We're dividing 77984237 by 881 
The aim is to understand the frequency of 881 in 77984237.

Moving on to step 1:
7 divided by 881 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 881

On to step 2:
881 goes into 77 0 times with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Bring next digit (9) of the dividend behind the 77 and repeat the process: 779 / 881

Advancing to step 3:
When dividing 779 by 881, we get 0 with a remainder of 779.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 779 and we're left with 779.
Fetch the next digit (8) from the dividend, attach it to 779 and continue: 7798 / 881

Let's proceed to step 4:
7798 divided by 881 is 8 with a remainder of 750.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 7048 away from 7798, we end up with 750.
Take the next digit (4) from the dividend and append it to 750, then repeat: 7504 / 881

Let's proceed to step 5:
The number 881 fits into 7504 8 times, leaving a remainder of 456.
Write down 8 as next digit of the result. 
Result so far: 88.0
If we subtract 7048 from 7504, we get 456.
Fetch the next digit (2) from the dividend, attach it to 456 and continue: 4562 / 881

Let's proceed to step 6:
If we divide 4562 by 881, we get 5 and a remainder of 157.
Put 5 as the next digit of the answer. 
Result so far: 885.0
If we subtract 4405 from 4562, we get 157.
Fetch the next digit (3) from the dividend, attach it to 157 and continue: 1573 / 881

On to step 7:
If we divide 1573 by 881, we get 1 and a remainder of 692.
Write down 1 as next digit of the result. 
Result so far: 8851.0
Subtract 881 from 1573 to get 692.
Bring next digit (7) of the dividend behind the 692 and repeat the process: 6927 / 881

Advancing to step 8:
881 can be fit into 6927 7 times, resulting in a remainder of 760.
The next digit of our result is 7. 
Result so far: 88517.0
The remainder is 760 after subtracting 6167 from 6927.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Advancing to step 9:
881 goes into 7600 8 times with a remainder of 552.
Record the quotient 8 as the next digit in the result. 
Result so far: 88517.8
Deduct 7048 from 7600 and we're left with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Advancing to step 10:
If we divide 5520 by 881, we get 6 and a remainder of 234.
Use 6 as the next digit of our solution. 
Result so far: 88517.86
Subtracting 5286 from 5520 leaves us with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Moving on to step 11:
The number 881 fits into 2340 2 times, leaving a remainder of 578.
The number 2 becomes the next digit in our result. 
Result so far: 88517.862
Deduct 1762 from 2340 and we're left with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Moving on to step 12:
881 can be fit into 5780 6 times, resulting in a remainder of 494.
Write down 6 as next digit of the result. 
Result so far: 88517.8626
Subtract 5286 from 5780 to get 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

On to step 13:
881 can be fit into 4940 5 times, resulting in a remainder of 535.
Put 5 as the next digit of the answer. 
Result so far: 88517.86265
Deduct 4405 from 4940 and we're left with 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Step 14:
If we divide 5350 by 881, we get 6 and a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 88517.862656
If we subtract 5286 from 5350, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 15:
640 divided by 881 is 0 with a remainder of 640.
Record the quotient 0 as the next digit in the result. 
Result so far: 88517.862656
Subtract 0 from 640 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 16:
When dividing 6400 by 881, we get 7 with a remainder of 233.
Use 7 as the next digit of our solution. 
Result so far: 88517.86265607
If we take 6167 away from 6400, we end up with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

The final outcome is 88517.86265607, with a leftover of 2.33e-07.
