We're dividing 18047944 by 904 
The aim is to understand the frequency of 904 in 18047944.

Step 1:
If we divide 1 by 904, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 904

Step 2:
If we divide 18 by 904, we get 0 and a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 904

Advancing to step 3:
When dividing 180 by 904, we get 0 with a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 180 to get 180.
Include the next digit (4) from the dividend after 180, then repeat: 1804 / 904

Moving on to step 4:
904 can be fit into 1804 1 times, resulting in a remainder of 900.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 904 from 1804 and we're left with 900.
Fetch the next digit (7) from the dividend, attach it to 900 and continue: 9007 / 904

Let's proceed to step 5:
The number 904 fits into 9007 9 times, leaving a remainder of 871.
The next digit of our result is 9. 
Result so far: 19.0
Subtracting 8136 from 9007 leaves us with 871.
Take the next digit (9) from the dividend and append it to 871, then repeat: 8719 / 904

Advancing to step 6:
The number 904 fits into 8719 9 times, leaving a remainder of 583.
The next digit of our result is 9. 
Result so far: 199.0
Subtract 8136 from 8719 to get 583.
Include the next digit (4) from the dividend after 583, then repeat: 5834 / 904

Step 7:
The number 904 fits into 5834 6 times, leaving a remainder of 410.
The next digit of our result is 6. 
Result so far: 1996.0
If we take 5424 away from 5834, we end up with 410.
Append the next digit (4) from the dividend to 410 and continue with: 4104 / 904

Advancing to step 8:
904 goes into 4104 4 times with a remainder of 488.
The next digit of our result is 4. 
Result so far: 19964.0
The remainder is 488 after subtracting 3616 from 4104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Advancing to step 9:
If we divide 4880 by 904, we get 5 and a remainder of 360.
Use 5 as the next digit of our solution. 
Result so far: 19964.5
If we subtract 4520 from 4880, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 10:
904 can be fit into 3600 3 times, resulting in a remainder of 888.
Put 3 as the next digit of the answer. 
Result so far: 19964.53
Subtracting 2712 from 3600 leaves us with 888.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8880, and continue the process.

Advancing to step 11:
8880 divided by 904 is 9 with a remainder of 744.
Record the quotient 9 as the next digit in the result. 
Result so far: 19964.539
If we take 8136 away from 8880, we end up with 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

Advancing to step 12:
904 goes into 7440 8 times with a remainder of 208.
The number 8 becomes the next digit in our result. 
Result so far: 19964.5398
Deduct 7232 from 7440 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 13:
The number 904 fits into 2080 2 times, leaving a remainder of 272.
Use 2 as the next digit of our solution. 
Result so far: 19964.53982
The remainder is 272 after subtracting 1808 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

On to step 14:
The number 904 fits into 2720 3 times, leaving a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 19964.539823
If we subtract 2712 from 2720, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 15:
If we divide 80 by 904, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 19964.539823
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 16:
904 goes into 800 0 times with a remainder of 800.
The next digit of our result is 0. 
Result so far: 19964.539823
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.

The final result is 19964.539823 with a remainder of 8e-07.
