9615 divided by 86 
Let's see how many times 86 fits into 9615.

Step 1:
If we divide 9 by 86, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 86

Step 2:
96 divided by 86 is 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 86 from 96 and we're left with 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 86

On to step 3:
When dividing 101 by 86, we get 1 with a remainder of 15.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 86 from 101 leaves us with 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 86

Advancing to step 4:
86 goes into 155 1 times with a remainder of 69.
The number 1 becomes the next digit in our result. 
Result so far: 111.0
Subtracting 86 from 155 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 5:
86 goes into 690 8 times with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 111.8
If we take 688 away from 690, 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.

Step 6:
When dividing 20 by 86, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 111.8
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 7:
If we divide 200 by 86, we get 2 and a remainder of 28.
The next digit of our result is 2. 
Result so far: 111.802
The remainder is 28 after subtracting 172 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 8:
If we divide 280 by 86, we get 3 and a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 111.8023
Subtracting 258 from 280 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 9:
86 goes into 220 2 times with a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 111.80232
The remainder is 48 after subtracting 172 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 10:
The number 86 fits into 480 5 times, leaving a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 111.802325
If we subtract 430 from 480, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 11:
86 goes into 500 5 times with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 111.8023255
If we take 430 away from 500, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 111.8023255 and a remainder of 7e-07.
