906404 ÷ 30 
Let's see how many times 30 fits into 906404.

Going ahead to step 1:
When dividing 9 by 30, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 30

Moving on to step 2:
30 goes into 90 3 times with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 90 from 90, we get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 30

Moving on to step 3:
The number 30 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 30.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 30

Going ahead to step 4:
If we divide 64 by 30, we get 2 and a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 302.0
Subtracting 60 from 64 leaves us with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 30

Going ahead to step 5:
When dividing 40 by 30, we get 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 3021.0
Deduct 30 from 40 and we're left with 10.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 30

Moving on to step 6:
30 can be fit into 104 3 times, resulting in a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 30213.0
The remainder is 14 after subtracting 90 from 104.
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:
When dividing 140 by 30, we get 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 30213.4
If we take 120 away from 140, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 30213.46
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
When dividing 200 by 30, we get 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 30213.466
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 30213.466, with a leftover of 0.002.
