We're dividing 81724688 by 886 
The aim is to understand the frequency of 886 in 81724688.

Advancing to step 1:
When dividing 8 by 886, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 886

Advancing to step 2:
886 can be fit into 81 0 times, resulting in a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Append the next digit (7) from the dividend to 81 and continue with: 817 / 886

Advancing to step 3:
817 divided by 886 is 0 with a remainder of 817.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 817 leaves us with 817.
Append the next digit (2) from the dividend to 817 and continue with: 8172 / 886

Let's proceed to step 4:
The number 886 fits into 8172 9 times, leaving a remainder of 198.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 7974 from 8172, we get 198.
Grab the next digit (4) from the dividend, add it to 198, then carry on: 1984 / 886

Advancing to step 5:
1984 divided by 886 is 2 with a remainder of 212.
Write down 2 as next digit of the result. 
Result so far: 92.0
Subtracting 1772 from 1984 leaves us with 212.
Bring next digit (6) of the dividend behind the 212 and repeat the process: 2126 / 886

Moving on to step 6:
If we divide 2126 by 886, we get 2 and a remainder of 354.
The number 2 becomes the next digit in our result. 
Result so far: 922.0
Subtracting 1772 from 2126 leaves us with 354.
Grab the next digit (8) from the dividend, add it to 354, then carry on: 3548 / 886

Moving on to step 7:
The number 886 fits into 3548 4 times, leaving a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 9224.0
Subtract 3544 from 3548 to get 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 886

Step 8:
The number 886 fits into 48 0 times, leaving a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 92240.0
If we subtract 0 from 48, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
When dividing 480 by 886, we get 0 with a remainder of 480.
The next digit of our result is 0. 
Result so far: 92240.0
Subtracting 0 from 480 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 10:
886 can be fit into 4800 5 times, resulting in a remainder of 370.
The number 5 becomes the next digit in our result. 
Result so far: 92240.05
If we subtract 4430 from 4800, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Going ahead to step 11:
The number 886 fits into 3700 4 times, leaving a remainder of 156.
Write down 4 as next digit of the result. 
Result so far: 92240.054
Deduct 3544 from 3700 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 12:
886 goes into 1560 1 times with a remainder of 674.
Use 1 as the next digit of our solution. 
Result so far: 92240.0541
The remainder is 674 after subtracting 886 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6740, and continue the process.

Moving on to step 13:
The number 886 fits into 6740 7 times, leaving a remainder of 538.
The number 7 becomes the next digit in our result. 
Result so far: 92240.05417
Subtracting 6202 from 6740 leaves us with 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Moving on to step 14:
The number 886 fits into 5380 6 times, leaving a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 92240.054176
Subtract 5316 from 5380 to 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.

Let's proceed to step 15:
886 can be fit into 640 0 times, resulting in a remainder of 640.
Write down 0 as next digit of the result. 
Result so far: 92240.054176
The remainder is 640 after subtracting 0 from 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:
If we divide 6400 by 886, we get 7 and a remainder of 198.
Put 7 as the next digit of the answer. 
Result so far: 92240.05417607
If we subtract 6202 from 6400, we get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

The final result is 92240.05417607 with a remainder of 1.98e-07.
