82886761 ÷ 837 
The aim is to understand the frequency of 837 in 82886761.

Let's proceed to step 1:
If we divide 8 by 837, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 837

Advancing to step 2:
When dividing 82 by 837, we get 0 with a remainder of 82.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 82 leaves us with 82.
Append the next digit (8) from the dividend to 82 and continue with: 828 / 837

Going ahead to step 3:
837 can be fit into 828 0 times, resulting in a remainder of 828.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 828, we get 828.
Take the next digit (8) from the dividend and append it to 828, then repeat: 8288 / 837

Step 4:
8288 divided by 837 is 9 with a remainder of 755.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 7533 from 8288 to get 755.
Fetch the next digit (6) from the dividend, attach it to 755 and continue: 7556 / 837

Step 5:
When dividing 7556 by 837, we get 9 with a remainder of 23.
The next digit of our result is 9. 
Result so far: 99.0
Subtracting 7533 from 7556 leaves us with 23.
Grab the next digit (7) from the dividend, add it to 23, then carry on: 237 / 837

On to step 6:
When dividing 237 by 837, we get 0 with a remainder of 237.
The number 0 becomes the next digit in our result. 
Result so far: 990.0
If we subtract 0 from 237, we get 237.
Bring next digit (6) of the dividend behind the 237 and repeat the process: 2376 / 837

Moving on to step 7:
2376 divided by 837 is 2 with a remainder of 702.
The number 2 becomes the next digit in our result. 
Result so far: 9902.0
Subtract 1674 from 2376 to get 702.
Append the next digit (1) from the dividend to 702 and continue with: 7021 / 837

Advancing to step 8:
If we divide 7021 by 837, we get 8 and a remainder of 325.
Write down 8 as next digit of the result. 
Result so far: 99028.0
Subtracting 6696 from 7021 leaves us with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Moving on to step 9:
837 goes into 3250 3 times with a remainder of 739.
The next digit of our result is 3. 
Result so far: 99028.3
If we take 2511 away from 3250, we end up with 739.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7390, and continue the process.

On to step 10:
7390 divided by 837 is 8 with a remainder of 694.
Put 8 as the next digit of the answer. 
Result so far: 99028.38
If we take 6696 away from 7390, we end up with 694.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6940, and continue the process.

Going ahead to step 11:
When dividing 6940 by 837, we get 8 with a remainder of 244.
Put 8 as the next digit of the answer. 
Result so far: 99028.388
If we take 6696 away from 6940, we end up with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

The final result is 99028.388 with a remainder of 0.0244.
