We look at the division of 512278 by 68 
We want to figure out the number of times 512278 can be divided by 68.

Going ahead to step 1:
If we divide 5 by 68, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 68

Step 2:
The number 68 fits into 51 0 times, leaving a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Include the next digit (2) from the dividend after 51, then repeat: 512 / 68

Going ahead to step 3:
If we divide 512 by 68, we get 7 and a remainder of 36.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 476 from 512 leaves us with 36.
Take the next digit (2) from the dividend and append it to 36, then repeat: 362 / 68

Step 4:
The number 68 fits into 362 5 times, leaving a remainder of 22.
Use 5 as the next digit of our solution. 
Result so far: 75.0
Subtract 340 from 362 to get 22.
Append the next digit (7) from the dividend to 22 and continue with: 227 / 68

Let's proceed to step 5:
227 divided by 68 is 3 with a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 753.0
Subtract 204 from 227 to get 23.
Grab the next digit (8) from the dividend, add it to 23, then carry on: 238 / 68

Let's proceed to step 6:
68 goes into 238 3 times with a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 7533.0
Subtract 204 from 238 to 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.

Moving on to step 7:
68 goes into 340 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 7533.5
Subtracting 340 from 340 leaves us 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.

Step 8:
0 divided by 68 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 7533.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
0 divided by 68 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7533.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 7533.5 with a remaining 0.0.
