We look at the division of 33387604 by 904 
The aim is to understand the frequency of 904 in 33387604.

Advancing to step 1:
3 divided by 904 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 904

Advancing to step 2:
The number 904 fits into 33 0 times, leaving a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 33 and we're left with 33.
Bring next digit (3) of the dividend behind the 33 and repeat the process: 333 / 904

On to step 3:
If we divide 333 by 904, we get 0 and a remainder of 333.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 333 leaves us with 333.
Bring next digit (8) of the dividend behind the 333 and repeat the process: 3338 / 904

Advancing to step 4:
The number 904 fits into 3338 3 times, leaving a remainder of 626.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 2712 from 3338, we get 626.
Append the next digit (7) from the dividend to 626 and continue with: 6267 / 904

Let's proceed to step 5:
6267 divided by 904 is 6 with a remainder of 843.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
If we subtract 5424 from 6267, we get 843.
Grab the next digit (6) from the dividend, add it to 843, then carry on: 8436 / 904

Going ahead to step 6:
904 can be fit into 8436 9 times, resulting in a remainder of 300.
Use 9 as the next digit of our solution. 
Result so far: 369.0
Subtracting 8136 from 8436 leaves us with 300.
Grab the next digit (0) from the dividend, add it to 300, then carry on: 3000 / 904

On to step 7:
904 goes into 3000 3 times with a remainder of 288.
Write down 3 as next digit of the result. 
Result so far: 3693.0
If we subtract 2712 from 3000, we get 288.
Grab the next digit (4) from the dividend, add it to 288, then carry on: 2884 / 904

On to step 8:
904 can be fit into 2884 3 times, resulting in a remainder of 172.
Write down 3 as next digit of the result. 
Result so far: 36933.0
Subtract 2712 from 2884 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Let's proceed to step 9:
904 goes into 1720 1 times with a remainder of 816.
Record the quotient 1 as the next digit in the result. 
Result so far: 36933.1
If we take 904 away from 1720, we end up with 816.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8160, and continue the process.

Let's proceed to step 10:
The number 904 fits into 8160 9 times, leaving a remainder of 24.
The next digit of our result is 9. 
Result so far: 36933.19
Subtract 8136 from 8160 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 11:
The number 904 fits into 240 0 times, leaving a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 36933.19
If we subtract 0 from 240, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 12:
The number 904 fits into 2400 2 times, leaving a remainder of 592.
The next digit of our result is 2. 
Result so far: 36933.1902
The remainder is 592 after subtracting 1808 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Step 13:
The number 904 fits into 5920 6 times, leaving a remainder of 496.
Record the quotient 6 as the next digit in the result. 
Result so far: 36933.19026
The remainder is 496 after subtracting 5424 from 5920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Let's proceed to step 14:
904 goes into 4960 5 times with a remainder of 440.
Record the quotient 5 as the next digit in the result. 
Result so far: 36933.190265
Deduct 4520 from 4960 and we're left with 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 15:
904 goes into 4400 4 times with a remainder of 784.
Write down 4 as next digit of the result. 
Result so far: 36933.1902654
Subtracting 3616 from 4400 leaves us 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.

Advancing to step 16:
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: 36933.19026548
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.

Our division results in 36933.19026548 with a remaining 6.08e-07.
