1686466 divided by 18 
Let's see how many times 18 fits into 1686466.

Going ahead to step 1:
18 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 18

Step 2:
The number 18 fits into 16 0 times, leaving a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Include the next digit (8) from the dividend after 16, then repeat: 168 / 18

Advancing to step 3:
18 can be fit into 168 9 times, resulting in a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 162 from 168 leaves us with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 18

Let's proceed to step 4:
When dividing 66 by 18, we get 3 with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 93.0
Deduct 54 from 66 and we're left with 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 18

Moving on to step 5:
18 goes into 124 6 times with a remainder of 16.
The next digit of our result is 6. 
Result so far: 936.0
The remainder is 16 after subtracting 108 from 124.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 18

Let's proceed to step 6:
18 can be fit into 166 9 times, resulting in a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 9369.0
Deduct 162 from 166 and we're left with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 18

Step 7:
If we divide 46 by 18, we get 2 and a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 93692.0
Subtracting 36 from 46 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.

Advancing to step 8:
18 can be fit into 100 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 93692.5
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.

On to step 9:
18 goes into 100 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 93692.55
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.

The quotient of the division is 93692.55, and the remainder is 0.01.
