We look at the division of 55882808 by 863 
The aim is to understand the frequency of 863 in 55882808.

Going ahead to step 1:
863 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 863

Advancing to step 2:
863 goes into 55 0 times with a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Include the next digit (8) from the dividend after 55, then repeat: 558 / 863

Going ahead to step 3:
863 can be fit into 558 0 times, resulting in a remainder of 558.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 558, we end up with 558.
Grab the next digit (8) from the dividend, add it to 558, then carry on: 5588 / 863

Let's proceed to step 4:
The number 863 fits into 5588 6 times, leaving a remainder of 410.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 5178 from 5588, we get 410.
Include the next digit (2) from the dividend after 410, then repeat: 4102 / 863

Advancing to step 5:
When dividing 4102 by 863, we get 4 with a remainder of 650.
Use 4 as the next digit of our solution. 
Result so far: 64.0
Subtract 3452 from 4102 to get 650.
Bring next digit (8) of the dividend behind the 650 and repeat the process: 6508 / 863

On to step 6:
The number 863 fits into 6508 7 times, leaving a remainder of 467.
Write down 7 as next digit of the result. 
Result so far: 647.0
If we subtract 6041 from 6508, we get 467.
Fetch the next digit (0) from the dividend, attach it to 467 and continue: 4670 / 863

Advancing to step 7:
When dividing 4670 by 863, we get 5 with a remainder of 355.
Put 5 as the next digit of the answer. 
Result so far: 6475.0
Subtracting 4315 from 4670 leaves us with 355.
Include the next digit (8) from the dividend after 355, then repeat: 3558 / 863

Going ahead to step 8:
When dividing 3558 by 863, we get 4 with a remainder of 106.
Write down 4 as next digit of the result. 
Result so far: 64754.0
If we subtract 3452 from 3558, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 9:
When dividing 1060 by 863, we get 1 with a remainder of 197.
The number 1 becomes the next digit in our result. 
Result so far: 64754.1
The remainder is 197 after subtracting 863 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

On to step 10:
863 goes into 1970 2 times with a remainder of 244.
Write down 2 as next digit of the result. 
Result so far: 64754.12
If we take 1726 away from 1970, we end up with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Going ahead to step 11:
2440 divided by 863 is 2 with a remainder of 714.
Record the quotient 2 as the next digit in the result. 
Result so far: 64754.122
Subtract 1726 from 2440 to get 714.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7140, and continue the process.

The final result is 64754.122 with a remainder of 0.0714.
