We look at the division of 45810077 by 855 
The aim is to understand the frequency of 855 in 45810077.

Moving on to step 1:
When dividing 4 by 855, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 855

Going ahead to step 2:
855 can be fit into 45 0 times, resulting in a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Fetch the next digit (8) from the dividend, attach it to 45 and continue: 458 / 855

Going ahead to step 3:
855 can be fit into 458 0 times, resulting in a remainder of 458.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 458 after subtracting 0 from 458.
Take the next digit (1) from the dividend and append it to 458, then repeat: 4581 / 855

Step 4:
4581 divided by 855 is 5 with a remainder of 306.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 4275 from 4581 leaves us with 306.
Take the next digit (0) from the dividend and append it to 306, then repeat: 3060 / 855

Advancing to step 5:
855 can be fit into 3060 3 times, resulting in a remainder of 495.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
If we take 2565 away from 3060, we end up with 495.
Fetch the next digit (0) from the dividend, attach it to 495 and continue: 4950 / 855

On to step 6:
When dividing 4950 by 855, we get 5 with a remainder of 675.
Use 5 as the next digit of our solution. 
Result so far: 535.0
Deduct 4275 from 4950 and we're left with 675.
Grab the next digit (7) from the dividend, add it to 675, then carry on: 6757 / 855

Let's proceed to step 7:
The number 855 fits into 6757 7 times, leaving a remainder of 772.
The number 7 becomes the next digit in our result. 
Result so far: 5357.0
Subtracting 5985 from 6757 leaves us with 772.
Fetch the next digit (7) from the dividend, attach it to 772 and continue: 7727 / 855

Going ahead to step 8:
7727 divided by 855 is 9 with a remainder of 32.
The number 9 becomes the next digit in our result. 
Result so far: 53579.0
The remainder is 32 after subtracting 7695 from 7727.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
When dividing 320 by 855, we get 0 with a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 53579.0
Deduct 0 from 320 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 10:
3200 divided by 855 is 3 with a remainder of 635.
The next digit of our result is 3. 
Result so far: 53579.03
Deduct 2565 from 3200 and we're left with 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Moving on to step 11:
6350 divided by 855 is 7 with a remainder of 365.
The number 7 becomes the next digit in our result. 
Result so far: 53579.037
Deduct 5985 from 6350 and we're left with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Step 12:
3650 divided by 855 is 4 with a remainder of 230.
Use 4 as the next digit of our solution. 
Result so far: 53579.0374
Deduct 3420 from 3650 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 13:
855 goes into 2300 2 times with a remainder of 590.
Record the quotient 2 as the next digit in the result. 
Result so far: 53579.03742
Subtracting 1710 from 2300 leaves us with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Moving on to step 14:
855 goes into 5900 6 times with a remainder of 770.
Use 6 as the next digit of our solution. 
Result so far: 53579.037426
Deduct 5130 from 5900 and we're left with 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

On to step 15:
855 goes into 7700 9 times with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 53579.0374269
Subtracting 7695 from 7700 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 16:
When dividing 50 by 855, we get 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 53579.0374269
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 53579.0374269 and a remainder of 5e-08.
