We're dividing 65139513 by 268 
We want to figure out the number of times 65139513 can be divided by 268.

Going ahead to step 1:
268 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 268

Going ahead to step 2:
268 goes into 65 0 times with a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 65 leaves us with 65.
Bring next digit (1) of the dividend behind the 65 and repeat the process: 651 / 268

On to step 3:
268 goes into 651 2 times with a remainder of 115.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 536 away from 651, we end up with 115.
Take the next digit (3) from the dividend and append it to 115, then repeat: 1153 / 268

On to step 4:
When dividing 1153 by 268, we get 4 with a remainder of 81.
The next digit of our result is 4. 
Result so far: 24.0
The remainder is 81 after subtracting 1072 from 1153.
Bring next digit (9) of the dividend behind the 81 and repeat the process: 819 / 268

On to step 5:
The number 268 fits into 819 3 times, leaving a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 243.0
If we take 804 away from 819, we end up with 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 268

Advancing to step 6:
When dividing 155 by 268, we get 0 with a remainder of 155.
Put 0 as the next digit of the answer. 
Result so far: 2430.0
If we subtract 0 from 155, we get 155.
Fetch the next digit (1) from the dividend, attach it to 155 and continue: 1551 / 268

Step 7:
1551 divided by 268 is 5 with a remainder of 211.
Record the quotient 5 as the next digit in the result. 
Result so far: 24305.0
Deduct 1340 from 1551 and we're left with 211.
Bring next digit (3) of the dividend behind the 211 and repeat the process: 2113 / 268

On to step 8:
The number 268 fits into 2113 7 times, leaving a remainder of 237.
The number 7 becomes the next digit in our result. 
Result so far: 243057.0
If we subtract 1876 from 2113, we get 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Going ahead to step 9:
2370 divided by 268 is 8 with a remainder of 226.
Put 8 as the next digit of the answer. 
Result so far: 243057.8
If we take 2144 away from 2370, we end up with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Going ahead to step 10:
2260 divided by 268 is 8 with a remainder of 116.
Write down 8 as next digit of the result. 
Result so far: 243057.88
If we subtract 2144 from 2260, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

The quotient of the division is 243057.88, and the remainder is 0.116.
