54134509 ÷ 255 
We want to figure out the number of times 54134509 can be divided by 255.

Let's proceed to step 1:
255 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 255

Advancing to step 2:
When dividing 54 by 255, we get 0 with a remainder of 54.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 54 after subtracting 0 from 54.
Append the next digit (1) from the dividend to 54 and continue with: 541 / 255

On to step 3:
When dividing 541 by 255, we get 2 with a remainder of 31.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 31 after subtracting 510 from 541.
Grab the next digit (3) from the dividend, add it to 31, then carry on: 313 / 255

Advancing to step 4:
255 goes into 313 1 times with a remainder of 58.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we subtract 255 from 313, we get 58.
Grab the next digit (4) from the dividend, add it to 58, then carry on: 584 / 255

Going ahead to step 5:
When dividing 584 by 255, we get 2 with a remainder of 74.
Put 2 as the next digit of the answer. 
Result so far: 212.0
Subtract 510 from 584 to get 74.
Bring next digit (5) of the dividend behind the 74 and repeat the process: 745 / 255

Moving on to step 6:
255 goes into 745 2 times with a remainder of 235.
Use 2 as the next digit of our solution. 
Result so far: 2122.0
If we subtract 510 from 745, we get 235.
Append the next digit (0) from the dividend to 235 and continue with: 2350 / 255

Advancing to step 7:
If we divide 2350 by 255, we get 9 and a remainder of 55.
The next digit of our result is 9. 
Result so far: 21229.0
Subtracting 2295 from 2350 leaves us with 55.
Bring next digit (9) of the dividend behind the 55 and repeat the process: 559 / 255

Advancing to step 8:
The number 255 fits into 559 2 times, leaving a remainder of 49.
Put 2 as the next digit of the answer. 
Result so far: 212292.0
If we subtract 510 from 559, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 9:
255 goes into 490 1 times with a remainder of 235.
The number 1 becomes the next digit in our result. 
Result so far: 212292.1
Deduct 255 from 490 and we're left with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Advancing to step 10:
When dividing 2350 by 255, we get 9 with a remainder of 55.
The number 9 becomes the next digit in our result. 
Result so far: 212292.19
Deduct 2295 from 2350 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 11:
550 divided by 255 is 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 212292.192
The remainder is 40 after subtracting 510 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
255 can be fit into 400 1 times, resulting in a remainder of 145.
The number 1 becomes the next digit in our result. 
Result so far: 212292.1921
Subtracting 255 from 400 leaves us with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Step 13:
When dividing 1450 by 255, we get 5 with a remainder of 175.
The next digit of our result is 5. 
Result so far: 212292.19215
The remainder is 175 after subtracting 1275 from 1450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Step 14:
The number 255 fits into 1750 6 times, leaving a remainder of 220.
The number 6 becomes the next digit in our result. 
Result so far: 212292.192156
If we take 1530 away from 1750, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 15:
The number 255 fits into 2200 8 times, leaving a remainder of 160.
The number 8 becomes the next digit in our result. 
Result so far: 212292.1921568
If we take 2040 away from 2200, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 16:
The number 255 fits into 1600 6 times, leaving a remainder of 70.
Use 6 as the next digit of our solution. 
Result so far: 212292.19215686
The remainder is 70 after subtracting 1530 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 212292.19215686 with a remainder of 7e-08.
