206421 ÷ 14 
Our goal is to divide 206421 by 14.

Advancing to step 1:
When dividing 2 by 14, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 14

Advancing to step 2:
The number 14 fits into 20 1 times, leaving a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 14 from 20 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 14

Going ahead to step 3:
The number 14 fits into 66 4 times, leaving a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Deduct 56 from 66 and we're left with 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 14

Let's proceed to step 4:
104 divided by 14 is 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 147.0
Subtract 98 from 104 to get 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 14

Advancing to step 5:
14 can be fit into 62 4 times, resulting in a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 1474.0
Subtracting 56 from 62 leaves us with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 14

Advancing to step 6:
14 can be fit into 61 4 times, resulting in a remainder of 5.
The next digit of our result is 4. 
Result so far: 14744.0
Subtracting 56 from 61 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
When dividing 50 by 14, we get 3 with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 14744.3
Deduct 42 from 50 and we're left 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.

Step 8:
14 goes into 80 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 14744.35
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:
If we divide 100 by 14, we get 7 and a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 14744.357
Subtract 98 from 100 to 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.

Advancing to step 10:
When dividing 20 by 14, we get 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 14744.3571
Subtract 14 from 20 to 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.

Moving on to step 11:
14 goes into 60 4 times with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 14744.35714
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.

Step 12:
When dividing 40 by 14, we get 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 14744.357142
Deduct 28 from 40 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.

On to step 13:
When dividing 120 by 14, we get 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 14744.3571428
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:
When dividing 80 by 14, we get 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 14744.35714285
The remainder is 10 after subtracting 70 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 14744.35714285, with a leftover of 1e-08.
