Let's divide 357499 by 18
We want to figure out the number of times 357499 can be divided by 18.

Step 1:
18 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 18

Advancing to step 2:
The number 18 fits into 35 1 times, leaving 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.
Include the next digit (7) from the dividend after 17, then repeat: 177 / 18

Going ahead to step 3:
The number 18 fits into 177 9 times, leaving a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Deduct 162 from 177 and we're left with 15.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 18

Let's proceed to step 4:
154 divided by 18 is 8 with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 198.0
The remainder is 10 after subtracting 144 from 154.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 18

Step 5:
The number 18 fits into 109 6 times, leaving a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 1986.0
If we subtract 108 from 109, we get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 18

Advancing to step 6:
18 goes into 19 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 19861.0
Deduct 18 from 19 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
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: 19861.0
If we subtract 0 from 10, 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.

Going ahead to step 8:
When dividing 100 by 18, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 19861.05
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.

Let's proceed to step 9:
18 goes into 100 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 19861.055
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.

The final result is 19861.055 with a remainder of 0.001.
