57140042 ÷ 668 
We want to figure out the number of times 57140042 can be divided by 668.

Going ahead to step 1:
5 divided by 668 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 668

Let's proceed to step 2:
668 can be fit into 57 0 times, resulting in a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Fetch the next digit (1) from the dividend, attach it to 57 and continue: 571 / 668

Going ahead to step 3:
668 goes into 571 0 times with a remainder of 571.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 571 and we're left with 571.
Take the next digit (4) from the dividend and append it to 571, then repeat: 5714 / 668

Going ahead to step 4:
5714 divided by 668 is 8 with a remainder of 370.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 5344 from 5714 leaves us with 370.
Take the next digit (0) from the dividend and append it to 370, then repeat: 3700 / 668

Let's proceed to step 5:
3700 divided by 668 is 5 with a remainder of 360.
The next digit of our result is 5. 
Result so far: 85.0
If we subtract 3340 from 3700, we get 360.
Fetch the next digit (0) from the dividend, attach it to 360 and continue: 3600 / 668

On to step 6:
If we divide 3600 by 668, we get 5 and a remainder of 260.
Record the quotient 5 as the next digit in the result. 
Result so far: 855.0
The remainder is 260 after subtracting 3340 from 3600.
Take the next digit (4) from the dividend and append it to 260, then repeat: 2604 / 668

On to step 7:
668 can be fit into 2604 3 times, resulting in a remainder of 600.
Use 3 as the next digit of our solution. 
Result so far: 8553.0
If we take 2004 away from 2604, we end up with 600.
Append the next digit (2) from the dividend to 600 and continue with: 6002 / 668

Step 8:
6002 divided by 668 is 8 with a remainder of 658.
The number 8 becomes the next digit in our result. 
Result so far: 85538.0
The remainder is 658 after subtracting 5344 from 6002.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

On to step 9:
6580 divided by 668 is 9 with a remainder of 568.
Record the quotient 9 as the next digit in the result. 
Result so far: 85538.9
The remainder is 568 after subtracting 6012 from 6580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Moving on to step 10:
If we divide 5680 by 668, we get 8 and a remainder of 336.
Record the quotient 8 as the next digit in the result. 
Result so far: 85538.98
Subtracting 5344 from 5680 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Let's proceed to step 11:
3360 divided by 668 is 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 85538.985
The remainder is 20 after subtracting 3340 from 3360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
668 goes into 200 0 times with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 85538.985
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 13:
668 goes into 2000 2 times with a remainder of 664.
Use 2 as the next digit of our solution. 
Result so far: 85538.98502
If we take 1336 away from 2000, we end up with 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Step 14:
If we divide 6640 by 668, we get 9 and a remainder of 628.
Write down 9 as next digit of the result. 
Result so far: 85538.985029
If we take 6012 away from 6640, we end up with 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Going ahead to step 15:
The number 668 fits into 6280 9 times, leaving a remainder of 268.
Use 9 as the next digit of our solution. 
Result so far: 85538.9850299
The remainder is 268 after subtracting 6012 from 6280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

In conclusion, the division gives 85538.9850299 with a balance of 2.68e-06.
