We're dividing 139385 by 18 
We want to divide 139385 by 18.

Let's proceed to step 1:
1 divided by 18 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 18

On to step 2:
The number 18 fits into 13 0 times, leaving a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 18

Advancing to step 3:
The number 18 fits into 139 7 times, leaving a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 126 away from 139, we end up with 13.
Bring next digit (3) of the dividend behind the 13 and repeat the process: 133 / 18

Step 4:
When dividing 133 by 18, we get 7 with a remainder of 7.
The next digit of our result is 7. 
Result so far: 77.0
Subtracting 126 from 133 leaves us with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 18

Advancing to step 5:
If we divide 78 by 18, we get 4 and a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 774.0
If we take 72 away from 78, we end up with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 18

Let's proceed to step 6:
If we divide 65 by 18, we get 3 and a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 7743.0
Subtract 54 from 65 to get 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 can be fit into 110 6 times, resulting in a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 7743.6
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.

On to step 8:
18 goes into 20 1 times with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 7743.61
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.

Step 9:
When dividing 20 by 18, we get 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 7743.611
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 quotient of the division is 7743.611, and the remainder is 0.0002.
