We look at the division of 428406 by 14 
We're looking to find how many times 14 goes into 428406.

Going ahead to step 1:
4 divided by 14 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 14

Moving on to step 2:
14 goes into 42 3 times with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 42 away from 42, we end up with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 14

On to step 3:
8 divided by 14 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 30.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 14

Moving on to step 4:
The number 14 fits into 84 6 times, leaving a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 306.0
Subtracting 84 from 84 leaves us with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 14

Step 5:
0 divided by 14 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3060.0
Subtracting 0 from 0 leaves us with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 14

Advancing to step 6:
14 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 30600.0
Subtracting 0 from 6 leaves us 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.

Going ahead to step 7:
14 goes into 60 4 times with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 30600.4
If we subtract 56 from 60, we get 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 8:
When dividing 40 by 14, we get 2 with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 30600.42
Subtracting 28 from 40 leaves us 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 9:
120 divided by 14 is 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 30600.428
If we take 112 away from 120, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
14 goes into 80 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 30600.4285
Subtract 70 from 80 to 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.

On to step 11:
If we divide 100 by 14, we get 7 and a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 30600.42857
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.

Going ahead to step 12:
When dividing 20 by 14, we get 1 with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 30600.428571
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.

Going ahead to step 13:
60 divided by 14 is 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 30600.4285714
Subtracting 56 from 60 leaves us 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.

On to step 14:
14 can be fit into 40 2 times, resulting in a remainder of 12.
The next digit of our result is 2. 
Result so far: 30600.42857142
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.

The final outcome is 30600.42857142, with a leftover of 1.2e-08.
