6453 ÷ 30 
We want to divide 6453 by 30.

Going ahead to step 1:
The number 30 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 30

Advancing to step 2:
64 divided by 30 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 60 from 64, we get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 30

On to step 3:
30 can be fit into 45 1 times, resulting in a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we take 30 away from 45, we end up with 15.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 30

Let's proceed to step 4:
30 goes into 153 5 times with a remainder of 3.
The next digit of our result is 5. 
Result so far: 215.0
The remainder is 3 after subtracting 150 from 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 5:
30 divided by 30 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 215.1
The remainder is 0 after subtracting 30 from 30.
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 6:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 215.1
If we subtract 0 from 0, we 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.

Step 7:
When dividing 0 by 30, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 215.1
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.

The final result is 215.1 with a remainder of 0.0.
