16681312 ÷ 257 
We're looking to find how many times 257 goes into 16681312.

Moving on to step 1:
The number 257 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 257

Let's proceed to step 2:
16 divided by 257 is 0 with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 257

On to step 3:
257 goes into 166 0 times with a remainder of 166.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 166, we end up with 166.
Bring next digit (8) of the dividend behind the 166 and repeat the process: 1668 / 257

Going ahead to step 4:
The number 257 fits into 1668 6 times, leaving a remainder of 126.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 1542 from 1668, we get 126.
Fetch the next digit (1) from the dividend, attach it to 126 and continue: 1261 / 257

On to step 5:
If we divide 1261 by 257, we get 4 and a remainder of 233.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
Subtract 1028 from 1261 to get 233.
Take the next digit (3) from the dividend and append it to 233, then repeat: 2333 / 257

Advancing to step 6:
If we divide 2333 by 257, we get 9 and a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 649.0
The remainder is 20 after subtracting 2313 from 2333.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 257

Step 7:
If we divide 201 by 257, we get 0 and a remainder of 201.
Put 0 as the next digit of the answer. 
Result so far: 6490.0
The remainder is 201 after subtracting 0 from 201.
Grab the next digit (2) from the dividend, add it to 201, then carry on: 2012 / 257

On to step 8:
2012 divided by 257 is 7 with a remainder of 213.
The next digit of our result is 7. 
Result so far: 64907.0
Subtracting 1799 from 2012 leaves us with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Step 9:
If we divide 2130 by 257, we get 8 and a remainder of 74.
Record the quotient 8 as the next digit in the result. 
Result so far: 64907.8
The remainder is 74 after subtracting 2056 from 2130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 10:
When dividing 740 by 257, we get 2 with a remainder of 226.
Write down 2 as next digit of the result. 
Result so far: 64907.82
Subtracting 514 from 740 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Moving on to step 11:
If we divide 2260 by 257, we get 8 and a remainder of 204.
The number 8 becomes the next digit in our result. 
Result so far: 64907.828
Subtracting 2056 from 2260 leaves us with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 12:
If we divide 2040 by 257, we get 7 and a remainder of 241.
Put 7 as the next digit of the answer. 
Result so far: 64907.8287
Subtracting 1799 from 2040 leaves us with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Moving on to step 13:
2410 divided by 257 is 9 with a remainder of 97.
Use 9 as the next digit of our solution. 
Result so far: 64907.82879
Deduct 2313 from 2410 and we're left with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Let's proceed to step 14:
257 can be fit into 970 3 times, resulting in a remainder of 199.
Use 3 as the next digit of our solution. 
Result so far: 64907.828793
The remainder is 199 after subtracting 771 from 970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Advancing to step 15:
257 can be fit into 1990 7 times, resulting in a remainder of 191.
The number 7 becomes the next digit in our result. 
Result so far: 64907.8287937
Subtracting 1799 from 1990 leaves us with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

On to step 16:
When dividing 1910 by 257, we get 7 with a remainder of 111.
The next digit of our result is 7. 
Result so far: 64907.82879377
Subtracting 1799 from 1910 leaves us with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

The quotient of the division is 64907.82879377, and the remainder is 1.11e-07.
