Let's divide 138953 by 18
We want to divide 138953 by 18.

Advancing to step 1:
When dividing 1 by 18, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 18

On to step 2:
If we divide 13 by 18, we get 0 and a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 18

Moving on to step 3:
18 goes into 138 7 times with a remainder of 12.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 12 after subtracting 126 from 138.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 18

Going ahead to step 4:
When dividing 129 by 18, we get 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 77.0
Subtracting 126 from 129 leaves us with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 18

On to step 5:
When dividing 35 by 18, we get 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 771.0
Subtract 18 from 35 to get 17.
Grab the next digit (3) from the dividend, add it to 17, then carry on: 173 / 18

Step 6:
If we divide 173 by 18, we get 9 and a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 7719.0
Subtracting 162 from 173 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
18 goes into 110 6 times with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 7719.6
The remainder is 2 after subtracting 108 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
18 can be fit into 20 1 times, resulting in a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 7719.61
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
18 goes into 20 1 times with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 7719.611
Subtracting 18 from 20 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 7719.611, with a leftover of 0.0002.
