405650 ÷ 30 
We want to divide 405650 by 30.

Advancing to step 1:
The number 30 fits into 4 0 times, leaving 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.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 30

Advancing to step 2:
40 divided by 30 is 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 30 from 40, we get 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 30

On to step 3:
When dividing 105 by 30, we get 3 with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtract 90 from 105 to get 15.
Include the next digit (6) from the dividend after 15, then repeat: 156 / 30

Going ahead to step 4:
If we divide 156 by 30, we get 5 and a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 135.0
Subtract 150 from 156 to get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 30

Advancing to step 5:
65 divided by 30 is 2 with a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 1352.0
Deduct 60 from 65 and we're left with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 30

Going ahead to step 6:
If we divide 50 by 30, we get 1 and a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 13521.0
If we take 30 away from 50, 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.

Moving on to step 7:
When dividing 200 by 30, we get 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 13521.6
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
If we divide 200 by 30, we get 6 and a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 13521.66
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 13521.66, with a leftover of 0.02.
