We're dividing 25645796 by 818 
Our goal is to divide 25645796 by 818.

Step 1:
2 divided by 818 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 818

Going ahead to step 2:
If we divide 25 by 818, we get 0 and a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Bring next digit (6) of the dividend behind the 25 and repeat the process: 256 / 818

Step 3:
If we divide 256 by 818, we get 0 and a remainder of 256.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 256, we get 256.
Bring next digit (4) of the dividend behind the 256 and repeat the process: 2564 / 818

Going ahead to step 4:
The number 818 fits into 2564 3 times, leaving a remainder of 110.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 2454 from 2564, we get 110.
Bring next digit (5) of the dividend behind the 110 and repeat the process: 1105 / 818

Step 5:
818 goes into 1105 1 times with a remainder of 287.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Deduct 818 from 1105 and we're left with 287.
Fetch the next digit (7) from the dividend, attach it to 287 and continue: 2877 / 818

Moving on to step 6:
When dividing 2877 by 818, we get 3 with a remainder of 423.
Put 3 as the next digit of the answer. 
Result so far: 313.0
Deduct 2454 from 2877 and we're left with 423.
Fetch the next digit (9) from the dividend, attach it to 423 and continue: 4239 / 818

Let's proceed to step 7:
If we divide 4239 by 818, we get 5 and a remainder of 149.
Record the quotient 5 as the next digit in the result. 
Result so far: 3135.0
Subtracting 4090 from 4239 leaves us with 149.
Append the next digit (6) from the dividend to 149 and continue with: 1496 / 818

Going ahead to step 8:
When dividing 1496 by 818, we get 1 with a remainder of 678.
The next digit of our result is 1. 
Result so far: 31351.0
The remainder is 678 after subtracting 818 from 1496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6780, and continue the process.

Step 9:
The number 818 fits into 6780 8 times, leaving a remainder of 236.
Record the quotient 8 as the next digit in the result. 
Result so far: 31351.8
The remainder is 236 after subtracting 6544 from 6780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Step 10:
2360 divided by 818 is 2 with a remainder of 724.
Put 2 as the next digit of the answer. 
Result so far: 31351.82
Subtract 1636 from 2360 to get 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Step 11:
The number 818 fits into 7240 8 times, leaving a remainder of 696.
Put 8 as the next digit of the answer. 
Result so far: 31351.828
If we subtract 6544 from 7240, we get 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Let's proceed to step 12:
When dividing 6960 by 818, we get 8 with a remainder of 416.
Write down 8 as next digit of the result. 
Result so far: 31351.8288
The remainder is 416 after subtracting 6544 from 6960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Our division results in 31351.8288 with a remaining 0.00416.
