We divide 385149 by 18
Let's see how many times 18 fits into 385149.

Advancing to step 1:
If we divide 3 by 18, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 18

Step 2:
The number 18 fits into 38 2 times, leaving a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 36 from 38 leaves us with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 18

Let's proceed to step 3:
If we divide 25 by 18, we get 1 and a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we take 18 away from 25, we end up with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 18

Advancing to step 4:
When dividing 71 by 18, we get 3 with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 213.0
The remainder is 17 after subtracting 54 from 71.
Append the next digit (4) from the dividend to 17 and continue with: 174 / 18

Advancing to step 5:
When dividing 174 by 18, we get 9 with a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 2139.0
If we subtract 162 from 174, we get 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 18

On to step 6:
129 divided by 18 is 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 21397.0
If we subtract 126 from 129, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
When dividing 30 by 18, we get 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 21397.1
Subtract 18 from 30 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
18 can be fit into 120 6 times, resulting in a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 21397.16
Subtract 108 from 120 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
18 can be fit into 120 6 times, resulting in a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 21397.166
If we take 108 away from 120, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 21397.166, with a leftover of 0.0012.
