We look at the division of 72855358 by 512 
We want to figure out the number of times 72855358 can be divided by 512.

On to step 1:
512 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 512

Going ahead to step 2:
72 divided by 512 is 0 with a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Fetch the next digit (8) from the dividend, attach it to 72 and continue: 728 / 512

On to step 3:
512 goes into 728 1 times with a remainder of 216.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 512 away from 728, we end up with 216.
Fetch the next digit (5) from the dividend, attach it to 216 and continue: 2165 / 512

Moving on to step 4:
512 goes into 2165 4 times with a remainder of 117.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 2048 from 2165, we get 117.
Include the next digit (5) from the dividend after 117, then repeat: 1175 / 512

Going ahead to step 5:
512 can be fit into 1175 2 times, resulting in a remainder of 151.
The number 2 becomes the next digit in our result. 
Result so far: 142.0
The remainder is 151 after subtracting 1024 from 1175.
Fetch the next digit (3) from the dividend, attach it to 151 and continue: 1513 / 512

Advancing to step 6:
512 goes into 1513 2 times with a remainder of 489.
The next digit of our result is 2. 
Result so far: 1422.0
Subtracting 1024 from 1513 leaves us with 489.
Append the next digit (5) from the dividend to 489 and continue with: 4895 / 512

Moving on to step 7:
512 goes into 4895 9 times with a remainder of 287.
Record the quotient 9 as the next digit in the result. 
Result so far: 14229.0
The remainder is 287 after subtracting 4608 from 4895.
Bring next digit (8) of the dividend behind the 287 and repeat the process: 2878 / 512

Going ahead to step 8:
When dividing 2878 by 512, we get 5 with a remainder of 318.
Write down 5 as next digit of the result. 
Result so far: 142295.0
Deduct 2560 from 2878 and we're left with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Advancing to step 9:
512 goes into 3180 6 times with a remainder of 108.
The next digit of our result is 6. 
Result so far: 142295.6
If we take 3072 away from 3180, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 10:
1080 divided by 512 is 2 with a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 142295.62
Subtracting 1024 from 1080 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 11:
If we divide 560 by 512, we get 1 and a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 142295.621
The remainder is 48 after subtracting 512 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 12:
If we divide 480 by 512, we get 0 and a remainder of 480.
The number 0 becomes the next digit in our result. 
Result so far: 142295.621
If we take 0 away from 480, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 13:
When dividing 4800 by 512, we get 9 with a remainder of 192.
Use 9 as the next digit of our solution. 
Result so far: 142295.62109
If we subtract 4608 from 4800, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 14:
When dividing 1920 by 512, we get 3 with a remainder of 384.
Write down 3 as next digit of the result. 
Result so far: 142295.621093
The remainder is 384 after subtracting 1536 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Moving on to step 15:
512 goes into 3840 7 times with a remainder of 256.
The number 7 becomes the next digit in our result. 
Result so far: 142295.6210937
The remainder is 256 after subtracting 3584 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 16:
2560 divided by 512 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 142295.62109375
If we take 2560 away from 2560, we end up 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.

After the division, we end up with 142295.62109375 and a remainder of 0.0.
