86266797 ÷ 311 
Our goal is to divide 86266797 by 311.

Let's proceed to step 1:
311 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 311

Going ahead to step 2:
86 divided by 311 is 0 with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Take the next digit (2) from the dividend and append it to 86, then repeat: 862 / 311

Moving on to step 3:
862 divided by 311 is 2 with a remainder of 240.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 622 from 862, we get 240.
Grab the next digit (6) from the dividend, add it to 240, then carry on: 2406 / 311

Advancing to step 4:
If we divide 2406 by 311, we get 7 and a remainder of 229.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Deduct 2177 from 2406 and we're left with 229.
Bring next digit (6) of the dividend behind the 229 and repeat the process: 2296 / 311

Advancing to step 5:
311 goes into 2296 7 times with a remainder of 119.
The next digit of our result is 7. 
Result so far: 277.0
Deduct 2177 from 2296 and we're left with 119.
Take the next digit (7) from the dividend and append it to 119, then repeat: 1197 / 311

Step 6:
When dividing 1197 by 311, we get 3 with a remainder of 264.
The number 3 becomes the next digit in our result. 
Result so far: 2773.0
Subtracting 933 from 1197 leaves us with 264.
Append the next digit (9) from the dividend to 264 and continue with: 2649 / 311

Going ahead to step 7:
If we divide 2649 by 311, we get 8 and a remainder of 161.
The number 8 becomes the next digit in our result. 
Result so far: 27738.0
If we subtract 2488 from 2649, we get 161.
Bring next digit (7) of the dividend behind the 161 and repeat the process: 1617 / 311

Let's proceed to step 8:
1617 divided by 311 is 5 with a remainder of 62.
Put 5 as the next digit of the answer. 
Result so far: 277385.0
Subtract 1555 from 1617 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 9:
311 goes into 620 1 times with a remainder of 309.
Use 1 as the next digit of our solution. 
Result so far: 277385.1
Subtracting 311 from 620 leaves us with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

On to step 10:
311 can be fit into 3090 9 times, resulting in a remainder of 291.
Write down 9 as next digit of the result. 
Result so far: 277385.19
If we take 2799 away from 3090, we end up with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Advancing to step 11:
2910 divided by 311 is 9 with a remainder of 111.
Record the quotient 9 as the next digit in the result. 
Result so far: 277385.199
Deduct 2799 from 2910 and we're left with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

In conclusion, the division gives 277385.199 with a balance of 0.0111.
