744631 ÷ 40 
We want to divide 744631 by 40.

Moving on to step 1:
40 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 40

Advancing to step 2:
40 can be fit into 74 1 times, resulting in a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 40 from 74, we get 34.
Fetch the next digit (4) from the dividend, attach it to 34 and continue: 344 / 40

Advancing to step 3:
344 divided by 40 is 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 18.0
The remainder is 24 after subtracting 320 from 344.
Include the next digit (6) from the dividend after 24, then repeat: 246 / 40

On to step 4:
The number 40 fits into 246 6 times, leaving a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 186.0
The remainder is 6 after subtracting 240 from 246.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 40

Advancing to step 5:
40 can be fit into 63 1 times, resulting in a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 1861.0
Deduct 40 from 63 and we're left with 23.
Include the next digit (1) from the dividend after 23, then repeat: 231 / 40

Let's proceed to step 6:
If we divide 231 by 40, we get 5 and a remainder of 31.
The number 5 becomes the next digit in our result. 
Result so far: 18615.0
Subtract 200 from 231 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 7:
If we divide 310 by 40, we get 7 and a remainder of 30.
The number 7 becomes the next digit in our result. 
Result so far: 18615.7
Subtract 280 from 310 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
When dividing 300 by 40, we get 7 with a remainder of 20.
The next digit of our result is 7. 
Result so far: 18615.77
Deduct 280 from 300 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.

The final outcome is 18615.77, with a leftover of 0.02.
