80309791 ÷ 868 
We want to figure out the number of times 80309791 can be divided by 868.

Moving on to step 1:
868 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 868

Let's proceed to step 2:
868 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Append the next digit (3) from the dividend to 80 and continue with: 803 / 868

Moving on to step 3:
803 divided by 868 is 0 with a remainder of 803.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 803, we end up with 803.
Grab the next digit (0) from the dividend, add it to 803, then carry on: 8030 / 868

On to step 4:
8030 divided by 868 is 9 with a remainder of 218.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 7812 from 8030, we get 218.
Bring next digit (9) of the dividend behind the 218 and repeat the process: 2189 / 868

On to step 5:
If we divide 2189 by 868, we get 2 and a remainder of 453.
Put 2 as the next digit of the answer. 
Result so far: 92.0
Subtract 1736 from 2189 to get 453.
Grab the next digit (7) from the dividend, add it to 453, then carry on: 4537 / 868

Moving on to step 6:
868 can be fit into 4537 5 times, resulting in a remainder of 197.
Write down 5 as next digit of the result. 
Result so far: 925.0
Deduct 4340 from 4537 and we're left with 197.
Grab the next digit (9) from the dividend, add it to 197, then carry on: 1979 / 868

Advancing to step 7:
868 goes into 1979 2 times with a remainder of 243.
The next digit of our result is 2. 
Result so far: 9252.0
If we take 1736 away from 1979, we end up with 243.
Append the next digit (1) from the dividend to 243 and continue with: 2431 / 868

On to step 8:
The number 868 fits into 2431 2 times, leaving a remainder of 695.
The next digit of our result is 2. 
Result so far: 92522.0
Subtract 1736 from 2431 to get 695.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6950, and continue the process.

Advancing to step 9:
868 can be fit into 6950 8 times, resulting in a remainder of 6.
The next digit of our result is 8. 
Result so far: 92522.8
Deduct 6944 from 6950 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 10:
868 can be fit into 60 0 times, resulting in a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 92522.8
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
868 can be fit into 600 0 times, resulting in a remainder of 600.
Put 0 as the next digit of the answer. 
Result so far: 92522.8
Deduct 0 from 600 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

In conclusion, the division gives 92522.8 with a balance of 0.06.
