721149 ÷ 78 
We're looking to find how many times 78 goes into 721149.

Going ahead to step 1:
The number 78 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 78

On to step 2:
The number 78 fits into 72 0 times, leaving a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Grab the next digit (1) from the dividend, add it to 72, then carry on: 721 / 78

Going ahead to step 3:
78 can be fit into 721 9 times, resulting in a remainder of 19.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 702 from 721 to get 19.
Take the next digit (1) from the dividend and append it to 19, then repeat: 191 / 78

Moving on to step 4:
The number 78 fits into 191 2 times, leaving a remainder of 35.
The number 2 becomes the next digit in our result. 
Result so far: 92.0
Subtracting 156 from 191 leaves us with 35.
Fetch the next digit (4) from the dividend, attach it to 35 and continue: 354 / 78

Advancing to step 5:
78 can be fit into 354 4 times, resulting in a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 924.0
If we subtract 312 from 354, we get 42.
Include the next digit (9) from the dividend after 42, then repeat: 429 / 78

Advancing to step 6:
The number 78 fits into 429 5 times, leaving a remainder of 39.
The next digit of our result is 5. 
Result so far: 9245.0
Subtracting 390 from 429 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 7:
390 divided by 78 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 9245.5
Subtract 390 from 390 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.

Going ahead to step 8:
78 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9245.5
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 9:
When dividing 0 by 78, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9245.5
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.

In conclusion, the division gives 9245.5 with a balance of 0.0.
