We're dividing 512955 by 72 
We want to figure out the number of times 512955 can be divided by 72.

Let's proceed to step 1:
5 divided by 72 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 72

Advancing to step 2:
51 divided by 72 is 0 with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Append the next digit (2) from the dividend to 51 and continue with: 512 / 72

Let's proceed to step 3:
If we divide 512 by 72, we get 7 and a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 504 from 512 to get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 72

Step 4:
If we divide 89 by 72, we get 1 and a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
If we take 72 away from 89, we end up with 17.
Bring next digit (5) of the dividend behind the 17 and repeat the process: 175 / 72

Going ahead to step 5:
72 can be fit into 175 2 times, resulting in a remainder of 31.
Put 2 as the next digit of the answer. 
Result so far: 712.0
If we take 144 away from 175, we end up with 31.
Grab the next digit (5) from the dividend, add it to 31, then carry on: 315 / 72

Moving on to step 6:
When dividing 315 by 72, we get 4 with a remainder of 27.
Write down 4 as next digit of the result. 
Result so far: 7124.0
The remainder is 27 after subtracting 288 from 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 7:
72 can be fit into 270 3 times, resulting in a remainder of 54.
Put 3 as the next digit of the answer. 
Result so far: 7124.3
If we subtract 216 from 270, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 8:
72 goes into 540 7 times with a remainder of 36.
Write down 7 as next digit of the result. 
Result so far: 7124.37
The remainder is 36 after subtracting 504 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
72 can be fit into 360 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 7124.375
If we subtract 360 from 360, 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.

On to step 10:
0 divided by 72 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7124.375
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.

Moving on to step 11:
If we divide 0 by 72, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 7124.375
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.

The final result is 7124.375 with a remainder of 0.0.
