We look at the division of 280902 by 102 
The aim is to understand the frequency of 102 in 280902.

Let's proceed to step 1:
The number 102 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 102

Step 2:
28 divided by 102 is 0 with a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Append the next digit (0) from the dividend to 28 and continue with: 280 / 102

On to step 3:
102 goes into 280 2 times with a remainder of 76.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 204 from 280 leaves us with 76.
Grab the next digit (9) from the dividend, add it to 76, then carry on: 769 / 102

Step 4:
The number 102 fits into 769 7 times, leaving a remainder of 55.
Put 7 as the next digit of the answer. 
Result so far: 27.0
Deduct 714 from 769 and we're left with 55.
Fetch the next digit (0) from the dividend, attach it to 55 and continue: 550 / 102

Let's proceed to step 5:
102 can be fit into 550 5 times, resulting in a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 275.0
Deduct 510 from 550 and we're left with 40.
Append the next digit (2) from the dividend to 40 and continue with: 402 / 102

Advancing to step 6:
102 can be fit into 402 3 times, resulting in a remainder of 96.
Write down 3 as next digit of the result. 
Result so far: 2753.0
Subtract 306 from 402 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 7:
102 goes into 960 9 times with a remainder of 42.
Write down 9 as next digit of the result. 
Result so far: 2753.9
The remainder is 42 after subtracting 918 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 8:
102 goes into 420 4 times with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 2753.94
Deduct 408 from 420 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 9:
102 goes into 120 1 times with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 2753.941
Subtract 102 from 120 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 10:
180 divided by 102 is 1 with a remainder of 78.
Write down 1 as next digit of the result. 
Result so far: 2753.9411
Subtracting 102 from 180 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

In conclusion, the division gives 2753.9411 with a balance of 0.00078.
