Moving on to step 5:
When dividing 77 by 72, we get 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 811.0
Deduct 72 from 77 and we're left with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 72

Moving on to step 6:
When dividing 50 by 72, we get 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 8110.0
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 7:
72 can be fit into 500 6 times, resulting in a remainder of 68.
The number 6 becomes the next digit in our result. 
Result so far: 8110.6
Deduct 432 from 500 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 8:
680 divided by 72 is 9 with a remainder of 32.
Put 9 as the next digit of the answer. 
Result so far: 8110.69
If we subtract 648 from 680, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 9:
320 divided by 72 is 4 with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 8110.694
Subtract 288 from 320 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
If we divide 320 by 72, we get 4 and a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 8110.6944
Subtract 288 from 320 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 8110.6944 with a remainder of 0.00032.
