We're dividing 163491 by 13 
We're looking to find how many times 13 goes into 163491.

Advancing to step 1:
The number 13 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 13

Step 2:
16 divided by 13 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 13 from 16, we get 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 13

Going ahead to step 3:
13 can be fit into 33 2 times, resulting in a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 26 away from 33, we end up with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 13

On to step 4:
If we divide 74 by 13, we get 5 and a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
Subtracting 65 from 74 leaves us with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 13

Advancing to step 5:
13 goes into 99 7 times with a remainder of 8.
The next digit of our result is 7. 
Result so far: 1257.0
If we subtract 91 from 99, we get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 13

Going ahead to step 6:
13 can be fit into 81 6 times, resulting in a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 12576.0
If we take 78 away from 81, we end up 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.

Going ahead to step 7:
The number 13 fits into 30 2 times, leaving a remainder of 4.
The next digit of our result is 2. 
Result so far: 12576.2
Subtract 26 from 30 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
When dividing 40 by 13, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 12576.23
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.

Moving on to step 9:
If we divide 10 by 13, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 12576.23
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
13 goes into 100 7 times with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 12576.2307
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.

Advancing to step 11:
If we divide 90 by 13, we get 6 and a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 12576.23076
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.

Step 12:
When dividing 120 by 13, we get 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 12576.230769
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.

On to step 13:
The number 13 fits into 30 2 times, leaving a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 12576.2307692
If we subtract 26 from 30, we get 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 14:
13 can be fit into 40 3 times, resulting in a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 12576.23076923
If we subtract 39 from 40, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 12576.23076923 with a balance of 1e-09.
