We look at the division of 54387 by 13 
We want to figure out the number of times 54387 can be divided by 13.

Going ahead to step 1:
13 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 13

Moving on to step 2:
13 can be fit into 54 4 times, resulting in a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 52 from 54 and we're left with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 13

Let's proceed to step 3:
If we divide 23 by 13, we get 1 and a remainder of 10.
The next digit of our result is 1. 
Result so far: 41.0
The remainder is 10 after subtracting 13 from 23.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 13

On to step 4:
13 can be fit into 108 8 times, resulting in a remainder of 4.
The next digit of our result is 8. 
Result so far: 418.0
Subtract 104 from 108 to get 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 13

Step 5:
47 divided by 13 is 3 with a remainder of 8.
The next digit of our result is 3. 
Result so far: 4183.0
Deduct 39 from 47 and we're left 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.

Moving on to step 6:
80 divided by 13 is 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 4183.6
If we take 78 away from 80, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
The number 13 fits into 20 1 times, leaving a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 4183.61
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.

Let's proceed to step 8:
When dividing 70 by 13, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 4183.615
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.

On to step 9:
13 can be fit into 50 3 times, resulting in a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 4183.6153
If we subtract 39 from 50, we 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.

Going ahead to step 10:
110 divided by 13 is 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 4183.61538
If we take 104 away from 110, we end up 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.

On to step 11:
60 divided by 13 is 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 4183.615384
The remainder is 8 after subtracting 52 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
The number 13 fits into 80 6 times, leaving a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 4183.6153846
If we take 78 away from 80, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 13:
The number 13 fits into 20 1 times, leaving a remainder of 7.
The next digit of our result is 1. 
Result so far: 4183.61538461
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.

After the division, we end up with 4183.61538461 and a remainder of 7e-09.
