679353 ÷ 40 
Our goal is to divide 679353 by 40.

Advancing to step 1:
40 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 40

Let's proceed to step 2:
40 can be fit into 67 1 times, resulting in a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 27 after subtracting 40 from 67.
Include the next digit (9) from the dividend after 27, then repeat: 279 / 40

Advancing to step 3:
40 goes into 279 6 times with a remainder of 39.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtract 240 from 279 to get 39.
Include the next digit (3) from the dividend after 39, then repeat: 393 / 40

Step 4:
40 goes into 393 9 times with a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 169.0
Subtract 360 from 393 to get 33.
Include the next digit (5) from the dividend after 33, then repeat: 335 / 40

Let's proceed to step 5:
335 divided by 40 is 8 with a remainder of 15.
Record the quotient 8 as the next digit in the result. 
Result so far: 1698.0
Subtracting 320 from 335 leaves us with 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 40

Step 6:
40 goes into 153 3 times with a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 16983.0
The remainder is 33 after subtracting 120 from 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 7:
40 can be fit into 330 8 times, resulting in a remainder of 10.
The next digit of our result is 8. 
Result so far: 16983.8
If we take 320 away from 330, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
40 can be fit into 100 2 times, resulting in a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 16983.82
The remainder is 20 after subtracting 80 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
200 divided by 40 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 16983.825
If we take 200 away from 200, 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.

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: 16983.825
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.

Advancing to step 11:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 16983.825
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.

After the division, we end up with 16983.825 and a remainder of 0.0.
