8104 divided by 86 
We want to figure out the number of times 8104 can be divided by 86.

Moving on to step 1:
8 divided by 86 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 86

Moving on to step 2:
86 can be fit into 81 0 times, resulting in a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Grab the next digit (0) from the dividend, add it to 81, then carry on: 810 / 86

Going ahead to step 3:
If we divide 810 by 86, we get 9 and a remainder of 36.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 774 from 810 and we're left with 36.
Grab the next digit (4) from the dividend, add it to 36, then carry on: 364 / 86

Let's proceed to step 4:
86 goes into 364 4 times with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 94.0
Subtracting 344 from 364 leaves us 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.

Going ahead to step 5:
If we divide 200 by 86, we get 2 and a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 94.2
If we take 172 away from 200, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 6:
The number 86 fits into 280 3 times, leaving a remainder of 22.
The next digit of our result is 3. 
Result so far: 94.23
The remainder is 22 after subtracting 258 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
The number 86 fits into 220 2 times, leaving a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 94.232
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.

Advancing to step 8:
86 can be fit into 480 5 times, resulting in a remainder of 50.
The next digit of our result is 5. 
Result so far: 94.2325
If we take 430 away from 480, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
86 can be fit into 500 5 times, resulting in a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 94.23255
If we subtract 430 from 500, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 94.23255 with a remaining 7e-05.
