27128260 divided by 904 
The aim is to understand the frequency of 904 in 27128260.

Moving on to step 1:
2 divided by 904 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 904

On to step 2:
The number 904 fits into 27 0 times, leaving a remainder of 27.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 27, we end up with 27.
Include the next digit (1) from the dividend after 27, then repeat: 271 / 904

Step 3:
The number 904 fits into 271 0 times, leaving a remainder of 271.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 271 and we're left with 271.
Include the next digit (2) from the dividend after 271, then repeat: 2712 / 904

Step 4:
The number 904 fits into 2712 3 times, leaving a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 2712 from 2712 and we're left with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 904

Let's proceed to step 5:
8 divided by 904 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 30.0
If we subtract 0 from 8, we get 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 904

Going ahead to step 6:
904 goes into 82 0 times with a remainder of 82.
Use 0 as the next digit of our solution. 
Result so far: 300.0
If we subtract 0 from 82, we get 82.
Include the next digit (6) from the dividend after 82, then repeat: 826 / 904

Advancing to step 7:
826 divided by 904 is 0 with a remainder of 826.
The next digit of our result is 0. 
Result so far: 3000.0
Deduct 0 from 826 and we're left with 826.
Grab the next digit (0) from the dividend, add it to 826, then carry on: 8260 / 904

On to step 8:
904 goes into 8260 9 times with a remainder of 124.
Put 9 as the next digit of the answer. 
Result so far: 30009.0
Deduct 8136 from 8260 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 9:
904 can be fit into 1240 1 times, resulting in a remainder of 336.
Use 1 as the next digit of our solution. 
Result so far: 30009.1
The remainder is 336 after subtracting 904 from 1240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Let's proceed to step 10:
904 can be fit into 3360 3 times, resulting in a remainder of 648.
Put 3 as the next digit of the answer. 
Result so far: 30009.13
Deduct 2712 from 3360 and we're left with 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

On to step 11:
If we divide 6480 by 904, we get 7 and a remainder of 152.
Record the quotient 7 as the next digit in the result. 
Result so far: 30009.137
Deduct 6328 from 6480 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 12:
The number 904 fits into 1520 1 times, leaving a remainder of 616.
The next digit of our result is 1. 
Result so far: 30009.1371
Deduct 904 from 1520 and we're left with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Going ahead to step 13:
When dividing 6160 by 904, we get 6 with a remainder of 736.
Record the quotient 6 as the next digit in the result. 
Result so far: 30009.13716
Subtracting 5424 from 6160 leaves us with 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Let's proceed to step 14:
When dividing 7360 by 904, we get 8 with a remainder of 128.
The next digit of our result is 8. 
Result so far: 30009.137168
The remainder is 128 after subtracting 7232 from 7360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 15:
The number 904 fits into 1280 1 times, leaving a remainder of 376.
Put 1 as the next digit of the answer. 
Result so far: 30009.1371681
Subtract 904 from 1280 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Let's proceed to step 16:
The number 904 fits into 3760 4 times, leaving a remainder of 144.
Record the quotient 4 as the next digit in the result. 
Result so far: 30009.13716814
If we subtract 3616 from 3760, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

The final outcome is 30009.13716814, with a leftover of 1.44e-07.
