We look at the division of 28683512 by 904 
The aim is to understand the frequency of 904 in 28683512.

Advancing to step 1:
904 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 904

On to step 2:
When dividing 28 by 904, we get 0 with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Fetch the next digit (6) from the dividend, attach it to 28 and continue: 286 / 904

Let's proceed to step 3:
904 goes into 286 0 times with a remainder of 286.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 286 and we're left with 286.
Bring next digit (8) of the dividend behind the 286 and repeat the process: 2868 / 904

Let's proceed to step 4:
904 can be fit into 2868 3 times, resulting in a remainder of 156.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 2712 from 2868, we get 156.
Grab the next digit (3) from the dividend, add it to 156, then carry on: 1563 / 904

On to step 5:
When dividing 1563 by 904, we get 1 with a remainder of 659.
The next digit of our result is 1. 
Result so far: 31.0
Subtract 904 from 1563 to get 659.
Include the next digit (5) from the dividend after 659, then repeat: 6595 / 904

On to step 6:
904 goes into 6595 7 times with a remainder of 267.
Write down 7 as next digit of the result. 
Result so far: 317.0
Subtracting 6328 from 6595 leaves us with 267.
Take the next digit (1) from the dividend and append it to 267, then repeat: 2671 / 904

Step 7:
2671 divided by 904 is 2 with a remainder of 863.
Write down 2 as next digit of the result. 
Result so far: 3172.0
Deduct 1808 from 2671 and we're left with 863.
Fetch the next digit (2) from the dividend, attach it to 863 and continue: 8632 / 904

Let's proceed to step 8:
If we divide 8632 by 904, we get 9 and a remainder of 496.
Use 9 as the next digit of our solution. 
Result so far: 31729.0
If we take 8136 away from 8632, we end up with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

On to step 9:
904 can be fit into 4960 5 times, resulting in a remainder of 440.
Use 5 as the next digit of our solution. 
Result so far: 31729.5
Subtract 4520 from 4960 to 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.

Step 10:
904 goes into 4400 4 times with a remainder of 784.
The next digit of our result is 4. 
Result so far: 31729.54
The remainder is 784 after subtracting 3616 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

Advancing to step 11:
If we divide 7840 by 904, we get 8 and a remainder of 608.
The next digit of our result is 8. 
Result so far: 31729.548
The remainder is 608 after subtracting 7232 from 7840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Advancing to step 12:
The number 904 fits into 6080 6 times, leaving a remainder of 656.
Put 6 as the next digit of the answer. 
Result so far: 31729.5486
Subtract 5424 from 6080 to get 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

On to step 13:
When dividing 6560 by 904, we get 7 with a remainder of 232.
Record the quotient 7 as the next digit in the result. 
Result so far: 31729.54867
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.

Step 14:
If we divide 2320 by 904, we get 2 and a remainder of 512.
The next digit of our result is 2. 
Result so far: 31729.548672
Subtracting 1808 from 2320 leaves us with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

On to step 15:
904 goes into 5120 5 times with a remainder of 600.
Write down 5 as next digit of the result. 
Result so far: 31729.5486725
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.

Going ahead to step 16:
If we divide 6000 by 904, we get 6 and a remainder of 576.
Use 6 as the next digit of our solution. 
Result so far: 31729.54867256
Deduct 5424 from 6000 and we're left 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.

The quotient of the division is 31729.54867256, and the remainder is 5.76e-07.
