745687 ÷ 40 
Let's see how many times 40 fits into 745687.

Step 1:
If we divide 7 by 40, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 40

On to step 2:
40 goes into 74 1 times with a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 40 from 74 to get 34.
Take the next digit (5) from the dividend and append it to 34, then repeat: 345 / 40

Moving on to step 3:
When dividing 345 by 40, we get 8 with a remainder of 25.
The next digit of our result is 8. 
Result so far: 18.0
Subtracting 320 from 345 leaves us with 25.
Fetch the next digit (6) from the dividend, attach it to 25 and continue: 256 / 40

Step 4:
When dividing 256 by 40, we get 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 186.0
Subtract 240 from 256 to get 16.
Grab the next digit (8) from the dividend, add it to 16, then carry on: 168 / 40

Moving on to step 5:
When dividing 168 by 40, we get 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 1864.0
The remainder is 8 after subtracting 160 from 168.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 40

Let's proceed to step 6:
40 can be fit into 87 2 times, resulting in a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 18642.0
If we take 80 away from 87, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
The number 40 fits into 70 1 times, leaving a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 18642.1
Deduct 40 from 70 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
When dividing 300 by 40, we get 7 with a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 18642.17
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.

Advancing to step 9:
200 divided by 40 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 18642.175
If we subtract 200 from 200, we 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.

Let's proceed to step 10:
40 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 18642.175
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.

On to step 11:
40 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 18642.175
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.

The quotient of the division is 18642.175, and the remainder is 0.0.
