We look at the division of 387153 by 18 
We want to divide 387153 by 18.

Step 1:
If we divide 3 by 18, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 18

Let's proceed to step 2:
38 divided by 18 is 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 36 from 38 to get 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 18

Let's proceed to step 3:
If we divide 27 by 18, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtract 18 from 27 to get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 18

Step 4:
91 divided by 18 is 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 215.0
Deduct 90 from 91 and we're left with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 18

Advancing to step 5:
When dividing 15 by 18, we get 0 with a remainder of 15.
The next digit of our result is 0. 
Result so far: 2150.0
Subtracting 0 from 15 leaves us with 15.
Take the next digit (3) from the dividend and append it to 15, then repeat: 153 / 18

Moving on to step 6:
The number 18 fits into 153 8 times, leaving a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 21508.0
Deduct 144 from 153 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
18 goes into 90 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 21508.5
Subtract 90 from 90 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
18 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 21508.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
18 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 21508.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 21508.5, with a leftover of 0.0.
