Let's divide 51575824 by 240
We want to divide 51575824 by 240.

Step 1:
The number 240 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 240

Advancing to step 2:
51 divided by 240 is 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Take the next digit (5) from the dividend and append it to 51, then repeat: 515 / 240

Step 3:
240 goes into 515 2 times with a remainder of 35.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 480 from 515 to get 35.
Take the next digit (7) from the dividend and append it to 35, then repeat: 357 / 240

On to step 4:
357 divided by 240 is 1 with a remainder of 117.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we take 240 away from 357, we end up with 117.
Fetch the next digit (5) from the dividend, attach it to 117 and continue: 1175 / 240

Moving on to step 5:
240 goes into 1175 4 times with a remainder of 215.
The next digit of our result is 4. 
Result so far: 214.0
The remainder is 215 after subtracting 960 from 1175.
Include the next digit (8) from the dividend after 215, then repeat: 2158 / 240

On to step 6:
The number 240 fits into 2158 8 times, leaving a remainder of 238.
The number 8 becomes the next digit in our result. 
Result so far: 2148.0
If we subtract 1920 from 2158, we get 238.
Append the next digit (2) from the dividend to 238 and continue with: 2382 / 240

Going ahead to step 7:
If we divide 2382 by 240, we get 9 and a remainder of 222.
The number 9 becomes the next digit in our result. 
Result so far: 21489.0
The remainder is 222 after subtracting 2160 from 2382.
Bring next digit (4) of the dividend behind the 222 and repeat the process: 2224 / 240

On to step 8:
240 can be fit into 2224 9 times, resulting in a remainder of 64.
Write down 9 as next digit of the result. 
Result so far: 214899.0
Subtracting 2160 from 2224 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 9:
When dividing 640 by 240, we get 2 with a remainder of 160.
Use 2 as the next digit of our solution. 
Result so far: 214899.2
If we subtract 480 from 640, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 10:
240 can be fit into 1600 6 times, resulting in a remainder of 160.
Use 6 as the next digit of our solution. 
Result so far: 214899.26
If we take 1440 away from 1600, 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.

Advancing to step 11:
240 can be fit into 1600 6 times, resulting in a remainder of 160.
The number 6 becomes the next digit in our result. 
Result so far: 214899.266
If we subtract 1440 from 1600, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

After the division, we end up with 214899.266 and a remainder of 0.016.
