We're dividing 257486 by 14 
We want to figure out the number of times 257486 can be divided by 14.

Moving on to step 1:
14 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 14

Moving on to step 2:
25 divided by 14 is 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 14 from 25, we get 11.
Bring next digit (7) of the dividend behind the 11 and repeat the process: 117 / 14

Moving on to step 3:
If we divide 117 by 14, we get 8 and a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we take 112 away from 117, we end up with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 14

Advancing to step 4:
If we divide 54 by 14, we get 3 and a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 183.0
If we subtract 42 from 54, we get 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 14

Step 5:
14 can be fit into 128 9 times, resulting in a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 1839.0
Subtract 126 from 128 to get 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 14

On to step 6:
If we divide 26 by 14, we get 1 and a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 18391.0
Deduct 14 from 26 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
When dividing 120 by 14, we get 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 18391.8
If we subtract 112 from 120, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
The number 14 fits into 80 5 times, leaving a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 18391.85
Subtracting 70 from 80 leaves us 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.

Moving on to step 9:
100 divided by 14 is 7 with a remainder of 2.
The next digit of our result is 7. 
Result so far: 18391.857
Subtracting 98 from 100 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
20 divided by 14 is 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 18391.8571
Deduct 14 from 20 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 11:
If we divide 60 by 14, we get 4 and a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 18391.85714
Deduct 56 from 60 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 12:
14 goes into 40 2 times with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 18391.857142
The remainder is 12 after subtracting 28 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 13:
120 divided by 14 is 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 18391.8571428
Subtract 112 from 120 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 14:
14 can be fit into 80 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 18391.85714285
Subtracting 70 from 80 leaves us 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.

The quotient of the division is 18391.85714285, and the remainder is 1e-08.
