We divide 781540 by 72
We're looking to find how many times 72 goes into 781540.

Step 1:
If we divide 7 by 72, we get 0 and 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.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 72

Moving on to step 2:
If we divide 78 by 72, we get 1 and a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 72 from 78, we get 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 72

Moving on to step 3:
72 can be fit into 61 0 times, resulting in a remainder of 61.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 61 to get 61.
Take the next digit (5) from the dividend and append it to 61, then repeat: 615 / 72

Advancing to step 4:
615 divided by 72 is 8 with a remainder of 39.
Put 8 as the next digit of the answer. 
Result so far: 108.0
If we take 576 away from 615, we end up with 39.
Include the next digit (4) from the dividend after 39, then repeat: 394 / 72

Let's proceed to step 5:
394 divided by 72 is 5 with a remainder of 34.
Use 5 as the next digit of our solution. 
Result so far: 1085.0
Deduct 360 from 394 and we're left with 34.
Grab the next digit (0) from the dividend, add it to 34, then carry on: 340 / 72

Moving on to step 6:
72 can be fit into 340 4 times, resulting in a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 10854.0
Subtracting 288 from 340 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 7:
The number 72 fits into 520 7 times, leaving a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 10854.7
If we subtract 504 from 520, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 8:
If we divide 160 by 72, we get 2 and a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 10854.72
If we take 144 away from 160, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
The number 72 fits into 160 2 times, leaving a remainder of 16.
The next digit of our result is 2. 
Result so far: 10854.722
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 10854.722 and a remainder of 0.0016.
