Let's divide 25990877 by 79
We want to divide 25990877 by 79.

Advancing to step 1:
The number 79 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 79

On to step 2:
If we divide 25 by 79, we get 0 and a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Take the next digit (9) from the dividend and append it to 25, then repeat: 259 / 79

Let's proceed to step 3:
If we divide 259 by 79, we get 3 and a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 237 from 259, we get 22.
Fetch the next digit (9) from the dividend, attach it to 22 and continue: 229 / 79

Moving on to step 4:
229 divided by 79 is 2 with a remainder of 71.
The next digit of our result is 2. 
Result so far: 32.0
If we take 158 away from 229, we end up with 71.
Take the next digit (0) from the dividend and append it to 71, then repeat: 710 / 79

On to step 5:
79 goes into 710 8 times with a remainder of 78.
Write down 8 as next digit of the result. 
Result so far: 328.0
Subtracting 632 from 710 leaves us with 78.
Include the next digit (8) from the dividend after 78, then repeat: 788 / 79

Step 6:
79 can be fit into 788 9 times, resulting in a remainder of 77.
The number 9 becomes the next digit in our result. 
Result so far: 3289.0
If we subtract 711 from 788, we get 77.
Bring next digit (7) of the dividend behind the 77 and repeat the process: 777 / 79

Let's proceed to step 7:
When dividing 777 by 79, we get 9 with a remainder of 66.
Use 9 as the next digit of our solution. 
Result so far: 32899.0
If we subtract 711 from 777, we get 66.
Include the next digit (7) from the dividend after 66, then repeat: 667 / 79

On to step 8:
If we divide 667 by 79, we get 8 and a remainder of 35.
Use 8 as the next digit of our solution. 
Result so far: 328998.0
The remainder is 35 after subtracting 632 from 667.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 9:
79 goes into 350 4 times with a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 328998.4
Subtract 316 from 350 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 10:
If we divide 340 by 79, we get 4 and a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 328998.44
If we subtract 316 from 340, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 328998.44 with a remainder of 0.024.
