15760606 ÷ 880 
The aim is to understand the frequency of 880 in 15760606.

Moving on to step 1:
880 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 880

Let's proceed to step 2:
15 divided by 880 is 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Include the next digit (7) from the dividend after 15, then repeat: 157 / 880

Step 3:
When dividing 157 by 880, we get 0 with a remainder of 157.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 157 after subtracting 0 from 157.
Fetch the next digit (6) from the dividend, attach it to 157 and continue: 1576 / 880

On to step 4:
1576 divided by 880 is 1 with a remainder of 696.
The next digit of our result is 1. 
Result so far: 1.0
If we take 880 away from 1576, we end up with 696.
Append the next digit (0) from the dividend to 696 and continue with: 6960 / 880

Moving on to step 5:
When dividing 6960 by 880, we get 7 with a remainder of 800.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Deduct 6160 from 6960 and we're left with 800.
Fetch the next digit (6) from the dividend, attach it to 800 and continue: 8006 / 880

Moving on to step 6:
The number 880 fits into 8006 9 times, leaving a remainder of 86.
Use 9 as the next digit of our solution. 
Result so far: 179.0
Deduct 7920 from 8006 and we're left with 86.
Include the next digit (0) from the dividend after 86, then repeat: 860 / 880

Going ahead to step 7:
880 can be fit into 860 0 times, resulting in a remainder of 860.
The next digit of our result is 0. 
Result so far: 1790.0
Subtracting 0 from 860 leaves us with 860.
Include the next digit (6) from the dividend after 860, then repeat: 8606 / 880

Step 8:
When dividing 8606 by 880, we get 9 with a remainder of 686.
Use 9 as the next digit of our solution. 
Result so far: 17909.0
Subtract 7920 from 8606 to get 686.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

Advancing to step 9:
880 goes into 6860 7 times with a remainder of 700.
The number 7 becomes the next digit in our result. 
Result so far: 17909.7
Deduct 6160 from 6860 and we're left with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Going ahead to step 10:
The number 880 fits into 7000 7 times, leaving a remainder of 840.
Use 7 as the next digit of our solution. 
Result so far: 17909.77
If we subtract 6160 from 7000, we get 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

After the division, we end up with 17909.77 and a remainder of 0.84.
