12851815 divided by 254 
Let's see how many times 254 fits into 12851815.

Moving on to step 1:
254 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 254

Moving on to step 2:
When dividing 12 by 254, we get 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 254

Going ahead to step 3:
The number 254 fits into 128 0 times, leaving a remainder of 128.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 128 leaves us with 128.
Append the next digit (5) from the dividend to 128 and continue with: 1285 / 254

Step 4:
When dividing 1285 by 254, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 15 after subtracting 1270 from 1285.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 254

Advancing to step 5:
151 divided by 254 is 0 with a remainder of 151.
The next digit of our result is 0. 
Result so far: 50.0
The remainder is 151 after subtracting 0 from 151.
Fetch the next digit (8) from the dividend, attach it to 151 and continue: 1518 / 254

On to step 6:
When dividing 1518 by 254, we get 5 with a remainder of 248.
Write down 5 as next digit of the result. 
Result so far: 505.0
Deduct 1270 from 1518 and we're left with 248.
Include the next digit (1) from the dividend after 248, then repeat: 2481 / 254

Moving on to step 7:
254 can be fit into 2481 9 times, resulting in a remainder of 195.
Use 9 as the next digit of our solution. 
Result so far: 5059.0
If we subtract 2286 from 2481, we get 195.
Take the next digit (5) from the dividend and append it to 195, then repeat: 1955 / 254

On to step 8:
The number 254 fits into 1955 7 times, leaving a remainder of 177.
Put 7 as the next digit of the answer. 
Result so far: 50597.0
Subtract 1778 from 1955 to get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Moving on to step 9:
254 goes into 1770 6 times with a remainder of 246.
Use 6 as the next digit of our solution. 
Result so far: 50597.6
Deduct 1524 from 1770 and we're left with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Moving on to step 10:
2460 divided by 254 is 9 with a remainder of 174.
Record the quotient 9 as the next digit in the result. 
Result so far: 50597.69
If we subtract 2286 from 2460, we get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Step 11:
254 can be fit into 1740 6 times, resulting in a remainder of 216.
Record the quotient 6 as the next digit in the result. 
Result so far: 50597.696
Subtract 1524 from 1740 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 12:
254 can be fit into 2160 8 times, resulting in a remainder of 128.
Put 8 as the next digit of the answer. 
Result so far: 50597.6968
The remainder is 128 after subtracting 2032 from 2160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 13:
When dividing 1280 by 254, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 50597.69685
Deduct 1270 from 1280 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
The number 254 fits into 100 0 times, leaving a remainder of 100.
The next digit of our result is 0. 
Result so far: 50597.69685
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 15:
254 can be fit into 1000 3 times, resulting in a remainder of 238.
The next digit of our result is 3. 
Result so far: 50597.6968503
Deduct 762 from 1000 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 16:
2380 divided by 254 is 9 with a remainder of 94.
Write down 9 as next digit of the result. 
Result so far: 50597.69685039
Deduct 2286 from 2380 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

The final result is 50597.69685039 with a remainder of 9.4e-08.
