679729 divided by 40 
We want to divide 679729 by 40.

Going ahead to step 1:
When dividing 6 by 40, we get 0 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.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 40

Going ahead to step 2:
67 divided by 40 is 1 with a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 40 away from 67, we end up with 27.
Take the next digit (9) from the dividend and append it to 27, then repeat: 279 / 40

Let's proceed to step 3:
If we divide 279 by 40, we get 6 and a remainder of 39.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we subtract 240 from 279, we get 39.
Take the next digit (7) from the dividend and append it to 39, then repeat: 397 / 40

Moving on to step 4:
If we divide 397 by 40, we get 9 and a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 169.0
Subtract 360 from 397 to get 37.
Take the next digit (2) from the dividend and append it to 37, then repeat: 372 / 40

Going ahead to step 5:
372 divided by 40 is 9 with a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 1699.0
Deduct 360 from 372 and we're left with 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 40

Advancing to step 6:
The number 40 fits into 129 3 times, leaving a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 16993.0
If we subtract 120 from 129, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
When dividing 90 by 40, we get 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 16993.2
If we subtract 80 from 90, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
40 can be fit into 100 2 times, resulting in a remainder of 20.
The next digit of our result is 2. 
Result so far: 16993.22
If we take 80 away from 100, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 16993.22, with a leftover of 0.02.
