We're dividing 3489693 by 18 
Our goal is to divide 3489693 by 18.

On to step 1:
The number 18 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 18

Advancing to step 2:
34 divided by 18 is 1 with a remainder of 16.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 18 from 34 and we're left with 16.
Grab the next digit (8) from the dividend, add it to 16, then carry on: 168 / 18

Step 3:
18 can be fit into 168 9 times, resulting in a remainder of 6.
The next digit of our result is 9. 
Result so far: 19.0
Subtract 162 from 168 to get 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 18

Moving on to step 4:
When dividing 69 by 18, we get 3 with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 193.0
Subtract 54 from 69 to get 15.
Append the next digit (6) from the dividend to 15 and continue with: 156 / 18

Moving on to step 5:
If we divide 156 by 18, we get 8 and a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 1938.0
If we take 144 away from 156, we end up with 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 18

Step 6:
18 can be fit into 129 7 times, resulting in a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 19387.0
Subtract 126 from 129 to get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 18

Step 7:
33 divided by 18 is 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 193871.0
Deduct 18 from 33 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 8:
18 goes into 150 8 times with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 193871.8
Subtract 144 from 150 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
18 can be fit into 60 3 times, resulting in a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 193871.83
The remainder is 6 after subtracting 54 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
The number 18 fits into 60 3 times, leaving a remainder of 6.
The next digit of our result is 3. 
Result so far: 193871.833
Subtract 54 from 60 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The quotient of the division is 193871.833, and the remainder is 0.0006.
