We look at the division of 257490 by 14 
We want to figure out the number of times 257490 can be divided by 14.

Let's proceed to step 1:
If we divide 2 by 14, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 14

Let's proceed to step 2:
14 goes into 25 1 times with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 14 from 25 and we're left with 11.
Bring next digit (7) of the dividend behind the 11 and repeat the process: 117 / 14

On to step 3:
If we divide 117 by 14, we get 8 and a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtracting 112 from 117 leaves us with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 14

Step 4:
14 can be fit into 54 3 times, resulting in a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 183.0
Deduct 42 from 54 and we're left with 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 14

Going ahead to step 5:
14 can be fit into 129 9 times, resulting in a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 1839.0
Subtract 126 from 129 to get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 14

Step 6:
14 can be fit into 30 2 times, resulting in a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 18392.0
If we subtract 28 from 30, we get 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 7:
14 goes into 20 1 times with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 18392.1
The remainder is 6 after subtracting 14 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
60 divided by 14 is 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 18392.14
The remainder is 4 after subtracting 56 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
The number 14 fits into 40 2 times, leaving a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 18392.142
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.

Moving on to step 10:
If we divide 120 by 14, we get 8 and a remainder of 8.
The next digit of our result is 8. 
Result so far: 18392.1428
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.

On to step 11:
When dividing 80 by 14, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 18392.14285
If we subtract 70 from 80, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 12:
When dividing 100 by 14, we get 7 with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 18392.142857
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 13:
20 divided by 14 is 1 with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 18392.1428571
If we subtract 14 from 20, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 14:
60 divided by 14 is 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 18392.14285714
The remainder is 4 after subtracting 56 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 18392.14285714, with a leftover of 4e-09.
