We divide 18043087 by 3
We want to divide 18043087 by 3.

Going ahead to step 1:
When dividing 1 by 3, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 3

Moving on to step 2:
If we divide 18 by 3, we get 6 and a remainder of 0.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 18 from 18 and we're left with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 3

Advancing to step 3:
If we divide 0 by 3, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 60.0
The remainder is 0 after subtracting 0 from 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 3

Let's proceed to step 4:
3 goes into 4 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 601.0
Subtracting 3 from 4 leaves us with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 3

Advancing to step 5:
3 can be fit into 13 4 times, resulting in a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 6014.0
If we subtract 12 from 13, we get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 3

Going ahead to step 6:
The number 3 fits into 10 3 times, leaving a remainder of 1.
The next digit of our result is 3. 
Result so far: 60143.0
Deduct 9 from 10 and we're left with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 3

Step 7:
When dividing 18 by 3, we get 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 601436.0
If we take 18 away from 18, we end up with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 3

Advancing to step 8:
3 can be fit into 7 2 times, resulting in a remainder of 1.
The next digit of our result is 2. 
Result so far: 6014362.0
If we subtract 6 from 7, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
3 can be fit into 10 3 times, resulting in a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 6014362.3
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 10:
3 can be fit into 10 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 6014362.33
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 6014362.33, and the remainder is 0.001.
