We look at the division of 14028838 by 881 
The aim is to understand the frequency of 881 in 14028838.

Let's proceed to step 1:
When dividing 1 by 881, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 881

Advancing to step 2:
14 divided by 881 is 0 with a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 881

Step 3:
When dividing 140 by 881, we get 0 with a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 140 to get 140.
Bring next digit (2) of the dividend behind the 140 and repeat the process: 1402 / 881

Moving on to step 4:
When dividing 1402 by 881, we get 1 with a remainder of 521.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 881 from 1402 leaves us with 521.
Bring next digit (8) of the dividend behind the 521 and repeat the process: 5218 / 881

Step 5:
The number 881 fits into 5218 5 times, leaving a remainder of 813.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 4405 from 5218 and we're left with 813.
Bring next digit (8) of the dividend behind the 813 and repeat the process: 8138 / 881

Step 6:
881 can be fit into 8138 9 times, resulting in a remainder of 209.
Write down 9 as next digit of the result. 
Result so far: 159.0
Subtracting 7929 from 8138 leaves us with 209.
Grab the next digit (3) from the dividend, add it to 209, then carry on: 2093 / 881

Advancing to step 7:
2093 divided by 881 is 2 with a remainder of 331.
Record the quotient 2 as the next digit in the result. 
Result so far: 1592.0
Deduct 1762 from 2093 and we're left with 331.
Bring next digit (8) of the dividend behind the 331 and repeat the process: 3318 / 881

Moving on to step 8:
The number 881 fits into 3318 3 times, leaving a remainder of 675.
The next digit of our result is 3. 
Result so far: 15923.0
Deduct 2643 from 3318 and we're left with 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

On to step 9:
6750 divided by 881 is 7 with a remainder of 583.
Put 7 as the next digit of the answer. 
Result so far: 15923.7
The remainder is 583 after subtracting 6167 from 6750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

Advancing to step 10:
881 can be fit into 5830 6 times, resulting in a remainder of 544.
The number 6 becomes the next digit in our result. 
Result so far: 15923.76
Subtracting 5286 from 5830 leaves us with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Going ahead to step 11:
If we divide 5440 by 881, we get 6 and a remainder of 154.
The number 6 becomes the next digit in our result. 
Result so far: 15923.766
Subtracting 5286 from 5440 leaves us with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

After the division, we end up with 15923.766 and a remainder of 0.0154.
