Let's divide 865453 by 18
We want to divide 865453 by 18.

Advancing to step 1:
8 divided by 18 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 18

Moving on to step 2:
18 goes into 86 4 times with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 72 from 86, we get 14.
Bring next digit (5) of the dividend behind the 14 and repeat the process: 145 / 18

Advancing to step 3:
If we divide 145 by 18, we get 8 and a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 48.0
Deduct 144 from 145 and we're left with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 18

On to step 4:
18 can be fit into 14 0 times, resulting in a remainder of 14.
The next digit of our result is 0. 
Result so far: 480.0
Deduct 0 from 14 and we're left with 14.
Take the next digit (5) from the dividend and append it to 14, then repeat: 145 / 18

Let's proceed to step 5:
When dividing 145 by 18, we get 8 with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 4808.0
The remainder is 1 after subtracting 144 from 145.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 18

Let's proceed to step 6:
The number 18 fits into 13 0 times, leaving a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 48080.0
If we subtract 0 from 13, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
When dividing 130 by 18, we get 7 with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 48080.7
Subtract 126 from 130 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
40 divided by 18 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 48080.72
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
40 divided by 18 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 48080.722
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 48080.722, and the remainder is 0.0004.
