Let's divide 686293 by 18
We want to divide 686293 by 18.

Step 1:
18 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 18

Advancing to step 2:
When dividing 68 by 18, we get 3 with a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 14 after subtracting 54 from 68.
Include the next digit (6) from the dividend after 14, then repeat: 146 / 18

Step 3:
18 can be fit into 146 8 times, resulting in a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 38.0
Subtract 144 from 146 to get 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 18

Going ahead to step 4:
22 divided by 18 is 1 with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 381.0
Deduct 18 from 22 and we're left with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 18

Advancing to step 5:
The number 18 fits into 49 2 times, leaving a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 3812.0
Subtracting 36 from 49 leaves us with 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 18

Let's proceed to step 6:
18 goes into 133 7 times with a remainder of 7.
The next digit of our result is 7. 
Result so far: 38127.0
Deduct 126 from 133 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
The number 18 fits into 70 3 times, leaving a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 38127.3
The remainder is 16 after subtracting 54 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
18 goes into 160 8 times with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 38127.38
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
The number 18 fits into 160 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 38127.388
If we take 144 away from 160, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 38127.388, and the remainder is 0.0016.
