We look at the division of 5480390 by 872 
The aim is to understand the frequency of 872 in 5480390.

On to step 1:
The number 872 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 872

On to step 2:
When dividing 54 by 872, we get 0 with a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Take the next digit (8) from the dividend and append it to 54, then repeat: 548 / 872

Let's proceed to step 3:
548 divided by 872 is 0 with a remainder of 548.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 548, we end up with 548.
Include the next digit (0) from the dividend after 548, then repeat: 5480 / 872

Going ahead to step 4:
The number 872 fits into 5480 6 times, leaving a remainder of 248.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 248 after subtracting 5232 from 5480.
Bring next digit (3) of the dividend behind the 248 and repeat the process: 2483 / 872

Going ahead to step 5:
The number 872 fits into 2483 2 times, leaving a remainder of 739.
Use 2 as the next digit of our solution. 
Result so far: 62.0
The remainder is 739 after subtracting 1744 from 2483.
Grab the next digit (9) from the dividend, add it to 739, then carry on: 7399 / 872

Step 6:
7399 divided by 872 is 8 with a remainder of 423.
The number 8 becomes the next digit in our result. 
Result so far: 628.0
Subtract 6976 from 7399 to get 423.
Take the next digit (0) from the dividend and append it to 423, then repeat: 4230 / 872

Going ahead to step 7:
4230 divided by 872 is 4 with a remainder of 742.
Write down 4 as next digit of the result. 
Result so far: 6284.0
The remainder is 742 after subtracting 3488 from 4230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7420, and continue the process.

Step 8:
872 goes into 7420 8 times with a remainder of 444.
Write down 8 as next digit of the result. 
Result so far: 6284.8
Subtracting 6976 from 7420 leaves us with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

On to step 9:
872 can be fit into 4440 5 times, resulting in a remainder of 80.
Record the quotient 5 as the next digit in the result. 
Result so far: 6284.85
Subtract 4360 from 4440 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 10:
872 goes into 800 0 times with a remainder of 800.
Use 0 as the next digit of our solution. 
Result so far: 6284.85
If we subtract 0 from 800, we get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Step 11:
The number 872 fits into 8000 9 times, leaving a remainder of 152.
Put 9 as the next digit of the answer. 
Result so far: 6284.8509
If we take 7848 away from 8000, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 12:
The number 872 fits into 1520 1 times, leaving a remainder of 648.
Use 1 as the next digit of our solution. 
Result so far: 6284.85091
Subtract 872 from 1520 to get 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

On to step 13:
6480 divided by 872 is 7 with a remainder of 376.
The next digit of our result is 7. 
Result so far: 6284.850917
Subtract 6104 from 6480 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

On to step 14:
3760 divided by 872 is 4 with a remainder of 272.
Use 4 as the next digit of our solution. 
Result so far: 6284.8509174
Subtracting 3488 from 3760 leaves us with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Let's proceed to step 15:
872 goes into 2720 3 times with a remainder of 104.
The next digit of our result is 3. 
Result so far: 6284.85091743
Deduct 2616 from 2720 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

In conclusion, the division gives 6284.85091743 with a balance of 1.04e-07.
