We're dividing 28972045 by 879 
The aim is to understand the frequency of 879 in 28972045.

Moving on to step 1:
879 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 879

Let's proceed to step 2:
879 can be fit into 28 0 times, resulting in a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Grab the next digit (9) from the dividend, add it to 28, then carry on: 289 / 879

Advancing to step 3:
879 goes into 289 0 times with a remainder of 289.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 289 and we're left with 289.
Include the next digit (7) from the dividend after 289, then repeat: 2897 / 879

Moving on to step 4:
879 can be fit into 2897 3 times, resulting in a remainder of 260.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 2637 from 2897 leaves us with 260.
Grab the next digit (2) from the dividend, add it to 260, then carry on: 2602 / 879

Step 5:
879 can be fit into 2602 2 times, resulting in a remainder of 844.
The next digit of our result is 2. 
Result so far: 32.0
The remainder is 844 after subtracting 1758 from 2602.
Take the next digit (0) from the dividend and append it to 844, then repeat: 8440 / 879

Moving on to step 6:
The number 879 fits into 8440 9 times, leaving a remainder of 529.
The number 9 becomes the next digit in our result. 
Result so far: 329.0
If we subtract 7911 from 8440, we get 529.
Bring next digit (4) of the dividend behind the 529 and repeat the process: 5294 / 879

Going ahead to step 7:
5294 divided by 879 is 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 3296.0
If we take 5274 away from 5294, we end up with 20.
Grab the next digit (5) from the dividend, add it to 20, then carry on: 205 / 879

Advancing to step 8:
When dividing 205 by 879, we get 0 with a remainder of 205.
Write down 0 as next digit of the result. 
Result so far: 32960.0
The remainder is 205 after subtracting 0 from 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Going ahead to step 9:
2050 divided by 879 is 2 with a remainder of 292.
The next digit of our result is 2. 
Result so far: 32960.2
Deduct 1758 from 2050 and we're left with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

On to step 10:
879 can be fit into 2920 3 times, resulting in a remainder of 283.
Put 3 as the next digit of the answer. 
Result so far: 32960.23
Subtract 2637 from 2920 to get 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

On to step 11:
879 can be fit into 2830 3 times, resulting in a remainder of 193.
Record the quotient 3 as the next digit in the result. 
Result so far: 32960.233
If we subtract 2637 from 2830, we get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

After the division, we end up with 32960.233 and a remainder of 0.0193.
