We're dividing 51808956 by 240 
We want to figure out the number of times 51808956 can be divided by 240.

Let's proceed to step 1:
If we divide 5 by 240, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 240

Moving on to step 2:
51 divided by 240 is 0 with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Take the next digit (8) from the dividend and append it to 51, then repeat: 518 / 240

Advancing to step 3:
518 divided by 240 is 2 with a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 38 after subtracting 480 from 518.
Take the next digit (0) from the dividend and append it to 38, then repeat: 380 / 240

On to step 4:
If we divide 380 by 240, we get 1 and a remainder of 140.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtract 240 from 380 to get 140.
Append the next digit (8) from the dividend to 140 and continue with: 1408 / 240

Let's proceed to step 5:
1408 divided by 240 is 5 with a remainder of 208.
Record the quotient 5 as the next digit in the result. 
Result so far: 215.0
Subtracting 1200 from 1408 leaves us with 208.
Take the next digit (9) from the dividend and append it to 208, then repeat: 2089 / 240

Going ahead to step 6:
2089 divided by 240 is 8 with a remainder of 169.
Record the quotient 8 as the next digit in the result. 
Result so far: 2158.0
Subtracting 1920 from 2089 leaves us with 169.
Take the next digit (5) from the dividend and append it to 169, then repeat: 1695 / 240

Going ahead to step 7:
240 goes into 1695 7 times with a remainder of 15.
The next digit of our result is 7. 
Result so far: 21587.0
Subtracting 1680 from 1695 leaves us with 15.
Include the next digit (6) from the dividend after 15, then repeat: 156 / 240

Let's proceed to step 8:
240 goes into 156 0 times with a remainder of 156.
Use 0 as the next digit of our solution. 
Result so far: 215870.0
If we take 0 away from 156, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 9:
If we divide 1560 by 240, we get 6 and a remainder of 120.
Put 6 as the next digit of the answer. 
Result so far: 215870.6
The remainder is 120 after subtracting 1440 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 10:
240 can be fit into 1200 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 215870.65
If we subtract 1200 from 1200, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
0 divided by 240 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 215870.65
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
240 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 215870.65
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 215870.65 with a remainder of 0.0.
