Let's divide 688587 by 40
Our goal is to divide 688587 by 40.

On to step 1:
40 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 40

Moving on to step 2:
68 divided by 40 is 1 with a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 40 from 68 and we're left with 28.
Take the next digit (8) from the dividend and append it to 28, then repeat: 288 / 40

Advancing to step 3:
288 divided by 40 is 7 with a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
The remainder is 8 after subtracting 280 from 288.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 40

Moving on to step 4:
The number 40 fits into 85 2 times, leaving a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 172.0
Deduct 80 from 85 and we're left with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 40

On to step 5:
58 divided by 40 is 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 1721.0
Subtract 40 from 58 to get 18.
Take the next digit (7) from the dividend and append it to 18, then repeat: 187 / 40

Advancing to step 6:
If we divide 187 by 40, we get 4 and a remainder of 27.
Use 4 as the next digit of our solution. 
Result so far: 17214.0
Subtracting 160 from 187 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 7:
If we divide 270 by 40, we get 6 and a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 17214.6
Subtract 240 from 270 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.

Advancing to step 8:
300 divided by 40 is 7 with a remainder of 20.
The next digit of our result is 7. 
Result so far: 17214.67
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:
40 can be fit into 200 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 17214.675
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.

Moving on to step 10:
If we divide 0 by 40, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 17214.675
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.

Moving on to step 11:
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: 17214.675
Subtract 0 from 0 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.

In conclusion, the division gives 17214.675 with a balance of 0.0.
