We look at the division of 3118048 by 863 
The aim is to understand the frequency of 863 in 3118048.

On to step 1:
3 divided by 863 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 863

Let's proceed to step 2:
When dividing 31 by 863, we get 0 with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Bring next digit (1) of the dividend behind the 31 and repeat the process: 311 / 863

Step 3:
311 divided by 863 is 0 with a remainder of 311.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 311, we end up with 311.
Fetch the next digit (8) from the dividend, attach it to 311 and continue: 3118 / 863

Step 4:
863 goes into 3118 3 times with a remainder of 529.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 529 after subtracting 2589 from 3118.
Include the next digit (0) from the dividend after 529, then repeat: 5290 / 863

Step 5:
When dividing 5290 by 863, we get 6 with a remainder of 112.
Write down 6 as next digit of the result. 
Result so far: 36.0
If we take 5178 away from 5290, we end up with 112.
Take the next digit (4) from the dividend and append it to 112, then repeat: 1124 / 863

Step 6:
When dividing 1124 by 863, we get 1 with a remainder of 261.
Write down 1 as next digit of the result. 
Result so far: 361.0
Subtracting 863 from 1124 leaves us with 261.
Grab the next digit (8) from the dividend, add it to 261, then carry on: 2618 / 863

Step 7:
The number 863 fits into 2618 3 times, leaving a remainder of 29.
The number 3 becomes the next digit in our result. 
Result so far: 3613.0
The remainder is 29 after subtracting 2589 from 2618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 8:
When dividing 290 by 863, we get 0 with a remainder of 290.
Use 0 as the next digit of our solution. 
Result so far: 3613.0
If we take 0 away from 290, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 9:
863 can be fit into 2900 3 times, resulting in a remainder of 311.
The number 3 becomes the next digit in our result. 
Result so far: 3613.03
If we take 2589 away from 2900, we end up with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Moving on to step 10:
3110 divided by 863 is 3 with a remainder of 521.
The next digit of our result is 3. 
Result so far: 3613.033
Deduct 2589 from 3110 and we're left with 521.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5210, and continue the process.

The quotient of the division is 3613.033, and the remainder is 0.0521.
