We're dividing 669616 by 40 
We're looking to find how many times 40 goes into 669616.

Let's proceed to step 1:
The number 40 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 40

Step 2:
If we divide 66 by 40, we get 1 and a remainder of 26.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 26 after subtracting 40 from 66.
Include the next digit (9) from the dividend after 26, then repeat: 269 / 40

Advancing to step 3:
269 divided by 40 is 6 with a remainder of 29.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we take 240 away from 269, we end up with 29.
Fetch the next digit (6) from the dividend, attach it to 29 and continue: 296 / 40

Advancing to step 4:
296 divided by 40 is 7 with a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 167.0
Deduct 280 from 296 and we're left with 16.
Bring next digit (1) of the dividend behind the 16 and repeat the process: 161 / 40

Going ahead to step 5:
When dividing 161 by 40, we get 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 1674.0
Deduct 160 from 161 and we're left with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 40

Moving on to step 6:
40 can be fit into 16 0 times, resulting in a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 16740.0
If we take 0 away from 16, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
If we divide 160 by 40, we get 4 and a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 16740.4
The remainder is 0 after subtracting 160 from 160.
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:
When dividing 0 by 40, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 16740.4
If we subtract 0 from 0, 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.

Step 9:
0 divided by 40 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 16740.4
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 16740.4 with a balance of 0.0.
