Let's divide 86724486 by 18
Our goal is to divide 86724486 by 18.

Let's proceed to step 1:
18 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 18

Going ahead to step 2:
86 divided by 18 is 4 with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 14 after subtracting 72 from 86.
Append the next digit (7) from the dividend to 14 and continue with: 147 / 18

Going ahead to step 3:
18 goes into 147 8 times with a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
Deduct 144 from 147 and we're left with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 18

Going ahead to step 4:
If we divide 32 by 18, we get 1 and a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 481.0
If we take 18 away from 32, we end up with 14.
Take the next digit (4) from the dividend and append it to 14, then repeat: 144 / 18

Let's proceed to step 5:
When dividing 144 by 18, we get 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 4818.0
The remainder is 0 after subtracting 144 from 144.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 18

Moving on to step 6:
The number 18 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 48180.0
If we subtract 0 from 4, we get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 18

Let's proceed to step 7:
When dividing 48 by 18, we get 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 481802.0
Subtracting 36 from 48 leaves us with 12.
Append the next digit (6) from the dividend to 12 and continue with: 126 / 18

Going ahead to step 8:
126 divided by 18 is 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 4818027.0
If we subtract 126 from 126, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
If we divide 0 by 18, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4818027.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
The number 18 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4818027.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 4818027.0 with a remainder of 0.0.
