Let's divide 668868 by 40
Our goal is to divide 668868 by 40.

Let's proceed to step 1:
6 divided by 40 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 40

Advancing to step 2:
40 goes into 66 1 times with a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 40 away from 66, we end up with 26.
Bring next digit (8) of the dividend behind the 26 and repeat the process: 268 / 40

Advancing to step 3:
When dividing 268 by 40, we get 6 with a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 16.0
The remainder is 28 after subtracting 240 from 268.
Take the next digit (8) from the dividend and append it to 28, then repeat: 288 / 40

On to step 4:
40 can be fit into 288 7 times, resulting in a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 167.0
Subtracting 280 from 288 leaves us with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 40

Advancing to step 5:
86 divided by 40 is 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 1672.0
If we take 80 away from 86, we end up with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 40

Going ahead to step 6:
The number 40 fits into 68 1 times, leaving a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 16721.0
If we subtract 40 from 68, we get 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: 16721.7
Subtracting 280 from 280 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 8:
40 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 16721.7
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.

Advancing to step 9:
40 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 16721.7
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.

The final outcome is 16721.7, with a leftover of 0.0.
