We look at the division of 85243250 by 257 
Let's see how many times 257 fits into 85243250.

Going ahead to step 1:
257 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 257

Going ahead to step 2:
257 can be fit into 85 0 times, resulting in a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Bring next digit (2) of the dividend behind the 85 and repeat the process: 852 / 257

Let's proceed to step 3:
257 goes into 852 3 times with a remainder of 81.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 81 after subtracting 771 from 852.
Bring next digit (4) of the dividend behind the 81 and repeat the process: 814 / 257

Moving on to step 4:
814 divided by 257 is 3 with a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Subtract 771 from 814 to get 43.
Fetch the next digit (3) from the dividend, attach it to 43 and continue: 433 / 257

Moving on to step 5:
433 divided by 257 is 1 with a remainder of 176.
Use 1 as the next digit of our solution. 
Result so far: 331.0
If we subtract 257 from 433, we get 176.
Grab the next digit (2) from the dividend, add it to 176, then carry on: 1762 / 257

On to step 6:
The number 257 fits into 1762 6 times, leaving a remainder of 220.
Put 6 as the next digit of the answer. 
Result so far: 3316.0
Deduct 1542 from 1762 and we're left with 220.
Append the next digit (5) from the dividend to 220 and continue with: 2205 / 257

Moving on to step 7:
2205 divided by 257 is 8 with a remainder of 149.
Use 8 as the next digit of our solution. 
Result so far: 33168.0
If we subtract 2056 from 2205, we get 149.
Fetch the next digit (0) from the dividend, attach it to 149 and continue: 1490 / 257

Let's proceed to step 8:
1490 divided by 257 is 5 with a remainder of 205.
Use 5 as the next digit of our solution. 
Result so far: 331685.0
If we take 1285 away from 1490, we end up with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Let's proceed to step 9:
2050 divided by 257 is 7 with a remainder of 251.
Write down 7 as next digit of the result. 
Result so far: 331685.7
If we subtract 1799 from 2050, we get 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

On to step 10:
If we divide 2510 by 257, we get 9 and a remainder of 197.
The number 9 becomes the next digit in our result. 
Result so far: 331685.79
Subtract 2313 from 2510 to get 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Step 11:
The number 257 fits into 1970 7 times, leaving a remainder of 171.
Put 7 as the next digit of the answer. 
Result so far: 331685.797
The remainder is 171 after subtracting 1799 from 1970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Moving on to step 12:
1710 divided by 257 is 6 with a remainder of 168.
Put 6 as the next digit of the answer. 
Result so far: 331685.7976
The remainder is 168 after subtracting 1542 from 1710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 13:
1680 divided by 257 is 6 with a remainder of 138.
The next digit of our result is 6. 
Result so far: 331685.79766
If we take 1542 away from 1680, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

The final result is 331685.79766 with a remainder of 0.000138.
