Let's divide 357940 by 18
We want to divide 357940 by 18.

Advancing to step 1:
18 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 18

Advancing to step 2:
When dividing 35 by 18, we get 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 17 after subtracting 18 from 35.
Fetch the next digit (7) from the dividend, attach it to 17 and continue: 177 / 18

On to step 3:
18 can be fit into 177 9 times, resulting in a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we subtract 162 from 177, we get 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 18

Advancing to step 4:
The number 18 fits into 159 8 times, leaving a remainder of 15.
Write down 8 as next digit of the result. 
Result so far: 198.0
The remainder is 15 after subtracting 144 from 159.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 18

Moving on to step 5:
When dividing 154 by 18, we get 8 with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 1988.0
Deduct 144 from 154 and we're left with 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 18

Advancing to step 6:
100 divided by 18 is 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 19885.0
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
100 divided by 18 is 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 19885.5
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.

Let's proceed to step 8:
When dividing 100 by 18, we get 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 19885.55
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 final outcome is 19885.55, with a leftover of 0.01.
