Let's divide 16227853 by 872
The aim is to understand the frequency of 872 in 16227853.

Step 1:
If we divide 1 by 872, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 872

Going ahead to step 2:
872 goes into 16 0 times with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Fetch the next digit (2) from the dividend, attach it to 16 and continue: 162 / 872

Advancing to step 3:
872 goes into 162 0 times with a remainder of 162.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 162 and we're left with 162.
Append the next digit (2) from the dividend to 162 and continue with: 1622 / 872

Step 4:
If we divide 1622 by 872, we get 1 and a remainder of 750.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 872 away from 1622, we end up with 750.
Append the next digit (7) from the dividend to 750 and continue with: 7507 / 872

Step 5:
If we divide 7507 by 872, we get 8 and a remainder of 531.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Deduct 6976 from 7507 and we're left with 531.
Append the next digit (8) from the dividend to 531 and continue with: 5318 / 872

Step 6:
When dividing 5318 by 872, we get 6 with a remainder of 86.
Use 6 as the next digit of our solution. 
Result so far: 186.0
If we subtract 5232 from 5318, we get 86.
Include the next digit (5) from the dividend after 86, then repeat: 865 / 872

Going ahead to step 7:
865 divided by 872 is 0 with a remainder of 865.
The next digit of our result is 0. 
Result so far: 1860.0
The remainder is 865 after subtracting 0 from 865.
Include the next digit (3) from the dividend after 865, then repeat: 8653 / 872

Moving on to step 8:
When dividing 8653 by 872, we get 9 with a remainder of 805.
The number 9 becomes the next digit in our result. 
Result so far: 18609.0
If we take 7848 away from 8653, we end up with 805.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8050, and continue the process.

On to step 9:
872 can be fit into 8050 9 times, resulting in a remainder of 202.
Record the quotient 9 as the next digit in the result. 
Result so far: 18609.9
Subtracting 7848 from 8050 leaves us with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Advancing to step 10:
The number 872 fits into 2020 2 times, leaving a remainder of 276.
The number 2 becomes the next digit in our result. 
Result so far: 18609.92
Subtract 1744 from 2020 to get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

On to step 11:
If we divide 2760 by 872, we get 3 and a remainder of 144.
Write down 3 as next digit of the result. 
Result so far: 18609.923
If we take 2616 away from 2760, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 12:
1440 divided by 872 is 1 with a remainder of 568.
The next digit of our result is 1. 
Result so far: 18609.9231
If we take 872 away from 1440, we end up with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Step 13:
The number 872 fits into 5680 6 times, leaving a remainder of 448.
Write down 6 as next digit of the result. 
Result so far: 18609.92316
If we subtract 5232 from 5680, we get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Step 14:
If we divide 4480 by 872, we get 5 and a remainder of 120.
Write down 5 as next digit of the result. 
Result so far: 18609.923165
If we take 4360 away from 4480, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 15:
When dividing 1200 by 872, we get 1 with a remainder of 328.
The number 1 becomes the next digit in our result. 
Result so far: 18609.9231651
Subtracting 872 from 1200 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Going ahead to step 16:
872 can be fit into 3280 3 times, resulting in a remainder of 664.
Use 3 as the next digit of our solution. 
Result so far: 18609.92316513
Subtract 2616 from 3280 to get 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

The final outcome is 18609.92316513, with a leftover of 6.64e-07.
