417539 ÷ 9 
Let's see how many times 9 fits into 417539.

Advancing to step 1:
If we divide 4 by 9, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 9

Going ahead to step 2:
If we divide 41 by 9, we get 4 and a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 36 from 41 leaves us with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 9

Advancing to step 3:
If we divide 57 by 9, we get 6 and a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 46.0
Subtract 54 from 57 to get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 9

Moving on to step 4:
9 can be fit into 35 3 times, resulting in a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 463.0
If we subtract 27 from 35, we get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 9

Advancing to step 5:
9 can be fit into 83 9 times, resulting in a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 4639.0
Subtracting 81 from 83 leaves us with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 9

Going ahead to step 6:
When dividing 29 by 9, we get 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 46393.0
The remainder is 2 after subtracting 27 from 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
If we divide 20 by 9, we get 2 and a remainder of 2.
The next digit of our result is 2. 
Result so far: 46393.2
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
9 goes into 20 2 times with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 46393.22
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 46393.22, with a leftover of 0.002.
