.2
Subtract 56 from 70 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
When dividing 140 by 28, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 11156.25
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:
0 divided by 28 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 11156.25
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.

Going ahead to step 10:
The number 28 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 11156.25
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.

In conclusion, the division gives 11156.25 with a balance of 0.0.
