8145231 divided by 257 
We want to figure out the number of times 8145231 can be divided by 257.

Let's proceed to step 1:
When dividing 8 by 257, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 257

Advancing to step 2:
If we divide 81 by 257, we get 0 and a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Include the next digit (4) from the dividend after 81, then repeat: 814 / 257

Step 3:
The number 257 fits into 814 3 times, leaving a remainder of 43.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 771 away from 814, we end up with 43.
Take the next digit (5) from the dividend and append it to 43, then repeat: 435 / 257

Let's proceed to step 4:
257 can be fit into 435 1 times, resulting in a remainder of 178.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
If we take 257 away from 435, we end up with 178.
Take the next digit (2) from the dividend and append it to 178, then repeat: 1782 / 257

On to step 5:
When dividing 1782 by 257, we get 6 with a remainder of 240.
Record the quotient 6 as the next digit in the result. 
Result so far: 316.0
Deduct 1542 from 1782 and we're left with 240.
Include the next digit (3) from the dividend after 240, then repeat: 2403 / 257

Advancing to step 6:
257 can be fit into 2403 9 times, resulting in a remainder of 90.
Put 9 as the next digit of the answer. 
Result so far: 3169.0
Deduct 2313 from 2403 and we're left with 90.
Bring next digit (1) of the dividend behind the 90 and repeat the process: 901 / 257

Going ahead to step 7:
When dividing 901 by 257, we get 3 with a remainder of 130.
Use 3 as the next digit of our solution. 
Result so far: 31693.0
Subtracting 771 from 901 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 8:
The number 257 fits into 1300 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 31693.5
If we subtract 1285 from 1300, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
When dividing 150 by 257, we get 0 with a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 31693.5
If we take 0 away from 150, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 10:
When dividing 1500 by 257, we get 5 with a remainder of 215.
Put 5 as the next digit of the answer. 
Result so far: 31693.505
Deduct 1285 from 1500 and we're left with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

On to step 11:
When dividing 2150 by 257, we get 8 with a remainder of 94.
Write down 8 as next digit of the result. 
Result so far: 31693.5058
If we subtract 2056 from 2150, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Going ahead to step 12:
If we divide 940 by 257, we get 3 and a remainder of 169.
Use 3 as the next digit of our solution. 
Result so far: 31693.50583
If we subtract 771 from 940, we get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Moving on to step 13:
257 goes into 1690 6 times with a remainder of 148.
Write down 6 as next digit of the result. 
Result so far: 31693.505836
Subtract 1542 from 1690 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 14:
When dividing 1480 by 257, we get 5 with a remainder of 195.
Write down 5 as next digit of the result. 
Result so far: 31693.5058365
The remainder is 195 after subtracting 1285 from 1480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Moving on to step 15:
257 goes into 1950 7 times with a remainder of 151.
The next digit of our result is 7. 
Result so far: 31693.50583657
The remainder is 151 after subtracting 1799 from 1950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

The quotient of the division is 31693.50583657, and the remainder is 1.51e-07.
