86277249 divided by 91 
Our goal is to divide 86277249 by 91.

Step 1:
If we divide 8 by 91, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 91

Step 2:
If we divide 86 by 91, we get 0 and a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Take the next digit (2) from the dividend and append it to 86, then repeat: 862 / 91

Advancing to step 3:
91 goes into 862 9 times with a remainder of 43.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 819 from 862 leaves us with 43.
Take the next digit (7) from the dividend and append it to 43, then repeat: 437 / 91

Going ahead to step 4:
91 can be fit into 437 4 times, resulting in a remainder of 73.
Record the quotient 4 as the next digit in the result. 
Result so far: 94.0
Deduct 364 from 437 and we're left with 73.
Bring next digit (7) of the dividend behind the 73 and repeat the process: 737 / 91

On to step 5:
If we divide 737 by 91, we get 8 and a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 948.0
The remainder is 9 after subtracting 728 from 737.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 91

Going ahead to step 6:
91 goes into 92 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 9481.0
Deduct 91 from 92 and we're left with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 91

Let's proceed to step 7:
91 can be fit into 14 0 times, resulting in a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 94810.0
If we take 0 away from 14, we end up with 14.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 91

On to step 8:
149 divided by 91 is 1 with a remainder of 58.
Write down 1 as next digit of the result. 
Result so far: 948101.0
If we subtract 91 from 149, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 9:
The number 91 fits into 580 6 times, leaving a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 948101.6
Subtract 546 from 580 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 10:
If we divide 340 by 91, we get 3 and a remainder of 67.
The next digit of our result is 3. 
Result so far: 948101.63
If we take 273 away from 340, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 11:
When dividing 670 by 91, we get 7 with a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 948101.637
If we take 637 away from 670, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 12:
When dividing 330 by 91, we get 3 with a remainder of 57.
Write down 3 as next digit of the result. 
Result so far: 948101.6373
If we take 273 away from 330, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 13:
570 divided by 91 is 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 948101.63736
Subtracting 546 from 570 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 14:
The number 91 fits into 240 2 times, leaving a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 948101.637362
The remainder is 58 after subtracting 182 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 15:
580 divided by 91 is 6 with a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 948101.6373626
Deduct 546 from 580 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 16:
When dividing 340 by 91, we get 3 with a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 948101.63736263
The remainder is 67 after subtracting 273 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

In conclusion, the division gives 948101.63736263 with a balance of 6.7e-08.
