We look at the division of 669592 by 40 
We want to divide 669592 by 40.

Advancing 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
Subtract 0 from 6 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 40

Moving on to step 2:
If we divide 66 by 40, we get 1 and a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 40 away from 66, we end up with 26.
Append the next digit (9) from the dividend to 26 and continue with: 269 / 40

Step 3:
269 divided by 40 is 6 with a remainder of 29.
Write down 6 as next digit of the result. 
Result so far: 16.0
Deduct 240 from 269 and we're left with 29.
Fetch the next digit (5) from the dividend, attach it to 29 and continue: 295 / 40

Advancing to step 4:
When dividing 295 by 40, we get 7 with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 167.0
If we subtract 280 from 295, we get 15.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 40

Advancing to step 5:
The number 40 fits into 159 3 times, leaving a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 1673.0
If we subtract 120 from 159, we get 39.
Bring next digit (2) of the dividend behind the 39 and repeat the process: 392 / 40

Let's proceed to step 6:
392 divided by 40 is 9 with a remainder of 32.
The number 9 becomes the next digit in our result. 
Result so far: 16739.0
If we take 360 away from 392, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 7:
If we divide 320 by 40, we get 8 and a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 16739.8
Subtracting 320 from 320 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.

Let's proceed to step 8:
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: 16739.8
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:
40 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 16739.8
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.

The final outcome is 16739.8, with a leftover of 0.0.
