45864667 divided by 855 
The aim is to understand the frequency of 855 in 45864667.

On to step 1:
The number 855 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 855

Advancing to step 2:
The number 855 fits into 45 0 times, leaving a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Bring next digit (8) of the dividend behind the 45 and repeat the process: 458 / 855

Going ahead to step 3:
458 divided by 855 is 0 with a remainder of 458.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 458, we get 458.
Grab the next digit (6) from the dividend, add it to 458, then carry on: 4586 / 855

Advancing to step 4:
If we divide 4586 by 855, we get 5 and a remainder of 311.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 311 after subtracting 4275 from 4586.
Bring next digit (4) of the dividend behind the 311 and repeat the process: 3114 / 855

On to step 5:
3114 divided by 855 is 3 with a remainder of 549.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
If we subtract 2565 from 3114, we get 549.
Grab the next digit (6) from the dividend, add it to 549, then carry on: 5496 / 855

Step 6:
When dividing 5496 by 855, we get 6 with a remainder of 366.
The number 6 becomes the next digit in our result. 
Result so far: 536.0
Deduct 5130 from 5496 and we're left with 366.
Grab the next digit (6) from the dividend, add it to 366, then carry on: 3666 / 855

Moving on to step 7:
If we divide 3666 by 855, we get 4 and a remainder of 246.
The number 4 becomes the next digit in our result. 
Result so far: 5364.0
Deduct 3420 from 3666 and we're left with 246.
Fetch the next digit (7) from the dividend, attach it to 246 and continue: 2467 / 855

Step 8:
If we divide 2467 by 855, we get 2 and a remainder of 757.
Put 2 as the next digit of the answer. 
Result so far: 53642.0
If we take 1710 away from 2467, we end up with 757.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7570, and continue the process.

Step 9:
7570 divided by 855 is 8 with a remainder of 730.
Record the quotient 8 as the next digit in the result. 
Result so far: 53642.8
Subtract 6840 from 7570 to get 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Step 10:
When dividing 7300 by 855, we get 8 with a remainder of 460.
The next digit of our result is 8. 
Result so far: 53642.88
If we take 6840 away from 7300, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

The final outcome is 53642.88, with a leftover of 0.46.
