Let's divide 40161930 by 680
We're looking to find how many times 680 goes into 40161930.

Let's proceed to step 1:
680 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 680

Step 2:
The number 680 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Include the next digit (1) from the dividend after 40, then repeat: 401 / 680

Going ahead to step 3:
401 divided by 680 is 0 with a remainder of 401.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 401 after subtracting 0 from 401.
Bring next digit (6) of the dividend behind the 401 and repeat the process: 4016 / 680

Let's proceed to step 4:
The number 680 fits into 4016 5 times, leaving a remainder of 616.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 616 after subtracting 3400 from 4016.
Append the next digit (1) from the dividend to 616 and continue with: 6161 / 680

On to step 5:
680 can be fit into 6161 9 times, resulting in a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 59.0
Subtract 6120 from 6161 to get 41.
Append the next digit (9) from the dividend to 41 and continue with: 419 / 680

On to step 6:
680 can be fit into 419 0 times, resulting in a remainder of 419.
Use 0 as the next digit of our solution. 
Result so far: 590.0
If we subtract 0 from 419, we get 419.
Fetch the next digit (3) from the dividend, attach it to 419 and continue: 4193 / 680

Moving on to step 7:
680 goes into 4193 6 times with a remainder of 113.
Record the quotient 6 as the next digit in the result. 
Result so far: 5906.0
Deduct 4080 from 4193 and we're left with 113.
Take the next digit (0) from the dividend and append it to 113, then repeat: 1130 / 680

Step 8:
If we divide 1130 by 680, we get 1 and a remainder of 450.
Use 1 as the next digit of our solution. 
Result so far: 59061.0
Deduct 680 from 1130 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Let's proceed to step 9:
If we divide 4500 by 680, we get 6 and a remainder of 420.
The number 6 becomes the next digit in our result. 
Result so far: 59061.6
Subtract 4080 from 4500 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

On to step 10:
680 goes into 4200 6 times with a remainder of 120.
Write down 6 as next digit of the result. 
Result so far: 59061.66
Subtracting 4080 from 4200 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

In conclusion, the division gives 59061.66 with a balance of 0.12.
