Let's divide 2256721 by 880
The aim is to understand the frequency of 880 in 2256721.

Advancing to step 1:
The number 880 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 subtract 0 from 2, we get 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 880

Going ahead to step 2:
When dividing 22 by 880, we get 0 with a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 22 and we're left with 22.
Grab the next digit (5) from the dividend, add it to 22, then carry on: 225 / 880

Moving on to step 3:
225 divided by 880 is 0 with a remainder of 225.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 225 after subtracting 0 from 225.
Bring next digit (6) of the dividend behind the 225 and repeat the process: 2256 / 880

Advancing to step 4:
880 can be fit into 2256 2 times, resulting in a remainder of 496.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 1760 from 2256 and we're left with 496.
Bring next digit (7) of the dividend behind the 496 and repeat the process: 4967 / 880

Advancing to step 5:
If we divide 4967 by 880, we get 5 and a remainder of 567.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtracting 4400 from 4967 leaves us with 567.
Fetch the next digit (2) from the dividend, attach it to 567 and continue: 5672 / 880

Going ahead to step 6:
If we divide 5672 by 880, we get 6 and a remainder of 392.
The number 6 becomes the next digit in our result. 
Result so far: 256.0
If we subtract 5280 from 5672, we get 392.
Grab the next digit (1) from the dividend, add it to 392, then carry on: 3921 / 880

On to step 7:
When dividing 3921 by 880, we get 4 with a remainder of 401.
Put 4 as the next digit of the answer. 
Result so far: 2564.0
The remainder is 401 after subtracting 3520 from 3921.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Let's proceed to step 8:
880 goes into 4010 4 times with a remainder of 490.
Put 4 as the next digit of the answer. 
Result so far: 2564.4
Deduct 3520 from 4010 and we're left with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Step 9:
4900 divided by 880 is 5 with a remainder of 500.
The number 5 becomes the next digit in our result. 
Result so far: 2564.45
Subtract 4400 from 4900 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Moving on to step 10:
The number 880 fits into 5000 5 times, leaving a remainder of 600.
The next digit of our result is 5. 
Result so far: 2564.455
If we subtract 4400 from 5000, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The final result is 2564.455 with a remainder of 0.06.
