259171 ÷ 54 
We're looking to find how many times 54 goes into 259171.

On to step 1:
If we divide 2 by 54, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 54

Going ahead to step 2:
54 goes into 25 0 times with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Grab the next digit (9) from the dividend, add it to 25, then carry on: 259 / 54

Step 3:
If we divide 259 by 54, we get 4 and a remainder of 43.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 216 from 259, we get 43.
Fetch the next digit (1) from the dividend, attach it to 43 and continue: 431 / 54

On to step 4:
54 can be fit into 431 7 times, resulting in a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
The remainder is 53 after subtracting 378 from 431.
Bring next digit (7) of the dividend behind the 53 and repeat the process: 537 / 54

On to step 5:
The number 54 fits into 537 9 times, leaving a remainder of 51.
Write down 9 as next digit of the result. 
Result so far: 479.0
If we subtract 486 from 537, we get 51.
Append the next digit (1) from the dividend to 51 and continue with: 511 / 54

Step 6:
511 divided by 54 is 9 with a remainder of 25.
Write down 9 as next digit of the result. 
Result so far: 4799.0
If we take 486 away from 511, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 7:
When dividing 250 by 54, we get 4 with a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 4799.4
The remainder is 34 after subtracting 216 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 8:
When dividing 340 by 54, we get 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 4799.46
If we take 324 away from 340, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
When dividing 160 by 54, we get 2 with a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 4799.462
Subtracting 108 from 160 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 10:
When dividing 520 by 54, we get 9 with a remainder of 34.
The number 9 becomes the next digit in our result. 
Result so far: 4799.4629
The remainder is 34 after subtracting 486 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 11:
When dividing 340 by 54, we get 6 with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 4799.46296
The remainder is 16 after subtracting 324 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 12:
When dividing 160 by 54, we get 2 with a remainder of 52.
The next digit of our result is 2. 
Result so far: 4799.462962
The remainder is 52 after subtracting 108 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 13:
The number 54 fits into 520 9 times, leaving a remainder of 34.
Record the quotient 9 as the next digit in the result. 
Result so far: 4799.4629629
If we subtract 486 from 520, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 14:
54 goes into 340 6 times with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 4799.46296296
Deduct 324 from 340 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 4799.46296296 and a remainder of 1.6e-08.
