623304 ÷ 40 
We want to divide 623304 by 40.

Going ahead to step 1:
The number 40 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 40

On to step 2:
40 can be fit into 62 1 times, resulting in a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 40 away from 62, we end up with 22.
Include the next digit (3) from the dividend after 22, then repeat: 223 / 40

Step 3:
When dividing 223 by 40, we get 5 with a remainder of 23.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we subtract 200 from 223, we get 23.
Grab the next digit (3) from the dividend, add it to 23, then carry on: 233 / 40

On to step 4:
233 divided by 40 is 5 with a remainder of 33.
Write down 5 as next digit of the result. 
Result so far: 155.0
Subtract 200 from 233 to get 33.
Bring next digit (0) of the dividend behind the 33 and repeat the process: 330 / 40

Moving on to step 5:
40 can be fit into 330 8 times, resulting in a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 1558.0
Subtracting 320 from 330 leaves us with 10.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 40

Let's proceed to step 6:
104 divided by 40 is 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 15582.0
Deduct 80 from 104 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 7:
40 can be fit into 240 6 times, resulting in a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 15582.6
The remainder is 0 after subtracting 240 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
40 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15582.6
Subtracting 0 from 0 leaves us with 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 9:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15582.6
If we take 0 away from 0, we end up with 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 outcome is 15582.6, with a leftover of 0.0.
