We're dividing 36117621 by 855 
The aim is to understand the frequency of 855 in 36117621.

Step 1:
855 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 855

On to step 2:
855 goes into 36 0 times with a remainder of 36.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 36, we end up with 36.
Include the next digit (1) from the dividend after 36, then repeat: 361 / 855

Step 3:
855 goes into 361 0 times with a remainder of 361.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 361, we end up with 361.
Grab the next digit (1) from the dividend, add it to 361, then carry on: 3611 / 855

Going ahead to step 4:
When dividing 3611 by 855, we get 4 with a remainder of 191.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 191 after subtracting 3420 from 3611.
Append the next digit (7) from the dividend to 191 and continue with: 1917 / 855

Going ahead to step 5:
855 goes into 1917 2 times with a remainder of 207.
Put 2 as the next digit of the answer. 
Result so far: 42.0
If we subtract 1710 from 1917, we get 207.
Include the next digit (6) from the dividend after 207, then repeat: 2076 / 855

Advancing to step 6:
If we divide 2076 by 855, we get 2 and a remainder of 366.
Put 2 as the next digit of the answer. 
Result so far: 422.0
Subtracting 1710 from 2076 leaves us with 366.
Append the next digit (2) from the dividend to 366 and continue with: 3662 / 855

Going ahead to step 7:
When dividing 3662 by 855, we get 4 with a remainder of 242.
Record the quotient 4 as the next digit in the result. 
Result so far: 4224.0
Subtracting 3420 from 3662 leaves us with 242.
Include the next digit (1) from the dividend after 242, then repeat: 2421 / 855

Going ahead to step 8:
If we divide 2421 by 855, we get 2 and a remainder of 711.
The next digit of our result is 2. 
Result so far: 42242.0
The remainder is 711 after subtracting 1710 from 2421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7110, and continue the process.

Going ahead to step 9:
855 goes into 7110 8 times with a remainder of 270.
Put 8 as the next digit of the answer. 
Result so far: 42242.8
Subtract 6840 from 7110 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 10:
The number 855 fits into 2700 3 times, leaving a remainder of 135.
Use 3 as the next digit of our solution. 
Result so far: 42242.83
If we subtract 2565 from 2700, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Moving on to step 11:
The number 855 fits into 1350 1 times, leaving a remainder of 495.
Use 1 as the next digit of our solution. 
Result so far: 42242.831
The remainder is 495 after subtracting 855 from 1350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Going ahead to step 12:
855 can be fit into 4950 5 times, resulting in a remainder of 675.
The next digit of our result is 5. 
Result so far: 42242.8315
The remainder is 675 after subtracting 4275 from 4950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Moving on to step 13:
6750 divided by 855 is 7 with a remainder of 765.
The next digit of our result is 7. 
Result so far: 42242.83157
Subtracting 5985 from 6750 leaves us with 765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7650, and continue the process.

Advancing to step 14:
855 goes into 7650 8 times with a remainder of 810.
The number 8 becomes the next digit in our result. 
Result so far: 42242.831578
If we subtract 6840 from 7650, we get 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Going ahead to step 15:
If we divide 8100 by 855, we get 9 and a remainder of 405.
The number 9 becomes the next digit in our result. 
Result so far: 42242.8315789
If we take 7695 away from 8100, we end up with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Advancing to step 16:
The number 855 fits into 4050 4 times, leaving a remainder of 630.
Use 4 as the next digit of our solution. 
Result so far: 42242.83157894
The remainder is 630 after subtracting 3420 from 4050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

The quotient of the division is 42242.83157894, and the remainder is 6.3e-07.
