We look at the division of 78448 by 72 
We're looking to find how many times 72 goes into 78448.

Let's proceed to step 1:
7 divided by 72 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 72

On to step 2:
78 divided by 72 is 1 with a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 72 from 78 and we're left with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 72

Going ahead to step 3:
72 can be fit into 64 0 times, resulting in a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 64 leaves us with 64.
Append the next digit (4) from the dividend to 64 and continue with: 644 / 72

Step 4:
If we divide 644 by 72, we get 8 and a remainder of 68.
Write down 8 as next digit of the result. 
Result so far: 108.0
Subtract 576 from 644 to get 68.
Bring next digit (8) of the dividend behind the 68 and repeat the process: 688 / 72

Going ahead to step 5:
688 divided by 72 is 9 with a remainder of 40.
Put 9 as the next digit of the answer. 
Result so far: 1089.0
The remainder is 40 after subtracting 648 from 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 6:
72 can be fit into 400 5 times, resulting in a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 1089.5
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.

Advancing to step 7:
When dividing 400 by 72, we get 5 with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 1089.55
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 1089.55 and a remainder of 0.04.
