Let's divide 688650 by 40
We want to divide 688650 by 40.

Advancing to step 1:
When dividing 6 by 40, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 40

Advancing to step 2:
40 can be fit into 68 1 times, resulting in a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 40 from 68 to get 28.
Take the next digit (8) from the dividend and append it to 28, then repeat: 288 / 40

On to step 3:
The number 40 fits into 288 7 times, leaving a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we take 280 away from 288, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 40

Going ahead to step 4:
If we divide 86 by 40, we get 2 and a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 172.0
Subtract 80 from 86 to get 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 40

Going ahead to step 5:
If we divide 65 by 40, we get 1 and a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 1721.0
Subtract 40 from 65 to get 25.
Fetch the next digit (0) from the dividend, attach it to 25 and continue: 250 / 40

Advancing to step 6:
40 goes into 250 6 times with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 17216.0
The remainder is 10 after subtracting 240 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
If we divide 100 by 40, we get 2 and a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 17216.2
Subtracting 80 from 100 leaves us 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.

Going ahead to step 8:
200 divided by 40 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 17216.25
The remainder is 0 after subtracting 200 from 200.
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 9:
0 divided by 40 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 17216.25
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.

Let's proceed to step 10:
40 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 17216.25
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.

After the division, we end up with 17216.25 and a remainder of 0.0.
