561016 divided by 72 
We want to figure out the number of times 561016 can be divided by 72.

Step 1:
When dividing 5 by 72, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 72

Advancing to step 2:
If we divide 56 by 72, we get 0 and a remainder of 56.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 56, we end up with 56.
Include the next digit (1) from the dividend after 56, then repeat: 561 / 72

Advancing to step 3:
561 divided by 72 is 7 with a remainder of 57.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 504 from 561 and we're left with 57.
Include the next digit (0) from the dividend after 57, then repeat: 570 / 72

Step 4:
If we divide 570 by 72, we get 7 and a remainder of 66.
The next digit of our result is 7. 
Result so far: 77.0
If we take 504 away from 570, we end up with 66.
Bring next digit (1) of the dividend behind the 66 and repeat the process: 661 / 72

Let's proceed to step 5:
661 divided by 72 is 9 with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 779.0
Deduct 648 from 661 and we're left with 13.
Append the next digit (6) from the dividend to 13 and continue with: 136 / 72

Advancing to step 6:
If we divide 136 by 72, we get 1 and a remainder of 64.
Put 1 as the next digit of the answer. 
Result so far: 7791.0
If we subtract 72 from 136, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 7:
640 divided by 72 is 8 with a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 7791.8
If we take 576 away from 640, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 8:
When dividing 640 by 72, we get 8 with a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 7791.88
Subtract 576 from 640 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 7791.88 and a remainder of 0.064.
