We're dividing 860604 by 86 
Let's see how many times 86 fits into 860604.

On to step 1:
86 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 86

Moving on to step 2:
86 goes into 86 1 times with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 0 after subtracting 86 from 86.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 86

Let's proceed to step 3:
86 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 0 leaves us with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 86

Going ahead to step 4:
If we divide 6 by 86, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 100.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 86

Let's proceed to step 5:
60 divided by 86 is 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 1000.0
If we take 0 away from 60, we end up with 60.
Bring next digit (4) of the dividend behind the 60 and repeat the process: 604 / 86

Step 6:
If we divide 604 by 86, we get 7 and a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 10007.0
Subtracting 602 from 604 leaves us 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.

Let's proceed to step 7:
86 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 10007.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
200 divided by 86 is 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 10007.02
If we subtract 172 from 200, we get 28.
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 9:
The number 86 fits into 280 3 times, leaving a remainder of 22.
The next digit of our result is 3. 
Result so far: 10007.023
If we subtract 258 from 280, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 10:
If we divide 220 by 86, we get 2 and a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 10007.0232
Deduct 172 from 220 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
When dividing 480 by 86, we get 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 10007.02325
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 12:
The number 86 fits into 500 5 times, leaving a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 10007.023255
Subtracting 430 from 500 leaves us 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.

The final result is 10007.023255 with a remainder of 7e-06.
