Let's divide 311221 by 454
Let's see how many times 454 fits into 311221.

Going ahead to step 1:
The number 454 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 454

On to step 2:
454 goes into 31 0 times with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Take the next digit (1) from the dividend and append it to 31, then repeat: 311 / 454

Step 3:
311 divided by 454 is 0 with a remainder of 311.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 311 to get 311.
Grab the next digit (2) from the dividend, add it to 311, then carry on: 3112 / 454

Moving on to step 4:
454 goes into 3112 6 times with a remainder of 388.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 2724 away from 3112, we end up with 388.
Include the next digit (2) from the dividend after 388, then repeat: 3882 / 454

Let's proceed to step 5:
3882 divided by 454 is 8 with a remainder of 250.
The next digit of our result is 8. 
Result so far: 68.0
If we take 3632 away from 3882, we end up with 250.
Include the next digit (1) from the dividend after 250, then repeat: 2501 / 454

On to step 6:
2501 divided by 454 is 5 with a remainder of 231.
The next digit of our result is 5. 
Result so far: 685.0
If we subtract 2270 from 2501, we get 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Going ahead to step 7:
454 can be fit into 2310 5 times, resulting in a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 685.5
Deduct 2270 from 2310 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
When dividing 400 by 454, we get 0 with a remainder of 400.
The next digit of our result is 0. 
Result so far: 685.5
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 9:
454 goes into 4000 8 times with a remainder of 368.
Put 8 as the next digit of the answer. 
Result so far: 685.508
Subtract 3632 from 4000 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

On to step 10:
When dividing 3680 by 454, we get 8 with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 685.5088
The remainder is 48 after subtracting 3632 from 3680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 685.5088 and a remainder of 0.00048.
