Let's divide 407048 by 18
We're looking to find how many times 18 goes into 407048.

Step 1:
The number 18 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 18

Step 2:
The number 18 fits into 40 2 times, leaving a remainder of 4.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 36 from 40, we get 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 18

Advancing to step 3:
18 can be fit into 47 2 times, resulting in a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Subtracting 36 from 47 leaves us with 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 18

On to step 4:
18 goes into 110 6 times with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 226.0
The remainder is 2 after subtracting 108 from 110.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 18

Step 5:
18 goes into 24 1 times with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 2261.0
If we take 18 away from 24, we end up with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 18

On to step 6:
68 divided by 18 is 3 with a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 22613.0
The remainder is 14 after subtracting 54 from 68.
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 7:
18 can be fit into 140 7 times, resulting in a remainder of 14.
The next digit of our result is 7. 
Result so far: 22613.7
The remainder is 14 after subtracting 126 from 140.
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 8:
If we divide 140 by 18, we get 7 and a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 22613.77
The remainder is 14 after subtracting 126 from 140.
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 22613.77, with a leftover of 0.014.
