19969574 ÷ 668 
We want to divide 19969574 by 668.

On to step 1:
1 divided by 668 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 668

Advancing to step 2:
The number 668 fits into 19 0 times, leaving a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Take the next digit (9) from the dividend and append it to 19, then repeat: 199 / 668

Going ahead to step 3:
668 goes into 199 0 times with a remainder of 199.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 199, we end up with 199.
Fetch the next digit (6) from the dividend, attach it to 199 and continue: 1996 / 668

Step 4:
668 can be fit into 1996 2 times, resulting in a remainder of 660.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 1336 from 1996 leaves us with 660.
Fetch the next digit (9) from the dividend, attach it to 660 and continue: 6609 / 668

Moving on to step 5:
668 can be fit into 6609 9 times, resulting in a remainder of 597.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Subtracting 6012 from 6609 leaves us with 597.
Fetch the next digit (5) from the dividend, attach it to 597 and continue: 5975 / 668

Step 6:
When dividing 5975 by 668, we get 8 with a remainder of 631.
Write down 8 as next digit of the result. 
Result so far: 298.0
Subtract 5344 from 5975 to get 631.
Bring next digit (7) of the dividend behind the 631 and repeat the process: 6317 / 668

Moving on to step 7:
When dividing 6317 by 668, we get 9 with a remainder of 305.
The number 9 becomes the next digit in our result. 
Result so far: 2989.0
Subtract 6012 from 6317 to get 305.
Include the next digit (4) from the dividend after 305, then repeat: 3054 / 668

Let's proceed to step 8:
When dividing 3054 by 668, we get 4 with a remainder of 382.
Put 4 as the next digit of the answer. 
Result so far: 29894.0
Deduct 2672 from 3054 and we're left with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Moving on to step 9:
668 can be fit into 3820 5 times, resulting in a remainder of 480.
Use 5 as the next digit of our solution. 
Result so far: 29894.5
Subtracting 3340 from 3820 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 10:
668 can be fit into 4800 7 times, resulting in a remainder of 124.
Put 7 as the next digit of the answer. 
Result so far: 29894.57
Subtract 4676 from 4800 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Moving on to step 11:
If we divide 1240 by 668, we get 1 and a remainder of 572.
Put 1 as the next digit of the answer. 
Result so far: 29894.571
The remainder is 572 after subtracting 668 from 1240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

On to step 12:
668 goes into 5720 8 times with a remainder of 376.
The next digit of our result is 8. 
Result so far: 29894.5718
Subtract 5344 from 5720 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Let's proceed to step 13:
When dividing 3760 by 668, we get 5 with a remainder of 420.
The number 5 becomes the next digit in our result. 
Result so far: 29894.57185
If we take 3340 away from 3760, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 14:
If we divide 4200 by 668, we get 6 and a remainder of 192.
Use 6 as the next digit of our solution. 
Result so far: 29894.571856
If we take 4008 away from 4200, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 15:
The number 668 fits into 1920 2 times, leaving a remainder of 584.
Put 2 as the next digit of the answer. 
Result so far: 29894.5718562
The remainder is 584 after subtracting 1336 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Advancing to step 16:
When dividing 5840 by 668, we get 8 with a remainder of 496.
Write down 8 as next digit of the result. 
Result so far: 29894.57185628
The remainder is 496 after subtracting 5344 from 5840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

The final result is 29894.57185628 with a remainder of 4.96e-07.
