Let's divide 284421 by 623
We're looking to find how many times 623 goes into 284421.

Going ahead to step 1:
The number 623 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 623

Advancing to step 2:
623 goes into 28 0 times with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Fetch the next digit (4) from the dividend, attach it to 28 and continue: 284 / 623

Advancing to step 3:
If we divide 284 by 623, we get 0 and a remainder of 284.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 284, we end up with 284.
Grab the next digit (4) from the dividend, add it to 284, then carry on: 2844 / 623

Step 4:
The number 623 fits into 2844 4 times, leaving a remainder of 352.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 2492 from 2844, we get 352.
Take the next digit (2) from the dividend and append it to 352, then repeat: 3522 / 623

Advancing to step 5:
623 can be fit into 3522 5 times, resulting in a remainder of 407.
The next digit of our result is 5. 
Result so far: 45.0
If we take 3115 away from 3522, we end up with 407.
Include the next digit (1) from the dividend after 407, then repeat: 4071 / 623

On to step 6:
4071 divided by 623 is 6 with a remainder of 333.
Put 6 as the next digit of the answer. 
Result so far: 456.0
Deduct 3738 from 4071 and we're left with 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Going ahead to step 7:
When dividing 3330 by 623, we get 5 with a remainder of 215.
Record the quotient 5 as the next digit in the result. 
Result so far: 456.5
If we subtract 3115 from 3330, we get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Advancing to step 8:
623 can be fit into 2150 3 times, resulting in a remainder of 281.
Write down 3 as next digit of the result. 
Result so far: 456.53
Subtracting 1869 from 2150 leaves us with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Going ahead to step 9:
623 goes into 2810 4 times with a remainder of 318.
Write down 4 as next digit of the result. 
Result so far: 456.534
Subtract 2492 from 2810 to get 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

On to step 10:
If we divide 3180 by 623, we get 5 and a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 456.5345
The remainder is 65 after subtracting 3115 from 3180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 11:
623 goes into 650 1 times with a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 456.53451
If we subtract 623 from 650, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 12:
270 divided by 623 is 0 with a remainder of 270.
Write down 0 as next digit of the result. 
Result so far: 456.53451
Subtract 0 from 270 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 13:
The number 623 fits into 2700 4 times, leaving a remainder of 208.
The next digit of our result is 4. 
Result so far: 456.5345104
The remainder is 208 after subtracting 2492 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Going ahead to step 14:
When dividing 2080 by 623, we get 3 with a remainder of 211.
Record the quotient 3 as the next digit in the result. 
Result so far: 456.53451043
If we subtract 1869 from 2080, we get 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Our division results in 456.53451043 with a remaining 2.11e-07.
