19104415 divided by 825 
The aim is to understand the frequency of 825 in 19104415.

Going ahead to step 1:
1 divided by 825 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 825

Moving on to step 2:
825 goes into 19 0 times with a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Grab the next digit (1) from the dividend, add it to 19, then carry on: 191 / 825

Let's proceed to step 3:
When dividing 191 by 825, we get 0 with a remainder of 191.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 191 after subtracting 0 from 191.
Grab the next digit (0) from the dividend, add it to 191, then carry on: 1910 / 825

On to step 4:
The number 825 fits into 1910 2 times, leaving a remainder of 260.
The next digit of our result is 2. 
Result so far: 2.0
If we take 1650 away from 1910, we end up with 260.
Grab the next digit (4) from the dividend, add it to 260, then carry on: 2604 / 825

Step 5:
825 goes into 2604 3 times with a remainder of 129.
Use 3 as the next digit of our solution. 
Result so far: 23.0
If we take 2475 away from 2604, we end up with 129.
Take the next digit (4) from the dividend and append it to 129, then repeat: 1294 / 825

Moving on to step 6:
825 can be fit into 1294 1 times, resulting in a remainder of 469.
The next digit of our result is 1. 
Result so far: 231.0
If we subtract 825 from 1294, we get 469.
Take the next digit (1) from the dividend and append it to 469, then repeat: 4691 / 825

Moving on to step 7:
825 goes into 4691 5 times with a remainder of 566.
The number 5 becomes the next digit in our result. 
Result so far: 2315.0
Subtract 4125 from 4691 to get 566.
Include the next digit (5) from the dividend after 566, then repeat: 5665 / 825

Moving on to step 8:
5665 divided by 825 is 6 with a remainder of 715.
Use 6 as the next digit of our solution. 
Result so far: 23156.0
If we take 4950 away from 5665, we end up with 715.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7150, and continue the process.

On to step 9:
825 can be fit into 7150 8 times, resulting in a remainder of 550.
The next digit of our result is 8. 
Result so far: 23156.8
Subtract 6600 from 7150 to get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Going ahead to step 10:
When dividing 5500 by 825, we get 6 with a remainder of 550.
Use 6 as the next digit of our solution. 
Result so far: 23156.86
Subtracting 4950 from 5500 leaves us with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Step 11:
5500 divided by 825 is 6 with a remainder of 550.
The number 6 becomes the next digit in our result. 
Result so far: 23156.866
Deduct 4950 from 5500 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

The quotient of the division is 23156.866, and the remainder is 0.055.
