Let's divide 25999528 by 398
We want to divide 25999528 by 398.

On to step 1:
When dividing 2 by 398, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 398

On to step 2:
When dividing 25 by 398, we get 0 with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Take the next digit (9) from the dividend and append it to 25, then repeat: 259 / 398

Moving on to step 3:
The number 398 fits into 259 0 times, leaving a remainder of 259.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 259, we get 259.
Bring next digit (9) of the dividend behind the 259 and repeat the process: 2599 / 398

Advancing to step 4:
The number 398 fits into 2599 6 times, leaving a remainder of 211.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 211 after subtracting 2388 from 2599.
Grab the next digit (9) from the dividend, add it to 211, then carry on: 2119 / 398

Going ahead to step 5:
398 can be fit into 2119 5 times, resulting in a remainder of 129.
Use 5 as the next digit of our solution. 
Result so far: 65.0
If we take 1990 away from 2119, we end up with 129.
Take the next digit (5) from the dividend and append it to 129, then repeat: 1295 / 398

Going ahead to step 6:
The number 398 fits into 1295 3 times, leaving a remainder of 101.
The number 3 becomes the next digit in our result. 
Result so far: 653.0
The remainder is 101 after subtracting 1194 from 1295.
Take the next digit (2) from the dividend and append it to 101, then repeat: 1012 / 398

Step 7:
The number 398 fits into 1012 2 times, leaving a remainder of 216.
Record the quotient 2 as the next digit in the result. 
Result so far: 6532.0
If we subtract 796 from 1012, we get 216.
Take the next digit (8) from the dividend and append it to 216, then repeat: 2168 / 398

Advancing to step 8:
2168 divided by 398 is 5 with a remainder of 178.
The number 5 becomes the next digit in our result. 
Result so far: 65325.0
If we subtract 1990 from 2168, we get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Going ahead to step 9:
398 can be fit into 1780 4 times, resulting in a remainder of 188.
The next digit of our result is 4. 
Result so far: 65325.4
Deduct 1592 from 1780 and we're left with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Going ahead to step 10:
When dividing 1880 by 398, we get 4 with a remainder of 288.
Put 4 as the next digit of the answer. 
Result so far: 65325.44
Subtract 1592 from 1880 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

The final outcome is 65325.44, with a leftover of 0.288.
