We divide 39919 by 18
Let's see how many times 18 fits into 39919.

Advancing to step 1:
If we divide 3 by 18, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 18

Step 2:
18 can be fit into 39 2 times, resulting in a remainder of 3.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 3 after subtracting 36 from 39.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 18

Let's proceed to step 3:
39 divided by 18 is 2 with a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Subtract 36 from 39 to get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 18

Step 4:
18 can be fit into 31 1 times, resulting in a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 221.0
Subtracting 18 from 31 leaves us with 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 18

Going ahead to step 5:
18 can be fit into 139 7 times, resulting in a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 2217.0
Subtract 126 from 139 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 6:
When dividing 130 by 18, we get 7 with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 2217.7
Subtract 126 from 130 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
When dividing 40 by 18, we get 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 2217.72
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
The number 18 fits into 40 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 2217.722
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 2217.722, and the remainder is 0.0004.
