We're dividing 68927589 by 810 
The aim is to understand the frequency of 810 in 68927589.

Moving on to step 1:
810 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 810

Advancing to step 2:
68 divided by 810 is 0 with a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Take the next digit (9) from the dividend and append it to 68, then repeat: 689 / 810

Moving on to step 3:
810 goes into 689 0 times with a remainder of 689.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 689 and we're left with 689.
Include the next digit (2) from the dividend after 689, then repeat: 6892 / 810

Going ahead to step 4:
810 goes into 6892 8 times with a remainder of 412.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 6480 from 6892 and we're left with 412.
Append the next digit (7) from the dividend to 412 and continue with: 4127 / 810

Step 5:
4127 divided by 810 is 5 with a remainder of 77.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
The remainder is 77 after subtracting 4050 from 4127.
Include the next digit (5) from the dividend after 77, then repeat: 775 / 810

Advancing to step 6:
When dividing 775 by 810, we get 0 with a remainder of 775.
The number 0 becomes the next digit in our result. 
Result so far: 850.0
Subtract 0 from 775 to get 775.
Fetch the next digit (8) from the dividend, attach it to 775 and continue: 7758 / 810

Step 7:
If we divide 7758 by 810, we get 9 and a remainder of 468.
Put 9 as the next digit of the answer. 
Result so far: 8509.0
The remainder is 468 after subtracting 7290 from 7758.
Bring next digit (9) of the dividend behind the 468 and repeat the process: 4689 / 810

Moving on to step 8:
810 goes into 4689 5 times with a remainder of 639.
The next digit of our result is 5. 
Result so far: 85095.0
If we take 4050 away from 4689, we end up with 639.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6390, and continue the process.

Going ahead to step 9:
6390 divided by 810 is 7 with a remainder of 720.
The number 7 becomes the next digit in our result. 
Result so far: 85095.7
Subtract 5670 from 6390 to get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Moving on to step 10:
The number 810 fits into 7200 8 times, leaving a remainder of 720.
Write down 8 as next digit of the result. 
Result so far: 85095.78
Subtract 6480 from 7200 to get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Step 11:
7200 divided by 810 is 8 with a remainder of 720.
The number 8 becomes the next digit in our result. 
Result so far: 85095.788
If we subtract 6480 from 7200, we get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

After the division, we end up with 85095.788 and a remainder of 0.072.
