690687 divided by 40 
Our goal is to divide 690687 by 40.

Let's proceed to step 1:
40 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 40

Step 2:
The number 40 fits into 69 1 times, leaving a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 40 from 69 and we're left with 29.
Take the next digit (0) from the dividend and append it to 29, then repeat: 290 / 40

Moving on to step 3:
The number 40 fits into 290 7 times, leaving a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we subtract 280 from 290, we get 10.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 40

Going ahead to step 4:
40 can be fit into 106 2 times, resulting in a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 172.0
Subtract 80 from 106 to get 26.
Include the next digit (8) from the dividend after 26, then repeat: 268 / 40

Let's proceed to step 5:
268 divided by 40 is 6 with a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 1726.0
Subtracting 240 from 268 leaves us with 28.
Grab the next digit (7) from the dividend, add it to 28, then carry on: 287 / 40

Going ahead to step 6:
If we divide 287 by 40, we get 7 and a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 17267.0
If we take 280 away from 287, 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.

Advancing to step 7:
40 can be fit into 70 1 times, resulting in a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 17267.1
Subtracting 40 from 70 leaves us 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.

Let's proceed to step 8:
The number 40 fits into 300 7 times, leaving a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 17267.17
Subtract 280 from 300 to get 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 9:
40 can be fit into 200 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 17267.175
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.

Let's proceed to step 10:
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: 17267.175
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.

Let's proceed to step 11:
When dividing 0 by 40, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 17267.175
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 result is 17267.175 with a remainder of 0.0.
