We're dividing 68992839 by 864 
We want to figure out the number of times 68992839 can be divided by 864.

Step 1:
864 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 864

Step 2:
When dividing 68 by 864, we get 0 with a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Grab the next digit (9) from the dividend, add it to 68, then carry on: 689 / 864

Step 3:
When dividing 689 by 864, we get 0 with a remainder of 689.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 689, we get 689.
Take the next digit (9) from the dividend and append it to 689, then repeat: 6899 / 864

Moving on to step 4:
The number 864 fits into 6899 7 times, leaving a remainder of 851.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 6048 from 6899 leaves us with 851.
Append the next digit (2) from the dividend to 851 and continue with: 8512 / 864

Step 5:
864 goes into 8512 9 times with a remainder of 736.
Use 9 as the next digit of our solution. 
Result so far: 79.0
Deduct 7776 from 8512 and we're left with 736.
Include the next digit (8) from the dividend after 736, then repeat: 7368 / 864

Going ahead to step 6:
When dividing 7368 by 864, we get 8 with a remainder of 456.
The next digit of our result is 8. 
Result so far: 798.0
If we take 6912 away from 7368, we end up with 456.
Bring next digit (3) of the dividend behind the 456 and repeat the process: 4563 / 864

Let's proceed to step 7:
864 can be fit into 4563 5 times, resulting in a remainder of 243.
The next digit of our result is 5. 
Result so far: 7985.0
Deduct 4320 from 4563 and we're left with 243.
Include the next digit (9) from the dividend after 243, then repeat: 2439 / 864

On to step 8:
864 goes into 2439 2 times with a remainder of 711.
Record the quotient 2 as the next digit in the result. 
Result so far: 79852.0
Subtracting 1728 from 2439 leaves us with 711.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7110, and continue the process.

On to step 9:
864 goes into 7110 8 times with a remainder of 198.
The number 8 becomes the next digit in our result. 
Result so far: 79852.8
If we take 6912 away from 7110, we end up with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Step 10:
When dividing 1980 by 864, we get 2 with a remainder of 252.
The number 2 becomes the next digit in our result. 
Result so far: 79852.82
If we take 1728 away from 1980, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 11:
864 can be fit into 2520 2 times, resulting in a remainder of 792.
Record the quotient 2 as the next digit in the result. 
Result so far: 79852.822
Subtracting 1728 from 2520 leaves us with 792.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7920, and continue the process.

The quotient of the division is 79852.822, and the remainder is 0.0792.
