781978 divided by 72 
We're looking to find how many times 72 goes into 781978.

On to step 1:
72 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 72

Going ahead to step 2:
When dividing 78 by 72, we get 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 72 from 78, we get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 72

Step 3:
If we divide 61 by 72, we get 0 and a remainder of 61.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 61, we get 61.
Take the next digit (9) from the dividend and append it to 61, then repeat: 619 / 72

Moving on to step 4:
72 goes into 619 8 times with a remainder of 43.
Record the quotient 8 as the next digit in the result. 
Result so far: 108.0
If we subtract 576 from 619, we get 43.
Append the next digit (7) from the dividend to 43 and continue with: 437 / 72

Moving on to step 5:
72 goes into 437 6 times with a remainder of 5.
The next digit of our result is 6. 
Result so far: 1086.0
Deduct 432 from 437 and we're left with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 72

Let's proceed to step 6:
58 divided by 72 is 0 with a remainder of 58.
Put 0 as the next digit of the answer. 
Result so far: 10860.0
Subtract 0 from 58 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 7:
580 divided by 72 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 10860.8
The remainder is 4 after subtracting 576 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
40 divided by 72 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 10860.8
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
72 goes into 400 5 times with a remainder of 40.
The next digit of our result is 5. 
Result so far: 10860.805
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
400 divided by 72 is 5 with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 10860.8055
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 10860.8055, with a leftover of 0.0004.
