We divide 8859 by 91
We want to divide 8859 by 91.

On to step 1:
When dividing 8 by 91, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 91

Moving on to step 2:
91 goes into 88 0 times with a remainder of 88.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 88 and we're left with 88.
Take the next digit (5) from the dividend and append it to 88, then repeat: 885 / 91

Moving on to step 3:
The number 91 fits into 885 9 times, leaving a remainder of 66.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 819 from 885 to get 66.
Bring next digit (9) of the dividend behind the 66 and repeat the process: 669 / 91

Moving on to step 4:
91 can be fit into 669 7 times, resulting in a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 97.0
If we take 637 away from 669, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 5:
When dividing 320 by 91, we get 3 with a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 97.3
Subtract 273 from 320 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 6:
The number 91 fits into 470 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 97.35
Subtract 455 from 470 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
150 divided by 91 is 1 with a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 97.351
Deduct 91 from 150 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 8:
91 can be fit into 590 6 times, resulting in a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 97.3516
If we subtract 546 from 590, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
91 goes into 440 4 times with a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 97.35164
Deduct 364 from 440 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 10:
760 divided by 91 is 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 97.351648
If we subtract 728 from 760, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 11:
91 can be fit into 320 3 times, resulting in a remainder of 47.
The next digit of our result is 3. 
Result so far: 97.3516483
Subtracting 273 from 320 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 12:
91 goes into 470 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 97.35164835
If we take 455 away from 470, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 97.35164835, with a leftover of 1.5e-08.
