69122916 ÷ 81 
We want to figure out the number of times 69122916 can be divided by 81.

Going ahead to step 1:
6 divided by 81 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 81

Advancing to step 2:
When dividing 69 by 81, we get 0 with a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 69, we get 69.
Bring next digit (1) of the dividend behind the 69 and repeat the process: 691 / 81

Going ahead to step 3:
81 can be fit into 691 8 times, resulting in a remainder of 43.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 648 from 691, we get 43.
Take the next digit (2) from the dividend and append it to 43, then repeat: 432 / 81

On to step 4:
If we divide 432 by 81, we get 5 and a remainder of 27.
Write down 5 as next digit of the result. 
Result so far: 85.0
Deduct 405 from 432 and we're left with 27.
Bring next digit (2) of the dividend behind the 27 and repeat the process: 272 / 81

Going ahead to step 5:
The number 81 fits into 272 3 times, leaving a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 853.0
If we take 243 away from 272, we end up with 29.
Bring next digit (9) of the dividend behind the 29 and repeat the process: 299 / 81

Let's proceed to step 6:
When dividing 299 by 81, we get 3 with a remainder of 56.
Put 3 as the next digit of the answer. 
Result so far: 8533.0
If we subtract 243 from 299, we get 56.
Bring next digit (1) of the dividend behind the 56 and repeat the process: 561 / 81

Moving on to step 7:
81 can be fit into 561 6 times, resulting in a remainder of 75.
Write down 6 as next digit of the result. 
Result so far: 85336.0
Subtract 486 from 561 to get 75.
Include the next digit (6) from the dividend after 75, then repeat: 756 / 81

Moving on to step 8:
81 can be fit into 756 9 times, resulting in a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 853369.0
If we take 729 away from 756, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 9:
When dividing 270 by 81, we get 3 with a remainder of 27.
The next digit of our result is 3. 
Result so far: 853369.3
Subtracting 243 from 270 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 10:
The number 81 fits into 270 3 times, leaving a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 853369.33
Deduct 243 from 270 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final result is 853369.33 with a remainder of 0.027.
