We divide 19967914 by 660
We want to figure out the number of times 19967914 can be divided by 660.

Moving on to step 1:
The number 660 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 660

On to step 2:
If we divide 19 by 660, we get 0 and a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 660

Let's proceed to step 3:
199 divided by 660 is 0 with a remainder of 199.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 199, we get 199.
Take the next digit (6) from the dividend and append it to 199, then repeat: 1996 / 660

Going ahead to step 4:
When dividing 1996 by 660, we get 3 with a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 16 after subtracting 1980 from 1996.
Fetch the next digit (7) from the dividend, attach it to 16 and continue: 167 / 660

Let's proceed to step 5:
167 divided by 660 is 0 with a remainder of 167.
Write down 0 as next digit of the result. 
Result so far: 30.0
The remainder is 167 after subtracting 0 from 167.
Bring next digit (9) of the dividend behind the 167 and repeat the process: 1679 / 660

Step 6:
1679 divided by 660 is 2 with a remainder of 359.
Record the quotient 2 as the next digit in the result. 
Result so far: 302.0
Subtract 1320 from 1679 to get 359.
Grab the next digit (1) from the dividend, add it to 359, then carry on: 3591 / 660

Advancing to step 7:
660 can be fit into 3591 5 times, resulting in a remainder of 291.
Write down 5 as next digit of the result. 
Result so far: 3025.0
Subtract 3300 from 3591 to get 291.
Fetch the next digit (4) from the dividend, attach it to 291 and continue: 2914 / 660

On to step 8:
When dividing 2914 by 660, we get 4 with a remainder of 274.
The number 4 becomes the next digit in our result. 
Result so far: 30254.0
Subtracting 2640 from 2914 leaves us with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Step 9:
When dividing 2740 by 660, we get 4 with a remainder of 100.
Write down 4 as next digit of the result. 
Result so far: 30254.4
The remainder is 100 after subtracting 2640 from 2740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 10:
660 can be fit into 1000 1 times, resulting in a remainder of 340.
Use 1 as the next digit of our solution. 
Result so far: 30254.41
If we subtract 660 from 1000, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 11:
660 can be fit into 3400 5 times, resulting in a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 30254.415
If we take 3300 away from 3400, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 12:
1000 divided by 660 is 1 with a remainder of 340.
Write down 1 as next digit of the result. 
Result so far: 30254.4151
If we take 660 away from 1000, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 13:
660 goes into 3400 5 times with a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 30254.41515
Deduct 3300 from 3400 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 14:
660 can be fit into 1000 1 times, resulting in a remainder of 340.
Put 1 as the next digit of the answer. 
Result so far: 30254.415151
Subtracting 660 from 1000 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 15:
3400 divided by 660 is 5 with a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 30254.4151515
Subtracting 3300 from 3400 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 16:
When dividing 1000 by 660, we get 1 with a remainder of 340.
The number 1 becomes the next digit in our result. 
Result so far: 30254.41515151
Subtract 660 from 1000 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

The final outcome is 30254.41515151, with a leftover of 3.4e-07.
