72879378 ÷ 4 
Our goal is to divide 72879378 by 4.

Step 1:
7 divided by 4 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 4 from 7 to get 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 4

Step 2:
When dividing 32 by 4, we get 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Deduct 32 from 32 and we're left with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 4

Step 3:
The number 4 fits into 8 2 times, leaving a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 182.0
Subtracting 8 from 8 leaves us with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 4

On to step 4:
7 divided by 4 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1821.0
Subtracting 4 from 7 leaves us with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 4

Advancing to step 5:
The number 4 fits into 39 9 times, leaving a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 18219.0
If we take 36 away from 39, we end up with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 4

On to step 6:
33 divided by 4 is 8 with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 182198.0
If we subtract 32 from 33, we get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 4

Moving on to step 7:
17 divided by 4 is 4 with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 1821984.0
Subtracting 16 from 17 leaves us with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 4

Step 8:
4 can be fit into 18 4 times, resulting in a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 18219844.0
If we take 16 away from 18, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
The number 4 fits into 20 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 18219844.5
Subtracting 20 from 20 leaves us 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.

Going ahead to step 10:
0 divided by 4 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 18219844.5
Subtracting 0 from 0 leaves us 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.

Moving on to step 11:
When dividing 0 by 4, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 18219844.5
Deduct 0 from 0 and we're left 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.

In conclusion, the division gives 18219844.5 with a balance of 0.0.
