We divide 115859 by 9
Let's see how many times 9 fits into 115859.

Going ahead to step 1:
If we divide 1 by 9, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 9

Let's proceed to step 2:
When dividing 11 by 9, we get 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 9 from 11 leaves us with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 9

Going ahead to step 3:
When dividing 25 by 9, we get 2 with a remainder of 7.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 18 from 25 to get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 9

Step 4:
78 divided by 9 is 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 128.0
Deduct 72 from 78 and we're left with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 9

Moving on to step 5:
9 goes into 65 7 times with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 1287.0
If we subtract 63 from 65, we get 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 9

Advancing to step 6:
The number 9 fits into 29 3 times, leaving a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 12873.0
If we take 27 away from 29, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
9 goes into 20 2 times with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 12873.2
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
9 can be fit into 20 2 times, resulting in a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 12873.22
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 12873.22, and the remainder is 0.002.
