Let's divide 31491927 by 257
Our goal is to divide 31491927 by 257.

On to step 1:
3 divided by 257 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 257

Going ahead to step 2:
If we divide 31 by 257, we get 0 and a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Include the next digit (4) from the dividend after 31, then repeat: 314 / 257

Going ahead to step 3:
257 goes into 314 1 times with a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 57 after subtracting 257 from 314.
Include the next digit (9) from the dividend after 57, then repeat: 579 / 257

Going ahead to step 4:
257 goes into 579 2 times with a remainder of 65.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 514 from 579 to get 65.
Fetch the next digit (1) from the dividend, attach it to 65 and continue: 651 / 257

Moving on to step 5:
257 can be fit into 651 2 times, resulting in a remainder of 137.
Put 2 as the next digit of the answer. 
Result so far: 122.0
If we subtract 514 from 651, we get 137.
Append the next digit (9) from the dividend to 137 and continue with: 1379 / 257

On to step 6:
1379 divided by 257 is 5 with a remainder of 94.
The number 5 becomes the next digit in our result. 
Result so far: 1225.0
Deduct 1285 from 1379 and we're left with 94.
Include the next digit (2) from the dividend after 94, then repeat: 942 / 257

Moving on to step 7:
If we divide 942 by 257, we get 3 and a remainder of 171.
Write down 3 as next digit of the result. 
Result so far: 12253.0
Subtracting 771 from 942 leaves us with 171.
Take the next digit (7) from the dividend and append it to 171, then repeat: 1717 / 257

Let's proceed to step 8:
The number 257 fits into 1717 6 times, leaving a remainder of 175.
The number 6 becomes the next digit in our result. 
Result so far: 122536.0
The remainder is 175 after subtracting 1542 from 1717.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Let's proceed to step 9:
257 can be fit into 1750 6 times, resulting in a remainder of 208.
Write down 6 as next digit of the result. 
Result so far: 122536.6
If we subtract 1542 from 1750, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 10:
The number 257 fits into 2080 8 times, leaving a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 122536.68
Subtracting 2056 from 2080 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 11:
257 can be fit into 240 0 times, resulting in a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 122536.68
Subtracting 0 from 240 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 12:
The number 257 fits into 2400 9 times, leaving a remainder of 87.
The number 9 becomes the next digit in our result. 
Result so far: 122536.6809
If we take 2313 away from 2400, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 13:
When dividing 870 by 257, we get 3 with a remainder of 99.
Use 3 as the next digit of our solution. 
Result so far: 122536.68093
Deduct 771 from 870 and we're left with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Step 14:
The number 257 fits into 990 3 times, leaving a remainder of 219.
Record the quotient 3 as the next digit in the result. 
Result so far: 122536.680933
Subtracting 771 from 990 leaves us with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

After the division, we end up with 122536.680933 and a remainder of 2.19e-05.
