We divide 866185 by 75
We want to divide 866185 by 75.

Advancing to step 1:
When dividing 8 by 75, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 75

Let's proceed to step 2:
75 can be fit into 86 1 times, resulting in a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 75 from 86, we get 11.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 75

On to step 3:
116 divided by 75 is 1 with a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 75 from 116 and we're left with 41.
Grab the next digit (1) from the dividend, add it to 41, then carry on: 411 / 75

Moving on to step 4:
75 goes into 411 5 times with a remainder of 36.
Write down 5 as next digit of the result. 
Result so far: 115.0
Subtract 375 from 411 to get 36.
Include the next digit (8) from the dividend after 36, then repeat: 368 / 75

Going ahead to step 5:
75 goes into 368 4 times with a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 1154.0
Deduct 300 from 368 and we're left with 68.
Append the next digit (5) from the dividend to 68 and continue with: 685 / 75

Going ahead to step 6:
685 divided by 75 is 9 with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 11549.0
Subtract 675 from 685 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
100 divided by 75 is 1 with a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 11549.1
The remainder is 25 after subtracting 75 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 8:
75 goes into 250 3 times with a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 11549.13
Subtract 225 from 250 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
The number 75 fits into 250 3 times, leaving a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 11549.133
Subtracting 225 from 250 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 11549.133 and a remainder of 0.0025.
