19131213 ÷ 497 
We want to figure out the number of times 19131213 can be divided by 497.

On to step 1:
When dividing 1 by 497, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 497

Step 2:
497 goes into 19 0 times with a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Take the next digit (1) from the dividend and append it to 19, then repeat: 191 / 497

Going ahead to step 3:
If we divide 191 by 497, we get 0 and a remainder of 191.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 191, we get 191.
Bring next digit (3) of the dividend behind the 191 and repeat the process: 1913 / 497

On to step 4:
1913 divided by 497 is 3 with a remainder of 422.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 1491 away from 1913, we end up with 422.
Append the next digit (1) from the dividend to 422 and continue with: 4221 / 497

Step 5:
497 can be fit into 4221 8 times, resulting in a remainder of 245.
Put 8 as the next digit of the answer. 
Result so far: 38.0
If we take 3976 away from 4221, we end up with 245.
Take the next digit (2) from the dividend and append it to 245, then repeat: 2452 / 497

On to step 6:
2452 divided by 497 is 4 with a remainder of 464.
Put 4 as the next digit of the answer. 
Result so far: 384.0
Deduct 1988 from 2452 and we're left with 464.
Include the next digit (1) from the dividend after 464, then repeat: 4641 / 497

Let's proceed to step 7:
497 can be fit into 4641 9 times, resulting in a remainder of 168.
Write down 9 as next digit of the result. 
Result so far: 3849.0
Subtracting 4473 from 4641 leaves us with 168.
Grab the next digit (3) from the dividend, add it to 168, then carry on: 1683 / 497

Step 8:
1683 divided by 497 is 3 with a remainder of 192.
The next digit of our result is 3. 
Result so far: 38493.0
Subtracting 1491 from 1683 leaves us 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.

On to step 9:
497 goes into 1920 3 times with a remainder of 429.
Use 3 as the next digit of our solution. 
Result so far: 38493.3
Subtract 1491 from 1920 to get 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Let's proceed to step 10:
The number 497 fits into 4290 8 times, leaving a remainder of 314.
Write down 8 as next digit of the result. 
Result so far: 38493.38
Deduct 3976 from 4290 and we're left with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Going ahead to step 11:
3140 divided by 497 is 6 with a remainder of 158.
Put 6 as the next digit of the answer. 
Result so far: 38493.386
If we subtract 2982 from 3140, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Going ahead to step 12:
497 can be fit into 1580 3 times, resulting in a remainder of 89.
Put 3 as the next digit of the answer. 
Result so far: 38493.3863
If we subtract 1491 from 1580, we get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

On to step 13:
If we divide 890 by 497, we get 1 and a remainder of 393.
Put 1 as the next digit of the answer. 
Result so far: 38493.38631
Deduct 497 from 890 and we're left with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Advancing to step 14:
3930 divided by 497 is 7 with a remainder of 451.
Record the quotient 7 as the next digit in the result. 
Result so far: 38493.386317
Deduct 3479 from 3930 and we're left with 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

On to step 15:
If we divide 4510 by 497, we get 9 and a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 38493.3863179
Subtracting 4473 from 4510 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 16:
The number 497 fits into 370 0 times, leaving a remainder of 370.
Write down 0 as next digit of the result. 
Result so far: 38493.3863179
Deduct 0 from 370 and we're left with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

The final result is 38493.3863179 with a remainder of 3.7e-07.
