We look at the division of 27087079 by 880 
The aim is to understand the frequency of 880 in 27087079.

Let's proceed to step 1:
If we divide 2 by 880, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 880

Let's proceed to step 2:
If we divide 27 by 880, we get 0 and a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 27 and we're left with 27.
Fetch the next digit (0) from the dividend, attach it to 27 and continue: 270 / 880

Going ahead to step 3:
When dividing 270 by 880, we get 0 with a remainder of 270.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 270, we end up with 270.
Fetch the next digit (8) from the dividend, attach it to 270 and continue: 2708 / 880

Let's proceed to step 4:
880 can be fit into 2708 3 times, resulting in a remainder of 68.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 2640 from 2708, we get 68.
Fetch the next digit (7) from the dividend, attach it to 68 and continue: 687 / 880

Advancing to step 5:
The number 880 fits into 687 0 times, leaving a remainder of 687.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Subtracting 0 from 687 leaves us with 687.
Append the next digit (0) from the dividend to 687 and continue with: 6870 / 880

Going ahead to step 6:
When dividing 6870 by 880, we get 7 with a remainder of 710.
The next digit of our result is 7. 
Result so far: 307.0
If we take 6160 away from 6870, we end up with 710.
Append the next digit (7) from the dividend to 710 and continue with: 7107 / 880

Let's proceed to step 7:
If we divide 7107 by 880, we get 8 and a remainder of 67.
The next digit of our result is 8. 
Result so far: 3078.0
If we subtract 7040 from 7107, we get 67.
Include the next digit (9) from the dividend after 67, then repeat: 679 / 880

Let's proceed to step 8:
When dividing 679 by 880, we get 0 with a remainder of 679.
The number 0 becomes the next digit in our result. 
Result so far: 30780.0
The remainder is 679 after subtracting 0 from 679.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

Advancing to step 9:
If we divide 6790 by 880, we get 7 and a remainder of 630.
Write down 7 as next digit of the result. 
Result so far: 30780.7
Subtract 6160 from 6790 to get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Step 10:
If we divide 6300 by 880, we get 7 and a remainder of 140.
Use 7 as the next digit of our solution. 
Result so far: 30780.77
Subtracting 6160 from 6300 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Our division results in 30780.77 with a remaining 0.14.
