25159126 ÷ 716 
We want to figure out the number of times 25159126 can be divided by 716.

Step 1:
716 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 716

On to step 2:
The number 716 fits into 25 0 times, leaving a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Include the next digit (1) from the dividend after 25, then repeat: 251 / 716

Step 3:
716 goes into 251 0 times with a remainder of 251.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 251 after subtracting 0 from 251.
Grab the next digit (5) from the dividend, add it to 251, then carry on: 2515 / 716

Advancing to step 4:
When dividing 2515 by 716, we get 3 with a remainder of 367.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 2148 from 2515 to get 367.
Grab the next digit (9) from the dividend, add it to 367, then carry on: 3679 / 716

Going ahead to step 5:
716 goes into 3679 5 times with a remainder of 99.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Deduct 3580 from 3679 and we're left with 99.
Grab the next digit (1) from the dividend, add it to 99, then carry on: 991 / 716

Going ahead to step 6:
If we divide 991 by 716, we get 1 and a remainder of 275.
Use 1 as the next digit of our solution. 
Result so far: 351.0
Deduct 716 from 991 and we're left with 275.
Fetch the next digit (2) from the dividend, attach it to 275 and continue: 2752 / 716

Advancing to step 7:
The number 716 fits into 2752 3 times, leaving a remainder of 604.
The number 3 becomes the next digit in our result. 
Result so far: 3513.0
Subtract 2148 from 2752 to get 604.
Take the next digit (6) from the dividend and append it to 604, then repeat: 6046 / 716

Step 8:
716 goes into 6046 8 times with a remainder of 318.
Use 8 as the next digit of our solution. 
Result so far: 35138.0
Subtract 5728 from 6046 to get 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Let's proceed to step 9:
716 goes into 3180 4 times with a remainder of 316.
Use 4 as the next digit of our solution. 
Result so far: 35138.4
Subtracting 2864 from 3180 leaves us with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Let's proceed to step 10:
When dividing 3160 by 716, we get 4 with a remainder of 296.
The number 4 becomes the next digit in our result. 
Result so far: 35138.44
The remainder is 296 after subtracting 2864 from 3160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

The final result is 35138.44 with a remainder of 0.296.
