If we subtract 0 from 3, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 623

Advancing to step 2:
When dividing 39 by 623, we get 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Fetch the next digit (4) from the dividend, attach it to 39 and continue: 394 / 623

Advancing to step 3:
623 goes into 394 0 times with a remainder of 394.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 394, we get 394.
Grab the next digit (6) from the dividend, add it to 394, then carry on: 3946 / 623

Step 4:
3946 divided by 623 is 6 with a remainder of 208.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 208 after subtracting 3738 from 3946.
Append the next digit (3) from the dividend to 208 and continue with: 2083 / 623

Moving on to step 5:
623 goes into 2083 3 times with a remainder of 214.
Write down 3 as next digit of the result. 
Result so far: 63.0
The remainder is 214 after subtracting 1869 from 2083.
Fetch the next digit (7) from the dividend, attach it to 214 and continue: 2147 / 623

On to step 6:
623 goes into 2147 3 times with a remainder of 278.
Record the quotient 3 as the next digit in the result. 
Result so far: 633.0
If we subtract 1869 from 2147, we get 278.
Append the next digit (6) from the dividend to 278 and continue with: 2786 / 623

Advancing to step 7:
623 goes into 2786 4 times with a remainder of 294.
Record the quotient 4 as the next digit in the result. 
Result so far: 6334.0
Subtract 2492 from 2786 to get 294.
Grab the next digit (7) from the dividend, add it to 294, then carry on: 2947 / 623

Step 8:
623 goes into 2947 4 times with a remainder of 455.
The next digit of our result is 4. 
Result so far: 63344.0
The remainder is 455 after subtracting 2492 from 2947.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

On to step 9:
4550 divided by 623 is 7 with a remainder of 189.
Put 7 as the next digit of the answer. 
Result so far: 63344.7
Subtract 4361 from 4550 to get 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

On to step 10:
623 goes into 1890 3 times with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 63344.73
The remainder is 21 after subtracting 1869 from 1890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 11:
The number 623 fits into 210 0 times, leaving a remainder of 210.
Write down 0 as next digit of the result. 
Result so far: 63344.73
Subtracting 0 from 210 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 12:
If we divide 2100 by 623, we get 3 and a remainder of 231.
Use 3 as the next digit of our solution. 
Result so far: 63344.7303
Subtract 1869 from 2100 to 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 13:
623 goes into 2310 3 times with a remainder of 441.
The number 3 becomes the next digit in our result. 
Result so far: 63344.73033
Subtracting 1869 from 2310 leaves us with 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

The final result is 63344.73033 with a remainder of 0.000441.
