We're dividing 81805110 by 882 
The aim is to understand the frequency of 882 in 81805110.

Advancing to step 1:
If we divide 8 by 882, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 882

Advancing to step 2:
882 goes into 81 0 times with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Grab the next digit (8) from the dividend, add it to 81, then carry on: 818 / 882

Step 3:
When dividing 818 by 882, we get 0 with a remainder of 818.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 818 leaves us with 818.
Append the next digit (0) from the dividend to 818 and continue with: 8180 / 882

Step 4:
882 goes into 8180 9 times with a remainder of 242.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 7938 from 8180 and we're left with 242.
Take the next digit (5) from the dividend and append it to 242, then repeat: 2425 / 882

Step 5:
If we divide 2425 by 882, we get 2 and a remainder of 661.
The next digit of our result is 2. 
Result so far: 92.0
Deduct 1764 from 2425 and we're left with 661.
Bring next digit (1) of the dividend behind the 661 and repeat the process: 6611 / 882

Advancing to step 6:
The number 882 fits into 6611 7 times, leaving a remainder of 437.
The number 7 becomes the next digit in our result. 
Result so far: 927.0
Deduct 6174 from 6611 and we're left with 437.
Take the next digit (1) from the dividend and append it to 437, then repeat: 4371 / 882

On to step 7:
4371 divided by 882 is 4 with a remainder of 843.
The next digit of our result is 4. 
Result so far: 9274.0
The remainder is 843 after subtracting 3528 from 4371.
Bring next digit (0) of the dividend behind the 843 and repeat the process: 8430 / 882

Moving on to step 8:
8430 divided by 882 is 9 with a remainder of 492.
Write down 9 as next digit of the result. 
Result so far: 92749.0
If we subtract 7938 from 8430, we get 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Moving on to step 9:
The number 882 fits into 4920 5 times, leaving a remainder of 510.
Record the quotient 5 as the next digit in the result. 
Result so far: 92749.5
The remainder is 510 after subtracting 4410 from 4920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Going ahead to step 10:
If we divide 5100 by 882, we get 5 and a remainder of 690.
Use 5 as the next digit of our solution. 
Result so far: 92749.55
Deduct 4410 from 5100 and we're left with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

After the division, we end up with 92749.55 and a remainder of 0.69.
