We're dividing 19819185 by 13 
Let's see how many times 13 fits into 19819185.

Let's proceed to step 1:
The number 13 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 13

On to step 2:
13 can be fit into 19 1 times, resulting in a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 13 from 19 and we're left with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 13

Moving on to step 3:
13 can be fit into 68 5 times, resulting in a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtracting 65 from 68 leaves us with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 13

Step 4:
If we divide 31 by 13, we get 2 and a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 152.0
Subtract 26 from 31 to get 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 13

Step 5:
The number 13 fits into 59 4 times, leaving a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 1524.0
If we subtract 52 from 59, we get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 13

Step 6:
The number 13 fits into 71 5 times, leaving a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 15245.0
The remainder is 6 after subtracting 65 from 71.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 13

On to step 7:
When dividing 68 by 13, we get 5 with a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 152455.0
Deduct 65 from 68 and we're left with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 13

Advancing to step 8:
35 divided by 13 is 2 with a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 1524552.0
Subtract 26 from 35 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
When dividing 90 by 13, we get 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 1524552.6
If we take 78 away from 90, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
The number 13 fits into 120 9 times, leaving a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 1524552.69
Subtract 117 from 120 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 11:
13 can be fit into 30 2 times, resulting in a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 1524552.692
Subtracting 26 from 30 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 12:
If we divide 40 by 13, we get 3 and a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 1524552.6923
Deduct 39 from 40 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 13:
13 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 1524552.6923
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
13 can be fit into 100 7 times, resulting in a remainder of 9.
The next digit of our result is 7. 
Result so far: 1524552.692307
If we take 91 away from 100, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 15:
13 goes into 90 6 times with a remainder of 12.
The next digit of our result is 6. 
Result so far: 1524552.6923076
Subtracting 78 from 90 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 16:
13 can be fit into 120 9 times, resulting in a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 1524552.69230769
Subtracting 117 from 120 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

After the division, we end up with 1524552.69230769 and a remainder of 3e-09.
