We're dividing 28075409 by 960 
The aim is to understand the frequency of 960 in 28075409.

Going ahead to step 1:
960 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 960

Moving on to step 2:
If we divide 28 by 960, we get 0 and a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Fetch the next digit (0) from the dividend, attach it to 28 and continue: 280 / 960

Let's proceed to step 3:
If we divide 280 by 960, we get 0 and a remainder of 280.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 280 to get 280.
Fetch the next digit (7) from the dividend, attach it to 280 and continue: 2807 / 960

Advancing to step 4:
960 goes into 2807 2 times with a remainder of 887.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1920 from 2807 to get 887.
Grab the next digit (5) from the dividend, add it to 887, then carry on: 8875 / 960

Advancing to step 5:
When dividing 8875 by 960, we get 9 with a remainder of 235.
Use 9 as the next digit of our solution. 
Result so far: 29.0
If we subtract 8640 from 8875, we get 235.
Grab the next digit (4) from the dividend, add it to 235, then carry on: 2354 / 960

Step 6:
When dividing 2354 by 960, we get 2 with a remainder of 434.
Put 2 as the next digit of the answer. 
Result so far: 292.0
Subtracting 1920 from 2354 leaves us with 434.
Take the next digit (0) from the dividend and append it to 434, then repeat: 4340 / 960

On to step 7:
When dividing 4340 by 960, we get 4 with a remainder of 500.
Write down 4 as next digit of the result. 
Result so far: 2924.0
Deduct 3840 from 4340 and we're left with 500.
Fetch the next digit (9) from the dividend, attach it to 500 and continue: 5009 / 960

Moving on to step 8:
960 can be fit into 5009 5 times, resulting in a remainder of 209.
Record the quotient 5 as the next digit in the result. 
Result so far: 29245.0
If we take 4800 away from 5009, we end up with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Let's proceed to step 9:
If we divide 2090 by 960, we get 2 and a remainder of 170.
The number 2 becomes the next digit in our result. 
Result so far: 29245.2
If we take 1920 away from 2090, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 10:
1700 divided by 960 is 1 with a remainder of 740.
The number 1 becomes the next digit in our result. 
Result so far: 29245.21
Subtracting 960 from 1700 leaves us with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Advancing to step 11:
The number 960 fits into 7400 7 times, leaving a remainder of 680.
Put 7 as the next digit of the answer. 
Result so far: 29245.217
The remainder is 680 after subtracting 6720 from 7400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Going ahead to step 12:
960 goes into 6800 7 times with a remainder of 80.
Use 7 as the next digit of our solution. 
Result so far: 29245.2177
Subtracting 6720 from 6800 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final outcome is 29245.2177, with a leftover of 0.0008.
