556401 ÷ 30 
We want to divide 556401 by 30.

Moving on to step 1:
If we divide 5 by 30, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 30

Let's proceed to step 2:
The number 30 fits into 55 1 times, leaving a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 25 after subtracting 30 from 55.
Take the next digit (6) from the dividend and append it to 25, then repeat: 256 / 30

On to step 3:
256 divided by 30 is 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
The remainder is 16 after subtracting 240 from 256.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 30

Advancing to step 4:
When dividing 164 by 30, we get 5 with a remainder of 14.
Use 5 as the next digit of our solution. 
Result so far: 185.0
The remainder is 14 after subtracting 150 from 164.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 30

Going ahead to step 5:
If we divide 140 by 30, we get 4 and a remainder of 20.
The next digit of our result is 4. 
Result so far: 1854.0
The remainder is 20 after subtracting 120 from 140.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 30

Moving on to step 6:
The number 30 fits into 201 6 times, leaving a remainder of 21.
Put 6 as the next digit of the answer. 
Result so far: 18546.0
If we subtract 180 from 201, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 7:
30 can be fit into 210 7 times, resulting in a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 18546.7
The remainder is 0 after subtracting 210 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
0 divided by 30 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 18546.7
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 18546.7
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 18546.7 with a remainder of 0.0.
