86623012 divided by 880 
The aim is to understand the frequency of 880 in 86623012.

Let's proceed to step 1:
8 divided by 880 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 880

Step 2:
880 can be fit into 86 0 times, resulting in a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Append the next digit (6) from the dividend to 86 and continue with: 866 / 880

Advancing to step 3:
880 can be fit into 866 0 times, resulting in a remainder of 866.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 866 to get 866.
Bring next digit (2) of the dividend behind the 866 and repeat the process: 8662 / 880

Going ahead to step 4:
When dividing 8662 by 880, we get 9 with a remainder of 742.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 742 after subtracting 7920 from 8662.
Append the next digit (3) from the dividend to 742 and continue with: 7423 / 880

Moving on to step 5:
The number 880 fits into 7423 8 times, leaving a remainder of 383.
Put 8 as the next digit of the answer. 
Result so far: 98.0
The remainder is 383 after subtracting 7040 from 7423.
Bring next digit (0) of the dividend behind the 383 and repeat the process: 3830 / 880

Advancing to step 6:
If we divide 3830 by 880, we get 4 and a remainder of 310.
Use 4 as the next digit of our solution. 
Result so far: 984.0
Subtract 3520 from 3830 to get 310.
Include the next digit (1) from the dividend after 310, then repeat: 3101 / 880

Step 7:
If we divide 3101 by 880, we get 3 and a remainder of 461.
The number 3 becomes the next digit in our result. 
Result so far: 9843.0
Subtracting 2640 from 3101 leaves us with 461.
Grab the next digit (2) from the dividend, add it to 461, then carry on: 4612 / 880

Moving on to step 8:
When dividing 4612 by 880, we get 5 with a remainder of 212.
The number 5 becomes the next digit in our result. 
Result so far: 98435.0
Subtract 4400 from 4612 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

On to step 9:
When dividing 2120 by 880, we get 2 with a remainder of 360.
Put 2 as the next digit of the answer. 
Result so far: 98435.2
If we take 1760 away from 2120, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 10:
880 can be fit into 3600 4 times, resulting in a remainder of 80.
Use 4 as the next digit of our solution. 
Result so far: 98435.24
If we take 3520 away from 3600, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 11:
When dividing 800 by 880, we get 0 with a remainder of 800.
Record the quotient 0 as the next digit in the result. 
Result so far: 98435.24
Subtracting 0 from 800 leaves us with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Step 12:
The number 880 fits into 8000 9 times, leaving a remainder of 80.
Put 9 as the next digit of the answer. 
Result so far: 98435.2409
Subtract 7920 from 8000 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 13:
880 goes into 800 0 times with a remainder of 800.
The next digit of our result is 0. 
Result so far: 98435.2409
The remainder is 800 after subtracting 0 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Moving on to step 14:
880 can be fit into 8000 9 times, resulting in a remainder of 80.
Put 9 as the next digit of the answer. 
Result so far: 98435.240909
The remainder is 80 after subtracting 7920 from 8000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 15:
When dividing 800 by 880, we get 0 with a remainder of 800.
Write down 0 as next digit of the result. 
Result so far: 98435.240909
Deduct 0 from 800 and we're left with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Step 16:
When dividing 8000 by 880, we get 9 with a remainder of 80.
The next digit of our result is 9. 
Result so far: 98435.24090909
If we subtract 7920 from 8000, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The quotient of the division is 98435.24090909, and the remainder is 8e-08.
