680125 ÷ 40 
We want to divide 680125 by 40.

Let's proceed to step 1:
6 divided by 40 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 40

Moving on to step 2:
40 goes into 68 1 times with a remainder of 28.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 28 after subtracting 40 from 68.
Take the next digit (0) from the dividend and append it to 28, then repeat: 280 / 40

Moving on to step 3:
When dividing 280 by 40, we get 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 17.0
If we take 280 away from 280, we end up with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 40

Going ahead to step 4:
The number 40 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 170.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 40

Going ahead to step 5:
40 can be fit into 12 0 times, resulting in a remainder of 12.
The next digit of our result is 0. 
Result so far: 1700.0
Subtract 0 from 12 to get 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 40

Step 6:
The number 40 fits into 125 3 times, leaving a remainder of 5.
The next digit of our result is 3. 
Result so far: 17003.0
If we take 120 away from 125, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
When dividing 50 by 40, we get 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 17003.1
Subtracting 40 from 50 leaves us 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.

Advancing 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: 17003.12
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.

Step 9:
When dividing 200 by 40, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 17003.125
Deduct 200 from 200 and we're left 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.

Step 10:
The number 40 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 17003.125
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.

Advancing to step 11:
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: 17003.125
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 result is 17003.125 with a remainder of 0.0.
