We're dividing 16087923 by 881 
The aim is to understand the frequency of 881 in 16087923.

Advancing to step 1:
If we divide 1 by 881, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 881

Going ahead to step 2:
If we divide 16 by 881, we get 0 and a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Take the next digit (0) from the dividend and append it to 16, then repeat: 160 / 881

Moving on to step 3:
The number 881 fits into 160 0 times, leaving a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 160 leaves us with 160.
Include the next digit (8) from the dividend after 160, then repeat: 1608 / 881

On to step 4:
When dividing 1608 by 881, we get 1 with a remainder of 727.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 881 from 1608, we get 727.
Bring next digit (7) of the dividend behind the 727 and repeat the process: 7277 / 881

Moving on to step 5:
When dividing 7277 by 881, we get 8 with a remainder of 229.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we take 7048 away from 7277, we end up with 229.
Include the next digit (9) from the dividend after 229, then repeat: 2299 / 881

Let's proceed to step 6:
881 goes into 2299 2 times with a remainder of 537.
Put 2 as the next digit of the answer. 
Result so far: 182.0
Deduct 1762 from 2299 and we're left with 537.
Grab the next digit (2) from the dividend, add it to 537, then carry on: 5372 / 881

Advancing to step 7:
If we divide 5372 by 881, we get 6 and a remainder of 86.
Use 6 as the next digit of our solution. 
Result so far: 1826.0
Deduct 5286 from 5372 and we're left with 86.
Include the next digit (3) from the dividend after 86, then repeat: 863 / 881

Step 8:
881 goes into 863 0 times with a remainder of 863.
Use 0 as the next digit of our solution. 
Result so far: 18260.0
Subtracting 0 from 863 leaves us with 863.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8630, and continue the process.

Let's proceed to step 9:
The number 881 fits into 8630 9 times, leaving a remainder of 701.
Put 9 as the next digit of the answer. 
Result so far: 18260.9
Subtract 7929 from 8630 to get 701.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7010, and continue the process.

Step 10:
881 can be fit into 7010 7 times, resulting in a remainder of 843.
The number 7 becomes the next digit in our result. 
Result so far: 18260.97
Subtract 6167 from 7010 to get 843.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8430, and continue the process.

Advancing to step 11:
When dividing 8430 by 881, we get 9 with a remainder of 501.
The next digit of our result is 9. 
Result so far: 18260.979
The remainder is 501 after subtracting 7929 from 8430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Let's proceed to step 12:
881 goes into 5010 5 times with a remainder of 605.
Use 5 as the next digit of our solution. 
Result so far: 18260.9795
If we take 4405 away from 5010, we end up with 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

Going ahead to step 13:
The number 881 fits into 6050 6 times, leaving a remainder of 764.
Write down 6 as next digit of the result. 
Result so far: 18260.97956
If we take 5286 away from 6050, we end up with 764.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

Step 14:
881 goes into 7640 8 times with a remainder of 592.
Use 8 as the next digit of our solution. 
Result so far: 18260.979568
If we take 7048 away from 7640, we end up with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Moving on to step 15:
881 goes into 5920 6 times with a remainder of 634.
The next digit of our result is 6. 
Result so far: 18260.9795686
Deduct 5286 from 5920 and we're left with 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

Moving on to step 16:
881 goes into 6340 7 times with a remainder of 173.
The number 7 becomes the next digit in our result. 
Result so far: 18260.97956867
If we take 6167 away from 6340, we end up with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

The final outcome is 18260.97956867, with a leftover of 1.73e-07.
