Let's divide 77439313 by 25
We're looking to find how many times 25 goes into 77439313.

Going ahead to step 1:
25 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 25

Step 2:
25 can be fit into 77 3 times, resulting in a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 75 from 77 leaves us with 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 25

On to step 3:
The number 25 fits into 24 0 times, leaving a remainder of 24.
Put 0 as the next digit of the answer. 
Result so far: 30.0
If we subtract 0 from 24, we get 24.
Append the next digit (3) from the dividend to 24 and continue with: 243 / 25

Moving on to step 4:
When dividing 243 by 25, we get 9 with a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 309.0
If we subtract 225 from 243, we get 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 25

Going ahead to step 5:
189 divided by 25 is 7 with a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 3097.0
Deduct 175 from 189 and we're left with 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 25

Going ahead to step 6:
25 goes into 143 5 times with a remainder of 18.
The next digit of our result is 5. 
Result so far: 30975.0
If we subtract 125 from 143, we get 18.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 25

Advancing to step 7:
If we divide 181 by 25, we get 7 and a remainder of 6.
The next digit of our result is 7. 
Result so far: 309757.0
Subtract 175 from 181 to get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 25

Step 8:
If we divide 63 by 25, we get 2 and a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 3097572.0
If we take 50 away from 63, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 9:
130 divided by 25 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 3097572.5
Subtracting 125 from 130 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 10:
50 divided by 25 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 3097572.52
If we subtract 50 from 50, 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.

Advancing to step 11:
25 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3097572.52
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.

Moving on to step 12:
0 divided by 25 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3097572.52
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.

In conclusion, the division gives 3097572.52 with a balance of 0.0.
