863470 ÷ 18 
Our goal is to divide 863470 by 18.

On to step 1:
When dividing 8 by 18, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 18

Advancing to step 2:
If we divide 86 by 18, we get 4 and a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 72 from 86, we get 14.
Grab the next digit (3) from the dividend, add it to 14, then carry on: 143 / 18

Advancing to step 3:
The number 18 fits into 143 7 times, leaving a remainder of 17.
The next digit of our result is 7. 
Result so far: 47.0
If we take 126 away from 143, we end up with 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 18

Let's proceed to step 4:
18 goes into 174 9 times with a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 479.0
Subtracting 162 from 174 leaves us with 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 18

Let's proceed to step 5:
127 divided by 18 is 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 4797.0
The remainder is 1 after subtracting 126 from 127.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 18

Advancing to step 6:
18 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 47970.0
If we take 0 away from 10, we end up with 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:
When dividing 100 by 18, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 47970.5
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
18 can be fit into 100 5 times, resulting in a remainder of 10.
The next digit of our result is 5. 
Result so far: 47970.55
If we subtract 90 from 100, we 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.

The quotient of the division is 47970.55, and the remainder is 0.01.
