Let's divide 600668 by 40
Our goal is to divide 600668 by 40.

Going ahead to step 1:
When dividing 6 by 40, we get 0 with 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.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 40

Going ahead to step 2:
40 goes into 60 1 times with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 40 from 60 to get 20.
Fetch the next digit (0) from the dividend, attach it to 20 and continue: 200 / 40

On to step 3:
The number 40 fits into 200 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 200 from 200 and we're left with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 40

Moving on to step 4:
40 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 150.0
If we take 0 away from 6, we end up with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 40

Let's proceed to step 5:
The number 40 fits into 66 1 times, leaving a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 1501.0
The remainder is 26 after subtracting 40 from 66.
Include the next digit (8) from the dividend after 26, then repeat: 268 / 40

Going ahead to step 6:
40 can be fit into 268 6 times, resulting in a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 15016.0
Deduct 240 from 268 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 7:
When dividing 280 by 40, we get 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 15016.7
Deduct 280 from 280 and we're left 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.

Let's proceed to step 8:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15016.7
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.

Advancing 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: 15016.7
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.

After the division, we end up with 15016.7 and a remainder of 0.0.
