Let's divide 163944 by 13
Let's see how many times 13 fits into 163944.

Advancing to step 1:
When dividing 1 by 13, we get 0 with 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.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 13

Let's proceed to step 2:
If we divide 16 by 13, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 13 away from 16, we end up with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 13

Advancing to step 3:
The number 13 fits into 33 2 times, leaving a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 26 from 33 to get 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 13

On to step 4:
If we divide 79 by 13, we get 6 and a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 126.0
The remainder is 1 after subtracting 78 from 79.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 13

Going ahead to step 5:
13 can be fit into 14 1 times, resulting in a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1261.0
Subtract 13 from 14 to get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 13

Step 6:
14 divided by 13 is 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 12611.0
The remainder is 1 after subtracting 13 from 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
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: 12611.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
13 can be fit into 100 7 times, resulting in a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 12611.07
Subtract 91 from 100 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.

Moving on to step 9:
If we divide 90 by 13, we get 6 and a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 12611.076
Deduct 78 from 90 and we're left 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.

On to step 10:
When dividing 120 by 13, we get 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 12611.0769
Deduct 117 from 120 and we're left 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.

Advancing to step 11:
When dividing 30 by 13, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 12611.07692
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.

Moving on to step 12:
If we divide 40 by 13, we get 3 and a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 12611.076923
The remainder is 1 after subtracting 39 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 13:
13 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 12611.076923
Deduct 0 from 10 and we're left 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.

Advancing to step 14:
13 goes into 100 7 times with a remainder of 9.
The next digit of our result is 7. 
Result so far: 12611.07692307
Subtracting 91 from 100 leaves us 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.

In conclusion, the division gives 12611.07692307 with a balance of 9e-09.
