25815077 ÷ 348 
We want to divide 25815077 by 348.

Advancing to step 1:
If we divide 2 by 348, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 348

Advancing to step 2:
25 divided by 348 is 0 with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Fetch the next digit (8) from the dividend, attach it to 25 and continue: 258 / 348

Step 3:
258 divided by 348 is 0 with a remainder of 258.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 258, we get 258.
Take the next digit (1) from the dividend and append it to 258, then repeat: 2581 / 348

Going ahead to step 4:
348 can be fit into 2581 7 times, resulting in a remainder of 145.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 145 after subtracting 2436 from 2581.
Bring next digit (5) of the dividend behind the 145 and repeat the process: 1455 / 348

Let's proceed to step 5:
348 goes into 1455 4 times with a remainder of 63.
The next digit of our result is 4. 
Result so far: 74.0
Subtract 1392 from 1455 to get 63.
Include the next digit (0) from the dividend after 63, then repeat: 630 / 348

Step 6:
When dividing 630 by 348, we get 1 with a remainder of 282.
The next digit of our result is 1. 
Result so far: 741.0
The remainder is 282 after subtracting 348 from 630.
Grab the next digit (7) from the dividend, add it to 282, then carry on: 2827 / 348

Going ahead to step 7:
When dividing 2827 by 348, we get 8 with a remainder of 43.
Record the quotient 8 as the next digit in the result. 
Result so far: 7418.0
Subtracting 2784 from 2827 leaves us with 43.
Include the next digit (7) from the dividend after 43, then repeat: 437 / 348

Going ahead to step 8:
348 can be fit into 437 1 times, resulting in a remainder of 89.
Put 1 as the next digit of the answer. 
Result so far: 74181.0
Subtracting 348 from 437 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 9:
If we divide 890 by 348, we get 2 and a remainder of 194.
The next digit of our result is 2. 
Result so far: 74181.2
The remainder is 194 after subtracting 696 from 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

On to step 10:
The number 348 fits into 1940 5 times, leaving a remainder of 200.
Write down 5 as next digit of the result. 
Result so far: 74181.25
If we take 1740 away from 1940, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 11:
If we divide 2000 by 348, we get 5 and a remainder of 260.
Use 5 as the next digit of our solution. 
Result so far: 74181.255
If we take 1740 away from 2000, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

The final result is 74181.255 with a remainder of 0.026.
