We look at the division of 543981 by 13 
We want to figure out the number of times 543981 can be divided by 13.

Let's proceed to step 1:
When dividing 5 by 13, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 13

Let's proceed to step 2:
When dividing 54 by 13, we get 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 52 away from 54, we end up with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 13

Let's proceed to step 3:
When dividing 23 by 13, we get 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 41.0
Subtracting 13 from 23 leaves us with 10.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 13

Let's proceed to step 4:
The number 13 fits into 109 8 times, leaving a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 418.0
If we subtract 104 from 109, we get 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 13

Going ahead to step 5:
If we divide 58 by 13, we get 4 and a remainder of 6.
The next digit of our result is 4. 
Result so far: 4184.0
If we take 52 away from 58, we end up with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 13

Advancing to step 6:
13 can be fit into 61 4 times, resulting in a remainder of 9.
The next digit of our result is 4. 
Result so far: 41844.0
If we take 52 away from 61, 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 7:
13 can be fit into 90 6 times, resulting in a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 41844.6
If we subtract 78 from 90, we get 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 8:
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: 41844.69
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 9:
13 can be fit into 30 2 times, resulting in a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 41844.692
If we take 26 away from 30, we end up 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.

On to step 10:
13 can be fit into 40 3 times, resulting in a remainder of 1.
The next digit of our result is 3. 
Result so far: 41844.6923
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 11:
10 divided by 13 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 41844.6923
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.

Step 12:
The number 13 fits into 100 7 times, leaving a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 41844.692307
Deduct 91 from 100 and we're left 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.

Going ahead to step 13:
If we divide 90 by 13, we get 6 and a remainder of 12.
The next digit of our result is 6. 
Result so far: 41844.6923076
If we subtract 78 from 90, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 14:
If we divide 120 by 13, we get 9 and a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 41844.69230769
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.

The quotient of the division is 41844.69230769, and the remainder is 3e-09.
