We look at the division of 879939 by 72 
We want to divide 879939 by 72.

Let's proceed to step 1:
If we divide 8 by 72, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 72

Let's proceed to step 2:
72 goes into 87 1 times with a remainder of 15.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 72 from 87 and we're left with 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 72

Going ahead to step 3:
If we divide 159 by 72, we get 2 and a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 144 from 159 leaves us with 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 72

Moving on to step 4:
72 can be fit into 159 2 times, resulting in a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 122.0
Subtracting 144 from 159 leaves us with 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 72

Going ahead to step 5:
153 divided by 72 is 2 with a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 1222.0
If we take 144 away from 153, we end up with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 72

Moving on to step 6:
When dividing 99 by 72, we get 1 with a remainder of 27.
The next digit of our result is 1. 
Result so far: 12221.0
Subtracting 72 from 99 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 7:
72 goes into 270 3 times with a remainder of 54.
Record the quotient 3 as the next digit in the result. 
Result so far: 12221.3
Subtract 216 from 270 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 8:
72 can be fit into 540 7 times, resulting in a remainder of 36.
The next digit of our result is 7. 
Result so far: 12221.37
Subtract 504 from 540 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
72 can be fit into 360 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 12221.375
Subtract 360 from 360 to 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 10:
The number 72 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 12221.375
If we take 0 away from 0, we end up 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 11:
If we divide 0 by 72, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12221.375
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.

The final result is 12221.375 with a remainder of 0.0.
