We're dividing 623426 by 40 
We want to divide 623426 by 40.

Going ahead to step 1:
40 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 40

On to step 2:
If we divide 62 by 40, we get 1 and a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 40 from 62 to get 22.
Grab the next digit (3) from the dividend, add it to 22, then carry on: 223 / 40

Step 3:
If we divide 223 by 40, we get 5 and a remainder of 23.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 200 from 223, we get 23.
Fetch the next digit (4) from the dividend, attach it to 23 and continue: 234 / 40

On to step 4:
234 divided by 40 is 5 with a remainder of 34.
The next digit of our result is 5. 
Result so far: 155.0
If we take 200 away from 234, we end up with 34.
Append the next digit (2) from the dividend to 34 and continue with: 342 / 40

Step 5:
342 divided by 40 is 8 with a remainder of 22.
The next digit of our result is 8. 
Result so far: 1558.0
Deduct 320 from 342 and we're left with 22.
Fetch the next digit (6) from the dividend, attach it to 22 and continue: 226 / 40

Step 6:
40 can be fit into 226 5 times, resulting in a remainder of 26.
The number 5 becomes the next digit in our result. 
Result so far: 15585.0
The remainder is 26 after subtracting 200 from 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 7:
260 divided by 40 is 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 15585.6
Deduct 240 from 260 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
40 goes into 200 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 15585.65
Subtract 200 from 200 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
The number 40 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 15585.65
The remainder is 0 after subtracting 0 from 0.
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 10:
If we divide 0 by 40, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15585.65
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 15585.65 with a balance of 0.0.
