1904208 divided by 855 
The aim is to understand the frequency of 855 in 1904208.

Advancing to step 1:
855 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 855

Let's proceed to step 2:
If we divide 19 by 855, we get 0 and a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Append the next digit (0) from the dividend to 19 and continue with: 190 / 855

On to step 3:
The number 855 fits into 190 0 times, leaving a remainder of 190.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 190, we get 190.
Include the next digit (4) from the dividend after 190, then repeat: 1904 / 855

Moving on to step 4:
1904 divided by 855 is 2 with a remainder of 194.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 1710 from 1904, we get 194.
Grab the next digit (2) from the dividend, add it to 194, then carry on: 1942 / 855

On to step 5:
When dividing 1942 by 855, we get 2 with a remainder of 232.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we take 1710 away from 1942, we end up with 232.
Append the next digit (0) from the dividend to 232 and continue with: 2320 / 855

On to step 6:
If we divide 2320 by 855, we get 2 and a remainder of 610.
Use 2 as the next digit of our solution. 
Result so far: 222.0
Subtracting 1710 from 2320 leaves us with 610.
Take the next digit (8) from the dividend and append it to 610, then repeat: 6108 / 855

Advancing to step 7:
The number 855 fits into 6108 7 times, leaving a remainder of 123.
The next digit of our result is 7. 
Result so far: 2227.0
The remainder is 123 after subtracting 5985 from 6108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

On to step 8:
855 goes into 1230 1 times with a remainder of 375.
Write down 1 as next digit of the result. 
Result so far: 2227.1
Subtracting 855 from 1230 leaves us with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Step 9:
The number 855 fits into 3750 4 times, leaving a remainder of 330.
The next digit of our result is 4. 
Result so far: 2227.14
The remainder is 330 after subtracting 3420 from 3750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 10:
If we divide 3300 by 855, we get 3 and a remainder of 735.
Record the quotient 3 as the next digit in the result. 
Result so far: 2227.143
If we subtract 2565 from 3300, we get 735.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

On to step 11:
The number 855 fits into 7350 8 times, leaving a remainder of 510.
Put 8 as the next digit of the answer. 
Result so far: 2227.1438
Subtracting 6840 from 7350 leaves us with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Let's proceed to step 12:
If we divide 5100 by 855, we get 5 and a remainder of 825.
Put 5 as the next digit of the answer. 
Result so far: 2227.14385
If we subtract 4275 from 5100, we get 825.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8250, and continue the process.

Moving on to step 13:
855 can be fit into 8250 9 times, resulting in a remainder of 555.
The next digit of our result is 9. 
Result so far: 2227.143859
Deduct 7695 from 8250 and we're left with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Step 14:
If we divide 5550 by 855, we get 6 and a remainder of 420.
Record the quotient 6 as the next digit in the result. 
Result so far: 2227.1438596
The remainder is 420 after subtracting 5130 from 5550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 15:
4200 divided by 855 is 4 with a remainder of 780.
Write down 4 as next digit of the result. 
Result so far: 2227.14385964
If we subtract 3420 from 4200, we get 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

The final result is 2227.14385964 with a remainder of 7.8e-07.
