We're dividing 16862309 by 904 
The aim is to understand the frequency of 904 in 16862309.

Let's proceed to step 1:
904 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 904

Step 2:
The number 904 fits into 16 0 times, leaving a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 904

Moving on to step 3:
904 goes into 168 0 times with a remainder of 168.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 168 after subtracting 0 from 168.
Append the next digit (6) from the dividend to 168 and continue with: 1686 / 904

On to step 4:
When dividing 1686 by 904, we get 1 with a remainder of 782.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 904 from 1686 leaves us with 782.
Grab the next digit (2) from the dividend, add it to 782, then carry on: 7822 / 904

Moving on to step 5:
904 goes into 7822 8 times with a remainder of 590.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtract 7232 from 7822 to get 590.
Grab the next digit (3) from the dividend, add it to 590, then carry on: 5903 / 904

Let's proceed to step 6:
5903 divided by 904 is 6 with a remainder of 479.
Use 6 as the next digit of our solution. 
Result so far: 186.0
The remainder is 479 after subtracting 5424 from 5903.
Grab the next digit (0) from the dividend, add it to 479, then carry on: 4790 / 904

Moving on to step 7:
904 goes into 4790 5 times with a remainder of 270.
The number 5 becomes the next digit in our result. 
Result so far: 1865.0
If we subtract 4520 from 4790, we get 270.
Append the next digit (9) from the dividend to 270 and continue with: 2709 / 904

Step 8:
When dividing 2709 by 904, we get 2 with a remainder of 901.
Write down 2 as next digit of the result. 
Result so far: 18652.0
If we take 1808 away from 2709, we end up with 901.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9010, and continue the process.

On to step 9:
When dividing 9010 by 904, we get 9 with a remainder of 874.
Use 9 as the next digit of our solution. 
Result so far: 18652.9
If we subtract 8136 from 9010, we get 874.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8740, and continue the process.

Step 10:
904 goes into 8740 9 times with a remainder of 604.
Use 9 as the next digit of our solution. 
Result so far: 18652.99
Subtract 8136 from 8740 to get 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

The final result is 18652.99 with a remainder of 0.604.
