We look at the division of 515450 by 72 
We want to figure out the number of times 515450 can be divided by 72.

Moving on to step 1:
72 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 72

Moving on to step 2:
72 goes into 51 0 times with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Fetch the next digit (5) from the dividend, attach it to 51 and continue: 515 / 72

Step 3:
When dividing 515 by 72, we get 7 with a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 504 from 515 to get 11.
Fetch the next digit (4) from the dividend, attach it to 11 and continue: 114 / 72

Moving on to step 4:
72 goes into 114 1 times with a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
Deduct 72 from 114 and we're left with 42.
Include the next digit (5) from the dividend after 42, then repeat: 425 / 72

Step 5:
When dividing 425 by 72, we get 5 with a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 715.0
Deduct 360 from 425 and we're left with 65.
Include the next digit (0) from the dividend after 65, then repeat: 650 / 72

Let's proceed to step 6:
72 goes into 650 9 times with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 7159.0
The remainder is 2 after subtracting 648 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
When dividing 20 by 72, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 7159.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
The number 72 fits into 200 2 times, leaving a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 7159.02
Subtracting 144 from 200 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 9:
560 divided by 72 is 7 with a remainder of 56.
Put 7 as the next digit of the answer. 
Result so far: 7159.027
The remainder is 56 after subtracting 504 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 10:
If we divide 560 by 72, we get 7 and a remainder of 56.
The next digit of our result is 7. 
Result so far: 7159.0277
Deduct 504 from 560 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The quotient of the division is 7159.0277, and the remainder is 0.00056.
