We look at the division of 28976 by 775 
The aim is to understand the frequency of 775 in 28976.

Moving on to step 1:
If we divide 2 by 775, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 775

Advancing to step 2:
775 goes into 28 0 times with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Fetch the next digit (9) from the dividend, attach it to 28 and continue: 289 / 775

Step 3:
The number 775 fits into 289 0 times, leaving a remainder of 289.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 289, we get 289.
Grab the next digit (7) from the dividend, add it to 289, then carry on: 2897 / 775

On to step 4:
The number 775 fits into 2897 3 times, leaving a remainder of 572.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 2325 from 2897 leaves us with 572.
Take the next digit (6) from the dividend and append it to 572, then repeat: 5726 / 775

Going ahead to step 5:
5726 divided by 775 is 7 with a remainder of 301.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
Deduct 5425 from 5726 and we're left with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Going ahead to step 6:
The number 775 fits into 3010 3 times, leaving a remainder of 685.
Put 3 as the next digit of the answer. 
Result so far: 37.3
Deduct 2325 from 3010 and we're left with 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

Going ahead to step 7:
The number 775 fits into 6850 8 times, leaving a remainder of 650.
Use 8 as the next digit of our solution. 
Result so far: 37.38
Subtract 6200 from 6850 to get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Let's proceed to step 8:
The number 775 fits into 6500 8 times, leaving a remainder of 300.
Use 8 as the next digit of our solution. 
Result so far: 37.388
If we take 6200 away from 6500, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final result is 37.388 with a remainder of 0.03.
