We're dividing 863723 by 91 
We're looking to find how many times 91 goes into 863723.

On to step 1:
91 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 91

On to step 2:
If we divide 86 by 91, we get 0 and a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Fetch the next digit (3) from the dividend, attach it to 86 and continue: 863 / 91

Moving on to step 3:
If we divide 863 by 91, we get 9 and a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 819 from 863 to get 44.
Fetch the next digit (7) from the dividend, attach it to 44 and continue: 447 / 91

Moving on to step 4:
The number 91 fits into 447 4 times, leaving a remainder of 83.
Write down 4 as next digit of the result. 
Result so far: 94.0
The remainder is 83 after subtracting 364 from 447.
Bring next digit (2) of the dividend behind the 83 and repeat the process: 832 / 91

Going ahead to step 5:
91 can be fit into 832 9 times, resulting in a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 949.0
If we subtract 819 from 832, we get 13.
Fetch the next digit (3) from the dividend, attach it to 13 and continue: 133 / 91

Let's proceed to step 6:
The number 91 fits into 133 1 times, leaving a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 9491.0
Subtract 91 from 133 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 7:
420 divided by 91 is 4 with a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 9491.4
The remainder is 56 after subtracting 364 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 8:
91 goes into 560 6 times with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 9491.46
Subtracting 546 from 560 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
When dividing 140 by 91, we get 1 with a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 9491.461
Subtracting 91 from 140 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 10:
490 divided by 91 is 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 9491.4615
Subtract 455 from 490 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 11:
91 can be fit into 350 3 times, resulting in a remainder of 77.
Put 3 as the next digit of the answer. 
Result so far: 9491.46153
If we subtract 273 from 350, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 12:
When dividing 770 by 91, we get 8 with a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 9491.461538
If we take 728 away from 770, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 13:
If we divide 420 by 91, we get 4 and a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 9491.4615384
If we subtract 364 from 420, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 14:
560 divided by 91 is 6 with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 9491.46153846
Subtract 546 from 560 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 9491.46153846, with a leftover of 1.4e-08.
