6 divided by 453 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 453

Let's proceed to step 2:
65 divided by 453 is 0 with a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Bring next digit (8) of the dividend behind the 65 and repeat the process: 658 / 453

Step 3:
The number 453 fits into 658 1 times, leaving a remainder of 205.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 453 from 658 and we're left with 205.
Fetch the next digit (3) from the dividend, attach it to 205 and continue: 2053 / 453

Moving on to step 4:

Use 4 as the next digit of our solution. 
Result so far: 14.0
If we subtract 1812 from 2053, we get 241.
Append the next digit (8) from the dividend to 241 and continue with: 2418 / 453

On to step 5:
453 can be fit into 2418 5 times, resulting in a remainder of 153.
Put 5 as the next digit of the answer. 
Result so far: 145.0
Subtract 2265 from 2418 to get 153.
Bring next digit (6) of the dividend behind the 153 and repeat the process: 1536 / 453

Moving on to step 6:
The number 453 fits into 1536 3 times, leaving a remainder of 177.
Record the quotient 3 as the next digit in the result. 
Result so far: 1453.0
If we subtract 1359 from 1536, we get 177.
Take the next digit (2) from the dividend and append it to 177, then repeat: 1772 / 453

Let's proceed to step 7:
When dividing 1772 by 453, we get 3 with a remainder of 413.
Use 3 as the next digit of our solution. 
Result so far: 14533.0
If we subtract 1359 from 1772, we get 413.
Grab the next digit (1) from the dividend, add it to 413, then carry on: 4131 / 453

On to step 8:
The number 453 fits into 4131 9 times, leaving a remainder of 54.
The next digit of our result is 9. 
Result so far: 145339.0
Subtract 4077 from 4131 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 9:
540 divided by 453 is 1 with a remainder of 87.
Put 1 as the next digit of the answer. 
Result so far: 145339.1
If we subtract 453 from 540, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 10:
870 divided by 453 is 1 with a remainder of 417.
Write down 1 as next digit of the result. 
Result so far: 145339.11
Subtracting 453 from 870 leaves us with 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Our division results in 145339.11 with a remaining 0.417.
