We divide 19666565 by 502
We want to divide 19666565 by 502.

On to step 1:
502 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 502

Let's proceed to step 2:
When dividing 19 by 502, we get 0 with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Take the next digit (6) from the dividend and append it to 19, then repeat: 196 / 502

On to step 3:
502 can be fit into 196 0 times, resulting in a remainder of 196.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 196, we get 196.
Fetch the next digit (6) from the dividend, attach it to 196 and continue: 1966 / 502

Let's proceed to step 4:
1966 divided by 502 is 3 with a remainder of 460.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 1506 from 1966 to get 460.
Include the next digit (6) from the dividend after 460, then repeat: 4606 / 502

Advancing to step 5:
The number 502 fits into 4606 9 times, leaving a remainder of 88.
Use 9 as the next digit of our solution. 
Result so far: 39.0
Deduct 4518 from 4606 and we're left with 88.
Append the next digit (5) from the dividend to 88 and continue with: 885 / 502

Going ahead to step 6:
The number 502 fits into 885 1 times, leaving a remainder of 383.
Use 1 as the next digit of our solution. 
Result so far: 391.0
The remainder is 383 after subtracting 502 from 885.
Fetch the next digit (6) from the dividend, attach it to 383 and continue: 3836 / 502

Advancing to step 7:
When dividing 3836 by 502, we get 7 with a remainder of 322.
Record the quotient 7 as the next digit in the result. 
Result so far: 3917.0
Deduct 3514 from 3836 and we're left with 322.
Include the next digit (5) from the dividend after 322, then repeat: 3225 / 502

Going ahead to step 8:
If we divide 3225 by 502, we get 6 and a remainder of 213.
The number 6 becomes the next digit in our result. 
Result so far: 39176.0
Subtract 3012 from 3225 to get 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

On to step 9:
The number 502 fits into 2130 4 times, leaving a remainder of 122.
Record the quotient 4 as the next digit in the result. 
Result so far: 39176.4
The remainder is 122 after subtracting 2008 from 2130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Step 10:
When dividing 1220 by 502, we get 2 with a remainder of 216.
Record the quotient 2 as the next digit in the result. 
Result so far: 39176.42
Subtract 1004 from 1220 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 11:
If we divide 2160 by 502, we get 4 and a remainder of 152.
The next digit of our result is 4. 
Result so far: 39176.424
Subtract 2008 from 2160 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 12:
If we divide 1520 by 502, we get 3 and a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 39176.4243
Subtract 1506 from 1520 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 13:
When dividing 140 by 502, we get 0 with a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 39176.4243
If we subtract 0 from 140, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 14:
If we divide 1400 by 502, we get 2 and a remainder of 396.
The number 2 becomes the next digit in our result. 
Result so far: 39176.424302
The remainder is 396 after subtracting 1004 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Let's proceed to step 15:
The number 502 fits into 3960 7 times, leaving a remainder of 446.
Write down 7 as next digit of the result. 
Result so far: 39176.4243027
Subtracting 3514 from 3960 leaves us with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Moving on to step 16:
The number 502 fits into 4460 8 times, leaving a remainder of 444.
The next digit of our result is 8. 
Result so far: 39176.42430278
Subtract 4016 from 4460 to get 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

After the division, we end up with 39176.42430278 and a remainder of 4.44e-07.
