We look at the division of 18189210 by 865 
We're looking to find how many times 865 goes into 18189210.

Let's proceed to step 1:
When dividing 1 by 865, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 865

Let's proceed to step 2:
If we divide 18 by 865, we get 0 and a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 865

On to step 3:
When dividing 181 by 865, we get 0 with a remainder of 181.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 181, we end up with 181.
Bring next digit (8) of the dividend behind the 181 and repeat the process: 1818 / 865

Let's proceed to step 4:
The number 865 fits into 1818 2 times, leaving a remainder of 88.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 88 after subtracting 1730 from 1818.
Append the next digit (9) from the dividend to 88 and continue with: 889 / 865

On to step 5:
The number 865 fits into 889 1 times, leaving a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we take 865 away from 889, we end up with 24.
Append the next digit (2) from the dividend to 24 and continue with: 242 / 865

On to step 6:
If we divide 242 by 865, we get 0 and a remainder of 242.
The number 0 becomes the next digit in our result. 
Result so far: 210.0
Subtracting 0 from 242 leaves us with 242.
Grab the next digit (1) from the dividend, add it to 242, then carry on: 2421 / 865

Let's proceed to step 7:
The number 865 fits into 2421 2 times, leaving a remainder of 691.
Record the quotient 2 as the next digit in the result. 
Result so far: 2102.0
If we take 1730 away from 2421, we end up with 691.
Bring next digit (0) of the dividend behind the 691 and repeat the process: 6910 / 865

Moving on to step 8:
6910 divided by 865 is 7 with a remainder of 855.
Put 7 as the next digit of the answer. 
Result so far: 21027.0
The remainder is 855 after subtracting 6055 from 6910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8550, and continue the process.

Moving on to step 9:
The number 865 fits into 8550 9 times, leaving a remainder of 765.
Record the quotient 9 as the next digit in the result. 
Result so far: 21027.9
The remainder is 765 after subtracting 7785 from 8550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7650, and continue the process.

Moving on to step 10:
865 can be fit into 7650 8 times, resulting in a remainder of 730.
The next digit of our result is 8. 
Result so far: 21027.98
Subtract 6920 from 7650 to get 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Going ahead to step 11:
7300 divided by 865 is 8 with a remainder of 380.
Write down 8 as next digit of the result. 
Result so far: 21027.988
If we subtract 6920 from 7300, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

The quotient of the division is 21027.988, and the remainder is 0.038.
