385673 ÷ 18 
We want to figure out the number of times 385673 can be divided by 18.

On to step 1:
If we divide 3 by 18, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 18

On to step 2:
18 can be fit into 38 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 36 from 38 to get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 18

On to step 3:
When dividing 25 by 18, we get 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we subtract 18 from 25, we get 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 18

On to step 4:
If we divide 76 by 18, we get 4 and a remainder of 4.
The next digit of our result is 4. 
Result so far: 214.0
Deduct 72 from 76 and we're left with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 18

Moving on to step 5:
If we divide 47 by 18, we get 2 and a remainder of 11.
The next digit of our result is 2. 
Result so far: 2142.0
The remainder is 11 after subtracting 36 from 47.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 18

Going ahead to step 6:
The number 18 fits into 113 6 times, leaving a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 21426.0
The remainder is 5 after subtracting 108 from 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
18 can be fit into 50 2 times, resulting in a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 21426.2
If we take 36 away from 50, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
If we divide 140 by 18, we get 7 and a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 21426.27
If we take 126 away from 140, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 9:
18 can be fit into 140 7 times, resulting in a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 21426.277
The remainder is 14 after subtracting 126 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 21426.277 with a remainder of 0.0014.
