Let's divide 864409 by 91
Let's see how many times 91 fits into 864409.

Let's proceed to step 1:
8 divided by 91 is 0 with 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

Going ahead to step 2:
When dividing 86 by 91, we get 0 with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Bring next digit (4) of the dividend behind the 86 and repeat the process: 864 / 91

On to step 3:
If we divide 864 by 91, we get 9 and a remainder of 45.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 45 after subtracting 819 from 864.
Grab the next digit (4) from the dividend, add it to 45, then carry on: 454 / 91

Advancing to step 4:
454 divided by 91 is 4 with a remainder of 90.
Write down 4 as next digit of the result. 
Result so far: 94.0
Subtract 364 from 454 to get 90.
Bring next digit (0) of the dividend behind the 90 and repeat the process: 900 / 91

Step 5:
The number 91 fits into 900 9 times, leaving a remainder of 81.
Use 9 as the next digit of our solution. 
Result so far: 949.0
The remainder is 81 after subtracting 819 from 900.
Bring next digit (9) of the dividend behind the 81 and repeat the process: 819 / 91

Step 6:
91 goes into 819 9 times with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 9499.0
Deduct 819 from 819 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
If we divide 0 by 91, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9499.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
The number 91 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9499.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 9499.0, and the remainder is 0.0.
