We're dividing 6517884 by 904 
The aim is to understand the frequency of 904 in 6517884.

Advancing to step 1:
When dividing 6 by 904, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 904

Step 2:
904 goes into 65 0 times with a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Grab the next digit (1) from the dividend, add it to 65, then carry on: 651 / 904

On to step 3:
904 goes into 651 0 times with a remainder of 651.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 651 to get 651.
Include the next digit (7) from the dividend after 651, then repeat: 6517 / 904

Going ahead to step 4:
The number 904 fits into 6517 7 times, leaving a remainder of 189.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 189 after subtracting 6328 from 6517.
Take the next digit (8) from the dividend and append it to 189, then repeat: 1898 / 904

Advancing to step 5:
The number 904 fits into 1898 2 times, leaving a remainder of 90.
Put 2 as the next digit of the answer. 
Result so far: 72.0
The remainder is 90 after subtracting 1808 from 1898.
Include the next digit (8) from the dividend after 90, then repeat: 908 / 904

On to step 6:
The number 904 fits into 908 1 times, leaving a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 721.0
If we subtract 904 from 908, we get 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 904

Step 7:
904 can be fit into 44 0 times, resulting in a remainder of 44.
The next digit of our result is 0. 
Result so far: 7210.0
If we take 0 away from 44, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 8:
440 divided by 904 is 0 with a remainder of 440.
Use 0 as the next digit of our solution. 
Result so far: 7210.0
If we subtract 0 from 440, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 9:
4400 divided by 904 is 4 with a remainder of 784.
Record the quotient 4 as the next digit in the result. 
Result so far: 7210.04
If we take 3616 away from 4400, we end up with 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

Step 10:
904 can be fit into 7840 8 times, resulting in a remainder of 608.
Record the quotient 8 as the next digit in the result. 
Result so far: 7210.048
Subtracting 7232 from 7840 leaves us with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Moving on to step 11:
The number 904 fits into 6080 6 times, leaving a remainder of 656.
The number 6 becomes the next digit in our result. 
Result so far: 7210.0486
Deduct 5424 from 6080 and we're left with 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Advancing to step 12:
If we divide 6560 by 904, we get 7 and a remainder of 232.
The number 7 becomes the next digit in our result. 
Result so far: 7210.04867
If we subtract 6328 from 6560, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

On to step 13:
904 can be fit into 2320 2 times, resulting in a remainder of 512.
The next digit of our result is 2. 
Result so far: 7210.048672
If we subtract 1808 from 2320, we get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Going ahead to step 14:
5120 divided by 904 is 5 with a remainder of 600.
The next digit of our result is 5. 
Result so far: 7210.0486725
If we subtract 4520 from 5120, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Let's proceed to step 15:
When dividing 6000 by 904, we get 6 with a remainder of 576.
The number 6 becomes the next digit in our result. 
Result so far: 7210.04867256
If we take 5424 away from 6000, we end up with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Our division results in 7210.04867256 with a remaining 5.76e-07.
