18513136 divided by 13 
We want to figure out the number of times 18513136 can be divided by 13.

Going ahead to step 1:
When dividing 1 by 13, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 13

Step 2:
13 goes into 18 1 times with a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
If we take 13 away from 18, we end up with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 13

On to step 3:
When dividing 55 by 13, we get 4 with a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 52 from 55 and we're left with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 13

Going ahead to step 4:
When dividing 31 by 13, we get 2 with a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 142.0
Deduct 26 from 31 and we're left with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 13

Let's proceed to step 5:
13 can be fit into 53 4 times, resulting in a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 1424.0
Subtract 52 from 53 to get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 13

Advancing to step 6:
When dividing 11 by 13, we get 0 with a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 14240.0
If we take 0 away from 11, we end up with 11.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 13

On to step 7:
The number 13 fits into 113 8 times, leaving a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 142408.0
If we take 104 away from 113, we end up with 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 13

Going ahead to step 8:
The number 13 fits into 96 7 times, leaving a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 1424087.0
The remainder is 5 after subtracting 91 from 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
When dividing 50 by 13, we get 3 with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 1424087.3
Subtract 39 from 50 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 10:
110 divided by 13 is 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 1424087.38
Subtract 104 from 110 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 11:
If we divide 60 by 13, we get 4 and a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 1424087.384
If we take 52 away from 60, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
80 divided by 13 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 1424087.3846
If we subtract 78 from 80, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 13:
13 goes into 20 1 times with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1424087.38461
If we take 13 away from 20, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 14:
13 goes into 70 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 1424087.384615
Subtracting 65 from 70 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 15:
If we divide 50 by 13, we get 3 and a remainder of 11.
The next digit of our result is 3. 
Result so far: 1424087.3846153
The remainder is 11 after subtracting 39 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 16:
13 can be fit into 110 8 times, resulting in a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 1424087.38461538
Subtracting 104 from 110 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 1424087.38461538 and a remainder of 6e-09.
