Let's divide 6486714 by 18
Let's see how many times 18 fits into 6486714.

On to step 1:
18 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 18

Advancing to step 2:
The number 18 fits into 64 3 times, leaving a remainder of 10.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 54 from 64 leaves us with 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 18

Going ahead to step 3:
If we divide 108 by 18, we get 6 and a remainder of 0.
The next digit of our result is 6. 
Result so far: 36.0
If we take 108 away from 108, we end up with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 18

Advancing to step 4:
18 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 360.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 18

Moving on to step 5:
18 can be fit into 67 3 times, resulting in a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 3603.0
Subtract 54 from 67 to get 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 18

Advancing to step 6:
The number 18 fits into 131 7 times, leaving a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 36037.0
Subtracting 126 from 131 leaves us with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 18

Step 7:
If we divide 54 by 18, we get 3 and a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 360373.0
Subtract 54 from 54 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.

On to step 8:
18 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 360373.0
Deduct 0 from 0 and we're left 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.

Let's proceed to step 9:
If we divide 0 by 18, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 360373.0
The remainder is 0 after subtracting 0 from 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 outcome is 360373.0, with a leftover of 0.0.
