783945 ÷ 72 
We want to figure out the number of times 783945 can be divided by 72.

Moving on to step 1:
72 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 72

On to step 2:
The number 72 fits into 78 1 times, leaving a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 72 from 78 leaves us with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 72

Let's proceed to step 3:
63 divided by 72 is 0 with a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 63 leaves us with 63.
Fetch the next digit (9) from the dividend, attach it to 63 and continue: 639 / 72

On to step 4:
72 can be fit into 639 8 times, resulting in a remainder of 63.
The next digit of our result is 8. 
Result so far: 108.0
Subtract 576 from 639 to get 63.
Append the next digit (4) from the dividend to 63 and continue with: 634 / 72

On to step 5:
72 goes into 634 8 times with a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 1088.0
If we subtract 576 from 634, we get 58.
Append the next digit (5) from the dividend to 58 and continue with: 585 / 72

Going ahead to step 6:
The number 72 fits into 585 8 times, leaving a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 10888.0
If we subtract 576 from 585, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
90 divided by 72 is 1 with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 10888.1
Deduct 72 from 90 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
180 divided by 72 is 2 with a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 10888.12
Subtracting 144 from 180 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 9:
72 goes into 360 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 10888.125
Subtracting 360 from 360 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 10:
72 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10888.125
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.

Let's proceed to step 11:
If we divide 0 by 72, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10888.125
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.

After the division, we end up with 10888.125 and a remainder of 0.0.
