We divide 409937 by 18
We want to figure out the number of times 409937 can be divided by 18.

Let's proceed to step 1:
18 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 18

Step 2:
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: 2.0
Subtracting 36 from 40 leaves us with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 18

Let's proceed to step 3:
If we divide 49 by 18, we get 2 and a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 22.0
If we subtract 36 from 49, we get 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 18

Step 4:
If we divide 139 by 18, we get 7 and a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 227.0
If we take 126 away from 139, we end up with 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 18

Let's proceed to step 5:
133 divided by 18 is 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 2277.0
Subtract 126 from 133 to get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 18

Moving on to step 6:
18 goes into 77 4 times with a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 22774.0
If we subtract 72 from 77, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
If we divide 50 by 18, we get 2 and a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 22774.2
If we take 36 away from 50, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
140 divided by 18 is 7 with a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 22774.27
If we subtract 126 from 140, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
If we divide 140 by 18, we get 7 and a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 22774.277
If we subtract 126 from 140, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 22774.277, with a leftover of 0.0014.
