We look at the division of 259635 by 54 
We're looking to find how many times 54 goes into 259635.

Let's proceed to step 1:
The number 54 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 54

Advancing to step 2:
25 divided by 54 is 0 with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Grab the next digit (9) from the dividend, add it to 25, then carry on: 259 / 54

Step 3:
54 can be fit into 259 4 times, resulting in a remainder of 43.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 216 from 259 to get 43.
Fetch the next digit (6) from the dividend, attach it to 43 and continue: 436 / 54

Step 4:
If we divide 436 by 54, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 48.0
Subtract 432 from 436 to get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 54

Step 5:
When dividing 43 by 54, we get 0 with a remainder of 43.
The next digit of our result is 0. 
Result so far: 480.0
Subtract 0 from 43 to get 43.
Take the next digit (5) from the dividend and append it to 43, then repeat: 435 / 54

On to step 6:
The number 54 fits into 435 8 times, leaving a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 4808.0
The remainder is 3 after subtracting 432 from 435.
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:
54 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 4808.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
When dividing 300 by 54, we get 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 4808.05
If we take 270 away from 300, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
54 can be fit into 300 5 times, resulting in a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 4808.055
The remainder is 30 after subtracting 270 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 4808.055 with a remainder of 0.003.
