370393 ÷ 18 
Let's see how many times 18 fits into 370393.

Advancing to step 1:
When dividing 3 by 18, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 18

Let's proceed to step 2:
37 divided by 18 is 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 36 from 37, we get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 18

Step 3:
The number 18 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Deduct 0 from 10 and we're left with 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 18

Going ahead to step 4:
If we divide 103 by 18, we get 5 and a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 205.0
Subtracting 90 from 103 leaves us with 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 18

Moving on to step 5:
If we divide 139 by 18, we get 7 and a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 2057.0
If we take 126 away from 139, we end up with 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 18

On to step 6:
18 can be fit into 133 7 times, resulting in a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 20577.0
Subtract 126 from 133 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
The number 18 fits into 70 3 times, leaving a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 20577.3
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.

On to step 8:
If we divide 160 by 18, we get 8 and a remainder of 16.
The next digit of our result is 8. 
Result so far: 20577.38
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.

Going ahead to step 9:
When dividing 160 by 18, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 20577.388
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.

The final result is 20577.388 with a remainder of 0.0016.
